You are on an analysis team for a SOA (service oriented architecture) project that may impact how the systems development group develops systems. This is a challenge for some of the development team who are used to more traditional approaches. You are focusing less on the as-is system and more on the to-be system. You really want to understand the fears and reluctance within the development team. Develop an interview plan: who would you interview? Why? What kinds of questions would you use? How might you get to the real depths of concerns?

Answer You would want to understand what the reluctance is – and try to overcome it. Reassure them that their jobs are not in jeopardy (if that is true); make sure that they know that you are not a spy trying to get them fired. Make sure they know the business value of the system and why you are doing this analysis.

They seem to be taking glances at him to see if he is writing down comments about their processes. He has insisted he just wants to know how their work is accomplished and ultimately the project team will deliver a system that is better and easier to use for them. He has heard from a ‘friend-of-a-friend-of-a-friend’ of one of the claim workers that they suspect that he is also connected to the HR department and that their jobs are on the line. How might he accomplish his observation activity?

Answer Reassure them that he is NOT connected to HR; reassure them about the value of the system; and he also needs to be a little less obtrusive. It might be possible to have a webcam installed to do the observation remotely.

78. Your project sponsor has suggested several key people to get involved in a JAD session.

You cannot include all of the people, so you pick and choose those to invite to the session.

You hear from the informal grapevine that one person that was not invited is upset and feels left out. This person has been with the company for 12 years and had a lot of expertise.

What should you do? Why? Answer Try going to the person and defusing the situation. If need be, add him/her to the JAD session.

Do an interview with him. Also check with his/her manager to see if this is a normal behavior (for example, he/she tends to be a ‘hot-head’).

79. MetaContinental has been mandated to comply with Sarbanes-Oxley criteria. The reporting system will need to be almost completely overhauled to comply. The project team realizes that this will be a business process reengineering project. How should they go about gathering business requirements for the new system? Should they have interviews? Who? Why? How many? Should they have a JAD session? What other techniques should they use for gathering requirements?

Answer This will focus more on BPR – so less looking at the as-is system. The requirements might be significantly from outside – such as attending training sessions on SOX, gathering information, hiring a consultant, etc. The staff will need to be involved as well – such as the accounting manager, CFO, others to understand what they know about SOX and how to gear up for this.

Shaunti has trouble identifying (a) the actor and (b) the trigger for a use case. What directions would you suggest to her?

Answer The primary actor is generally an external user that triggers the event to which the system responds.

Frequently this is a person external to the system (like a customer or a patient), but could also be an organization or another information system. Triggers are the event that causes the use case to begin – like a customer placing an order, a shipping arriving at the loading dock (external triggers) or a temporal trigger (generally something like a specific date / time – like the end-of-the-month report is due).

Essays 79. You have a student registration system (simplified) with three entities: Student, Professor, and Class.

Assume standard attributes for the three entities. What might be the relationships, cardinality and modality between the three?

Answer Answers will vary; but something like: Professor teach classes (probably 1:M); a class is taught by 1 professor; students take classes (1:M); it might be possible to have a class with no students (so modality might be null) – such as an advanced nuclear physics class taught at 5:00 a.m. ; it might be possible that a professor isn’t teaching this semester (on sabbatical or doing research projects) – so modality of null; could a student not be taking any classes?

If so that could also have a modality of null (might be doing an internship that is not registered with the campus; might be on a study-abroad trip that isn’t for credit and is not registered for; might have dropped out for the semester, etc.); professors have many students and student have many professors (M:N); and again if a professor is on sabbatical or doing research may not have students and if a student is not enrolled, he/she may not have any professors.

Response: Creating an Entity Relationship Diagram Difficulty: hard – mainly due to the number of assumptions which must be made to make a “correct” diagram

80. In the sample data for the STUDENT entity, there are repeating values for class and semester attributes. For example, Adam Murphy took CIS 370 section 2 in fall 2008; Brenda Olson took CIS 370 section 2 in fall 2008; Jing Zhang took CIS 370 section 2 in fall 2008; etc. What is the process to modify this entity so that there are no attributes with multiple values?

Answer This is to put the entity into First Normal Form (1NF). Generally, you will create a new entity CoursesTaken where each course each semester each section is placed and a relationship will be drawn between the entities. For this example, one entry in the Courses-Taken entity will be: CIS 370-Section2-fall2008 – and a relationship between the courses-Taken and the students will be drawn.

Response: Appendix 5A: Normalizing the Data Model Difficulty: hard

Chapter 5 – Systems Analysis and Design – Dennis / Wixom / Roth - page 18 81. How do you validate an ERD? Answer Creating and validating ERDs can be tough. It takes experience to draw ERDs well and there are not all that many guidelines and rules. You will want to verify that entities are complete (i.e. have all the needed attributes, have consistent names (not client at some point and customer at another point), that relationships are identified and drawn; that cardinality (1:1; 1:N or M:N) is drawn – and if possible M:N cardinalities are avoided by creating entities in between the M:N entities; that modality is identified (null or non-null); and that eventually the ERD is normalized to 3NF. It takes time and patience to learn and do this!!!

Response: Validating an Entity Relationship Diagram and Appendix 6A: Normalizing the Data Model Difficulty: hard 82. Discuss what should be done to ensure that the entity relationship diagrams balance with the data flow diagrams. What is the consequence of failing to balance these models?

Answer The key to balancing these diagrams is to remember that both models must refer to exactly the same 'data foundation' of the system. Every entity on the data model should correspond to a data store on a DFD. Also, all the data elements that comprise the data flows in the DFDs should appear as attributes of entities in the data model. Similarly, the attributes of the data model entities should be found in the process models; otherwise, the data is probably not used by the business system and should not be stored. If the analysts do not balance the data and process models, then the system will either omit critical data or will contain unnecessary data.

Essay: 65. At the end of the design phase, there is a document named the system specification that describes the different design documents and their uses. What is the consolidated purpose of this deliverable and why is it important?

Answer At the end of the design phase, the project team creates the final deliverable for the phase called the system specification. This document contains all of the design documents just described: physical process models, physical data model, architecture design, hardware and software specification, interface design, data storage design, and program design. Collectively, the system specification conveys exactly what system the project team will implement during the implementation phase of the SDLC.

66.

What types of influences are there on determining the type of installation to pursue with relation to resources and the acquisition of a new system?

Answer When considering a new system, there are five different items to consider.

First, one must consider the business need. Is it unique? Is it able to be solved with simple packaged software? Is the need core to our system? This will influence the project strategy as a whole and determine the overall expense of the project.

Second, in-house experience will determine whether or not there is enough skill located within the current set of employees to manufacture the desired outcome.

Third, project skills: do we have the ability to learn this with our programmers or will we need to outsource programmers to assist us?

Fourth, project management, can we complete the task with our current management team or will we need consultants to assist us in completing the task?

Fifth, how much time do we have? Will we be able to complete the project quickly or are we on a tight time budget? Will we need additional manpower to push the project through?

67. What are the three acquisition strategies? Describe them.

Answer Custom development, packaged software, and outsourcing are the three acquisition strategies.

Custom development utilizes the project team’s skills in creating a ground-up software solution.

This is often the most time consuming and demanding on in-house resources. This is a great alternative if the nature of the project is conducive to the skills already present in-house and the need is core to the business itself.

Packaged software is by far the fastest of the implementation strategies. This option is when the acquisition team installs a pre-written packaged software solution into its current IT configuration. Often times, workarounds are required to intertwine the systems; however, this takes the bulk of the programming out of the equation and doesn’t completely remove the programmers from their everyday tasks for as long as a custom development strategy.

Outsourcing utilizes external programmers and engineers. This is often expensive if the terms of the contract are not laid out clearly and accurately in the beginning. In an ideal situation, external programmers can be brought in-house so they may educate the current team for future projects. If this is not an alternative and time is of the essence, exporting the responsibilities to an external vendor can expedite the process of programming. A significant downside to outsourcing is that your system is exposed to the outside vendor’s staff, which can be a security concern if the system data and/or processes are mission-critical or of a sensitive nature.

68. Jeff is an analyst. The human resources department is very unhappy with their payroll package. They want the information systems department to write them a new package as they think they have unique needs that can’t be meet with a packaged solution. What should Jeff do?

Answer Payroll is a very common application and there are many good payroll programs on the market.

Jeff really needs to understand what the problems with the current package are. Is it old (i.e. only runs on a mainframe system)? What functions does HR want to do that the package does not support? In that payroll information must be reported to state and federal officials for tax reasons, it probably does’t make sense to write a complete package but to find one that meets HR needs. After a detailed investigation, it may be best to create either an RPI or RPQ to get additional information and bids from potential vendors.

Short Answer/Essay 54. There are three basic application architectures discussed in the chapter, each one having its distinctive attributes. Identify the four types of architectures that emerge from these three application architectures and provide a short explanation of each, along with key advantages and disadvantages. The four general architectures commonly utilized are server-based, clientbased, client-server, and client-server tier architectures.

Answer The server-based architecture is the original and most basic of the four. It allows a server to handle all four functions of software systems which are data storage, data access logic, application logic and presentation logic. The shortcoming of this architecture design is its lack of scalability and high network demands on the central mainframe.

The client-based architecture is another simple architecture that is quite stable. This system handles the distribution of data access, application, and presentation logic by distributing the responsibilities amongst the client and server computers. The client computer (terminal) handles the presentation logic, application logic and the data access logic. The server is simply a storage unit where data is dumped and accessed. The shortcoming with this system is as the network demands grow, network circuits can become quite overburdened and slowed dramatically as the traffic increases.

The client-server architecture is a step ahead of the previous examples in that it distributes the processing responsibilities amongst the systems to minimize the resources each individual process takes up. The client computer (terminal) is responsible for managing the presentation logic and sometimes the application logic while the server handles data access logic, storage logic and occasionally (when not handled by the terminal) the application logic. While these server systems are advanced, they are also complex and difficult to maintain. Client-server architecture systems require a vast knowledge of both the terminal systems and the server systems, often times requiring outside resources to be utilized in the maintenance of the system.

Client-server tiers represent an extension of the client-server architecture by further separating the responsibility for system functions amongst multiple, specialized servers. For instance, many current generation web-based e-commerce solutions utilize a client to handle the presentation logic (web browser), a web server to handle the web-related business logic, an application server to handle order processing logic, and a database server to handle database-related tasks. The primary advantage of such n-tiered architectures is the promise of better load balancing amongst the various system components. However, the n-tiered architecture places a greater load on the network and is more difficult to program and test.

55. Describe the difference between a thick and a thin client.

Answer Thick and thin clients are found in client-server applications and they are categorized as thick or thin based on the proportion of application logic stored on the client terminal. Thick, or sometimes referred to as fat, clients are those that house a majority of the application logic.

Thin clients are those where the majority of the systems’ application logic is stored on the server.

56. Anthony is an entrepreneur of the e-commerce sort. He has asked Computers International, Inc. to develop a functional and fundamental system that will enable him to conduct business within the confines of the United States. He has asked CI, Inc. to develop a system where he wishes to: avoid opening a bricks-and-mortar storefront (incidentally that means solely internet based), be able to export files and data to Microsoft Excel spreadsheets where he can create presentations for future investors, access his files from his PDA or Blackberry from the road and have a rather stable maintenance record for minimal downtime and his avid anticipation for growth. What operational requirements are needed and why?

Answer Computers International should reply to Anthony by offering him a system that will operate off of a client-server architecture which will allow the computing needs of his whole firm to be run by both the client and the customer terminals. Additionally, his technical requirements are such that his system can present the data to a multitude of operating systems and web browsers. Anthony also has integration requirements with Microsoft Excel where he will be able to offload data in the form of a comma-separated values (CSV) document or the like to maintain compatibility with a multitude of bundled software packages. His portability requirements specify that he will need to access his data from the road via a portable web browser and his maintainability requirements specify that he wishes to minimize downtime and allow for his anticipated growth not to outpace his initial investment.

57. Joseph is an IT director at a large multinational, multibillion dollar-a-year corporation that is responsible for the distribution of highly specialized and often times custom parts. He has been charged with creating a hardware profile to dictate the performance requirements of the company’s next mainframe system. Acting as a consultant to Joe, what kinds of performance requirements are important to develop an appropriate hardware profile? What are the key issues for each of these requirements that could be recommended to the corporation’s CTO. Answer Joe should primarily be concerned with speed, capacity, availability, and reliability requirements.

He should be concerned with the speed of his network due to the international order fulfillment aspect of the firm. Also, due to the nature of the manufacturing system (custom and unique parts), there will be a tremendous number of orders generated which will further add to the bandwidth usage that will need to be handled by the system. Additionally, Joe needs to take into account the number of order transmissions made internally to the machining shop and automated machinery.

In so far as capacity, Joe should also be concerned with server space available to store the individual orders for whatever specific period of time the company sees fit. In addition, he needs to consider the total number of users needing to log in and access the ERP system at any given moment. If he does not consider the number of individuals and terminals logging into the system, he will end up with a bandwidth shortage as well as interrupted usage due to server overuse.

Finally, availability and reliability will be determined by the service hours offered by the sales team to the firm’s customers. However, there must also be a certain number of hours allowed for maintenance and upgrades each month. Due to the international time zones, most likely downtime will take place at odd hours of the morning on days that do not normally incur tremendous call volume and order processing.

58. BioFoods International is concerned with providing low cost foods to nations that cannot afford the wholesome and nutritional foods that are so common in more developed countries.

BioFoods International is adopting a new computer system that will enable our international managers to place orders with us directly, ensuring accurate and fulfilling orders to each of our constituents. What types of cultural requirements should be considered in acquiring this new system?

Answer BioFoods International should consider having a system that is multilingual, customizable, and meets legal requirements in the countries where they operate. Additionally, they should make unstated norms explicit within their system as to maintain order and to remain within the acquisition ability of the firm to avoid erroneous orders.

Essays 93. United Pharmacy is a major pharmaceutical company in Mobile Alabama. They want to go ‘on-line’ with an e-commerce pharmacy. Obviously, a lot of time and effort has gone into planning and analysis. They are working on the web user interface currently. They are considering the standard ‘shopping cart’ icon and metaphor. What others might they consider?

Answer Answers will vary. The advantage of the shopping cart icon / metaphor is that it is more-andmore a standard in the e-commerce area. They might consider a shopping ‘bag’, a ‘box’ or some other alternative, but users have come to expect a shopping ‘cart’.

Response: Define Standards Difficulty: medium

94. United Pharmacy is a major pharmaceutical company in Mobile Alabama. They want to go ‘on-line’ with an e-commerce pharmacy. For patients ordering medications online, they need to capture the medication name (like Zocor). Why should they NOT use a text box for this?

Answer Text boxes could lead to strange spellings (especially for drug names that might be hard to spell).

The best might be for the patient to indicate what the medicine is for (like cholesterol or high blood pressure) and then take them to a screen with all the various medications for that problem (so all cholesterol medicines would be listed). It might be good to have a combo box as a doctor might prescribe some new medication (that is not on the list-box menu).

Response: Entering Text Difficulty: hard

95. On the United Pharmacy online prescription system, the users want to build in some safeguards (like the user’s order too large of a quantity). If a user orders (say) 500 pills of a prescription, and the limit is 100, what kinds of processing might occur?

Answer To handle an error like this, an error message should occur (like indicating that the maximum quantity is 100, a code (for potential debugging) is listed and the user needs to check an “ok” button to acknowledge the error. After the message clears, the prompt should be back in the order quantity area.

96. Roger has coded an error message for the online prescription ordering system for United Pharmacy. His message has tried to be ‘light’ and says “Hey – you can’t do that – go back and change the quantity ordered”. Is this a good error message? Why or why not?

Answer No, that is not a good error message; humor should be either avoided or used sparingly. His message should be clearer.

97. An accountant likes to check a lot of specific accounts and records. What type of report might work best here – and why?

Ans: Detailed report – all records (or appropriate records) Response: Types of Outputs Difficulty: easy

98. The online prescription order system for United Pharmacy has over twenty different forms and screens. What might be the most important design factor – and why?

Answer Consistency is the main key here. With several forms and screen, users will want common navigation options, status lines, indications of where data is to be entered, common layout, and overall consistency in all items. (Also ease of learning.)

Response: Consistency Difficulty: medium

99. Research has shown that many detailed paper reports are not read thoroughly, not read at all, or only scanned. What should analysts do to verify the use of output reports?

Answer Analysts should work closely with users to understand their information need. If a detailed report is used daily (observation might help), then a detailed report would be good; if a report is only scanned, maybe a summary report would work best.

Essays 72. Compare and contrast cohesion and coupling.

Answer Cohesion is how well a module does processing – a module should do only one task; coupling is how closely modules are interrelated – the less the better. So, modules should be highly cohesive (only one task) and loosely coupled (little or no interaction).

Reference: Design Guidelines Difficulty: medium 73. It seems a lot of work to create structure charts, with high cohesion, loosely coupled, with high fan-in, low-fan-out, with transaction structures and transform structures. Why should an analyst bother developing structure charts and instead just pass on the specifications to the programmer?

Answer Analysts do the assigning of application development to programmers. You want programs that are easily maintained, modular, flexible, and satisfy the users. That is why structure charts and subsequent program design actions are so important.

Reference: Entire chapter Difficulty: medium 74. What is the difference between transaction structures and transform structures on a structure chart?

Answer Transaction structures generally are found in the higher levels of a DFD and are where a module performs one of a group of individual transactions and generally have few inputs and a lot of outputs; transform structures have control modules that call several subordinate modules in sequence.

75. What is a ‘top-down approach’ and why is it important when designing programs?

Answer Starting with the big picture, refining it to more detail and to a fully described scenario (the example in the text was to drive to a specific location; start with the general directions (Virginia); then the regional directions (south-central Virginia); then local directions (315 N. Elm Street, Charlottesburg, VA). Top-down approaches help the analyst create modules that will get translated into flexible, maintainable, well-designed code.

76. Structure charts show: sequence, selection and iteration. What are these factors?

Answer • Sequence shows in what order components are invoked • Selection is under what condition a module is invoked Iteration is how oft en a component is repeated Reference: Structure Chart Difficulty: medium

77. What is Fan-in and Fan-out?

Answer Fan-in describes the number of control modules that communicate with a subordinate; a module with high-fan-in has many different control modules that call it (it may be a library module) – and suggests well-written generic code; fan-out is the concept of ‘span of control’. If too many subordinate modules are associated with a single control, it might be hard to maintain and manage.

78. Summarize the quality checks that should be performed when reviewing structure charts.

Answer Design the system so that there is a high fan-in structure. Create library modules whenever possible. Limit the span of control of the control modules to no more than seven subordinates.

Make sure that each module performs only one function. The modules should sparingly share information, and make sure that the data couples that are passed are actually used by the accepting module. Control couples should be passed from low to high, not the other way around.

Also, the module should have a reasonable amount of code associated with it.

Reference: Design Guidelines Difficulty: medium 79. When putting individual components together for a structure chart you will need to identify the three basic kinds of processes in a process model. Identify these three kinds of models and describe each.

Answer Three basic kinds of processes on a process model are afferent (input), central (main processing), and efferent (output). Afferent processes are processes that provide inputs into the system.

Central processes perform critical functions in the operation of the system. Efferent processes deal with the system outputs.

ESSAYS 59. Michael is working on online documentation. He has about ten menu items; twenty items in the index; and wants to have about ten tutorial pages. How much time should he allocate to developing the documentation for these items (menus, index and tutorials)?

Answer From the “Developing Documentation” materials, we have “for good-quality documentation, this process usually takes about […] 2 hours per screen for online documentation”. This would translate into about 80 hours of work (10 + 20 + 10 (=40) * 2 for a total of 80 hours).

60. Myles is a systems analyst on a new project that involves significant programming. What is Myles doing while the programming is going on?

Answer Myles should be working on testing and documentation. The main project manager for this project should be assigning development (programming) tasks and monitoring so that the project doesn’t slip from its expected completion. As soon as some of the modules are completed, Myles can start testing (possibly with stub modules); then move into integration, system and acceptance testing. Likewise, he can be completing documentation tasks.

Reference: Developing Documentation Difficulty: medium 61. Bruce is a senior project manager. What activities should he be doing in the programming / development phase?

Answer Bruce should be overseeing and coordinating programming activities. He probably is hosting weekly project meetings, making sure that modules are progressing as planned. He is also working with other systems analysts to make sure that the testing plan has been developed and testing is going on; and that documentation is started. He also wants to make sure that scope creep is not occurring (or dealing with it), and that the project is on time. If the project does start to slip, he needs to be on top of the issue and find solutions to get it back on track – or – to extend the project time schedule if it cannot be placed back on track.

62. Jing is a project manager developing a critical project that MUST be completed by December 31st. Due to some unforeseen issues early on, the project is now two weeks behind and it is mid-November. What can/should Jing do to get the project finished by December 31st?

Answer There are lots of things that Jing can do – some of which are generally not advised. Adding additional programming staff will probably lengthen the time. If the programming is the bottleneck, it might be good to decompose complex programs into smaller modules that can be delegated to different programmers for completion. To watch the time, test plans should be ready as soon as modules are; users should be prepared to do testing as soon as possible.

Documentation can be done concurrently. If the deadline is an absolute, Jing needs to make sure that everybody, and everything is kept updated and on target. It might mean that some of the staff gets only an abbreviated Thanksgiving break – or some people (maybe testing) work during the Christmas to New Year’s break week. If any slack could occur, Jing should be exploring all avenues (can the deadline be extended to January 15th? How fixed is the end date?) to see how best to manage the project in the time left in the planned schedule.

And … if nothing else, this also needs to be a learning experience for the team so that projects stay on track in the future.

64. What is the difference between usability testing and performance testing?

Answer Usability testing is generally more important for the user-interface, while performance testing makes sure the desired response time is met. Some processes that can help might be formal usability testing (see Chapter 9) and ensuring database response time is within expected parameters as detailed in the original requirements specifications (see Chapter 11).

66. Identify three types of user documentation. Contrast when each form of documentation should be used.

Answer There are three types of user documentation: reference documents or help systems, procedure manuals, and tutorials.

Reference documents or help systems are designed to be used when the user needs to learn how to perform a specific function, such as updating a field or adding a new record. Since users may have already attempted to perform the function prior to reading the reference documentation, it must be particularly clear and brief.

Procedure manuals describe how to perform a business task such as printing a monthly report or taking a customer order. Each item in the procedure manual typically guides the user through a task that requires several functions. Procedure manual entries are normally much longer than reference document entries.

Tutorials teach people how to use major components of the system, such as the operating system or the accounts receivable system. Tutorial entries are much longer than procedure manual entries. Tutorials are typically designed to be read in sequence whereas reference documents and procedure manuals are designed to be read individually.

ESSAYS 59. What are the two ‘conversion style’ options for switching from the old system to the new system – and what are the advantages and disadvantages to each?

Answer Direct (abrupt) and parallel. Direct gets the new system installed with less cost than parallel, but also has a bigger risk; parallel lets the old and new system co-exist for a period of time – but has more costs in running two systems, but much less risk.

Reference: Selecting the Conversion Strategy Difficulty: medium 60. There are three conversion locations – what are they and give some advantages of each.

Answer Simultaneous (all at once); pilot; and phased: Simultaneous converts all locations to the new system at the same time – with the advantage of every user has the same screens, same processing, and same activities.

Pilot is when the new system is rolled out to a location (or a few locations) on a trial (pilot) basis – the main advantage is to provide an additional testing level and give more assurance to the new system.

Phased is when the new system is rolled out in ‘phases’ – such as regions – the advantage might be that trainers can travel from region to region (without having all training taking place at the same time) – and that the burden on help desk personnel might also be lighter.

Reference: Selecting the Conversion Strategy Difficulty: medium 61. What is a ‘business contingency plan’? What is its purpose?

Answer Business contingency plans are to keep small technology glitches from turning into major disasters. There are many examples of how major financial losses have occurred with major system changes (like Hewlett-Packard and Nike with SAP installation). Business disasters are prevented with good project management and migration planning. Parallel conversion is one approach to contingency planning – as a system that is known will still be available when the new system is turned on. The worst-case scenario is to not have any system at all!!!

62. What is the most technically complicated step in the migration plan? Why? Answer Data conversion is generally considered the most technically complicated step in the migration.

The data might be in an older ‘legacy’ format and needs to be converted to a database format.

The files in the old system may not match the files and databases in the new systems.

Reference: Preparing the Technology Difficulty: medium 63. In motivating users to adopt a new system, it is suggested that change agents develop two clear and concise lists of costs and benefits provided by the new system as compared to the as-is system. Why is this important?

Answer The costs and benefits from the new system should come from the original system request. This set of organizational costs and benefits should be distributed widely so that everyone expected to adopt the new system clearly understands why the new system is valuable to the organization.

These also need to be looked at from the employee’s perspective. A change that is good to the organization may not be beneficial to the individual employee. For example, changing from hand-written address labels in the mailing room to computer created address labels might mean that the mail room employee has more work to do. All change is made by individuals, not organizations. Compelling reasons need to be made to key groups to help convince them to adopt the new system.

Reference: Assessing Costs and Benefits Difficulty: medium 64. What are the two basic strategies to motivate adoption? Give information on each.

Answer Informational and political. Information strategies are to convince potential adopters that the changes are for the better by demonstrating more benefits than costs. This will be widely distributed. Political strategy uses organizational power to motivate change – and probably comes from higher up in the organization “adopt or you are fired” – “adopt or you will be reassigned to a lower paying job”, etc.

65. How can careful training help adoption of a new system?

Answer From the chapter, “Training is probably the most self-evident part of any change management initiative. How can an organization expects its staff members to adopt a new system if they are not trained?” Every new system requires new skills – sometimes subtle and sometimes major changes. Training should focus on how to help the users accomplish their jobs.

Reference: Enabling Adoption: Training Difficulty: medium

66. What happens after the project team has installed the system and performed the change management activities? What happens to the system from that point on?

Answer The system is officially turned over to the operations group. There will probably be a help desk to support ongoing questions and issues; there may be a ‘frequently asked questions (FAQ)’ website and continuing support functions.
