Test Metrics Analysis and Decisions (TMAD) Model Metrics Analysis Proposed Metrics

Defect Containment Effectiveness

Goal

1. Improve testing quality 2. Prevent defect leakage

Associated Queries (RCA)

Undesired Behaviour (Risks)

1. Was the criteria to classify defect detection phase clear from a leakage perspective? 2. Are there clear entry and exit criteria between phases 3. Was the team's knowledge adequate to uncover leaked defects? 4. Was the scope of testing for each phase clear? 5. Do we have requirement traceability matrix?

1. Blame game 2. Manipulation of defect classification criteria

Metrics Decision Table Decision Support (Scope) 1. 1. Improve test case review effectiveness 2. Improve process compliance 3. Improve product and test design knowledge

Corrective Actions (feedback) Clear entry and exit criteria between phases Process adherence Effective knowledge management Update test suite Get test strategy reviewed by customers

Raw Data Requirements

1. Defects detected in test phase 2. Leaked defects

Suggestions

Do RCA for every release and identify preventive actions

Slide 8


Test Quality Index (TQI) Model

● Bivalent questionnaire; Y or N

1

Identify areas of improvement

responses

● “Productivity per tester” vs.

“quality of deployed resources and resource deployment”

● Contextual metrics vs.

comprehensive score; across 30 process areas

3

Improve scores with each deliverable

2

Customize the scored checklist

● Scoring based on self assessment

Case Study The Customer

Business Impact • 90% coverage on test cases executed, a significant improvement over the earlier metric

The customer is the world's leading specialist in air transport communications and information technology (IT) solutions.

The Business Challenge • No testing guidelines • Inadequate process • Lack of measures for impact of testing • No single snapshot of engagement level governance

100% achievement on acceptable open defects for severity 1 and 2

• •

Customer overhead of test case reviews reduced by 60% Constant review of the test case execution helped us to evaluate and report how far/near is the application from the acceptance criteria at different phases of testing

Enabled development team to prioritize the defects that needs to be fixed for the immediate build

Customer is now able to ascertain the quality of the application

Reduced risks and enabled effective decision making through test dashboard

MindTree Solution Executed in-depth analysis to understand

Quality objectives and alignment between test process and application's business goals

Used Test Metrics Analysis and Decisions (TMAD) Model and Test Quality Index (TQI) to come up with appropriate metrics and processes

“MindTree's expertise in metrics is paramount in managing the engagement and seeing if process changes have made the hoped for improvement and if the application is ready for release. The metrics are also a great way to communicate progress across all the groups in this engagement.”

Collected key metrics as governance enablers to measure and drive decisions based on the health of the projects
