The traditional approach to determine material requirements is to monitor inventories constantly; whenever they fall to a predetermined level, a preset order is placed to replenish them. This traditional approach (involving re-order levels and economic order quantity calculations) originates in the pre-computer era. A manufacturing resource planning system is a fully integrated computerised planning approach to the management of all the companyâ&#x20AC;&#x2122;s manufacturing resources including inventory, labour and machine capacity. It seeks to ensure that resources are available just before they are needed by the next stage of production or despatch. It also seeks to ensure that resources are delivered only when required so that raw material inventory is kept to a minimum. The technique enables managers to track orders through the manufacturing process and helps the purchasing and production control departments to move the right amount of material or sub-assemblies at the right time to the right place. The current inventory management system relies on the assumption that there is constant demand. An MRP system begins with the setting of a master production schedule specifying both the timing and quantity demanded of each of the finished goods items and then works backwards to determine the resource requirements at each stage of the production process. It aims to generate a planned schedule of materials requirements after taking account of scheduled receipts, projected inventory levels and items already allocated to production. The EOQ model can be used within MRP provided that the major assumption in the EOQ model of constant demand applies.


Under an activity based budgeting (ABB) system, resource allocation is linked to the strategic plan and is prepared after considering alternative strategies. This approach ensures that new activities that are required to meet the companyâ&#x20AC;&#x2122;s strategic objectives are included in the budget. Under a traditional incremental budgeting system the focus is on existing resources and operations. Adjustments are then made for changes in activity and price which results in past inefficiencies being perpetuated. Under an activity based budgeting system, only resources that are needed to perform activities required to meet the budgeted production and sales volumes are included. Activity based techniques including activity based budgeting focus on the outputs of a process rather than the input to the process. This approach provides a clear framework for understanding the link between costs and the level of activity. It allows the ranking of activities and the determination of how limited resources should be allocated across competing activities. Traditional budgeting systems present costs under functional headings i.e. the emphasis is on the nature of the cost. The weakness of this approach is that it gives little indication of the link between the level of activity and the cost incurred. The approach under a traditional system is to make arbitrary cuts in order to meet overall financial targets. Activity based budgeting allows the identification of value added and non-value added activities and ensures that cuts are made to non-value added activities. ABB is also useful for review of capacity utilisation. If it is known that the resources devoted to a particular activity are greater than those currently required then these resources can be reduced or redeployed.

(b) Examinerâ&#x20AC;&#x2122;s note: the question asks for three reasons. Examples of points that would be rewarded are given below. In a JIT environment measuring standard costing variances may encourage dysfunctional behaviour. A JIT production environment relies on producing small batch sizes economically by reducing set up times. Performance measures that benefit from large batch sizes or producing for inventory should therefore be avoided. In an AMT environment the major costs are those related to the production facility rather than production volume related costs such as materials and labour which standard costing is essentially designed to plan and control. Fixed overhead variances donâ&#x20AC;&#x2122;t necessarily reflect under or overspending but may simply reflect differences in production volume. An activity based cost management system may be more appropriate, focusing on the activities that drive the cost. In a total quality environment, standard costing variance measurement places an emphasis on cost control to the detriment of quality. Cost control may be achieved at the expense of quality and competitive advantage. A continuous improvement environment requires a continual effort to do things better rather than achieve an arbitrary standard based on prescribed or assumed conditions. In todayâ&#x20AC;&#x2122;s competitive environment cost is market driven and is subject to considerable downward pressure. Cost management must consist of both cost maintenance and continuous cost improvement. In a JIT/AMT/TQM environment the workforce is usually organised into empowered, multiskilled teams controlling operations autonomously. The feedback they require is real time. Periodic financial reports are neither meaningful nor timely enough to facilitate appropriate control action.

(b) The NPV is the amount by which the present value of the future cash flows exceeds the initial outlay. The cash flows are discounted at the rate that reflects the alternative use of the funds, normally the company’s cost of capital. Investment decisions should be based on NPV since it is the only appraisal method that will ensure the maximisation of shareholders’ wealth. If the decision is based on NPV then either Project B or C should be undertaken. However NPV does not indicate the range of outcomes that may result. While Project A has a lower expected NPV the standard deviation of Project A is also lower and depending on the company’s attitude to risk they may decide to undertake Project A. The standard deviation is a measure of risk. It compares all the possible outcomes with the expected value (or mean outcome). Project B and C have the same NPV therefore it is possible to directly compare the standard deviations. The standard deviation for Project C is lower than that for Project B which means that the outcomes for Project C have less variability. Since Project A has a lower NPV than Project B and Project C it is necessary to calculate the coefficient of variation. The coefficient of variation for Project A and Project C is 6·67% and 16·67% respectively. Therefore, in terms of achieving the expected net present value, Project A is less risky than Project C. We would need however to see the range of possible outcomes since in this case it is the risk of outcomes below the expected outcome that is important. There is however a trade-off between risk and return. The higher the risk, the higher the potential return. The decision on which project to undertake will depend on the managing director’s attitude to risk. If the Managing Director is risk averse he would choose Project A. If he is risk seeking he would choose Project B as it has the potential for higher returns. The IRR is the rate of return that equates the present value of future cash flows with the initial outlay. It is the discount rate that will result in a net present value of zero. Project C has the lowest IRR, however as stated above investment decisions should be based on NPV. A limitation of Net Present Value is that it does not consider the life of the project. The longer the project the more uncertain the cash flows are likely to be. The payback method of investment appraisal determines how long it takes for the project to payback its initial investment. It therefore to a certain extent copes with an uncertain future by placing more emphasis on early cash flows.
