4. 4 Your Response per Napoleon  “Any commander in chief [software engineering manager] who undertakes to carry out a plan which he considers defective is at fault; he must put forth his reasons, insist on the plan being changed, and finally tender his resignation rather than be the instrument of his army’s [project team’s] downfall.”

5. 5 How to Change an Unrealistic Deadline  Perform a detailed estimate of effort and time using historical data  Using an incremental process model, develop a strategy to deliver critical functionality by the deadline – document the plan  Meet with the customer and explain why the  Offer the incremental development strategy as an alternative  Perform a detailed estimate of effort and time using historical data  Using an incremental process model, develop a strategy to deliver critical functionality by the deadline – document the plan  Meet with the customer and explain why the  Offer the incremental development strategy as an alternative

18. 18 Earned Value Analysis (EVA)  Earned value  is a measure of progress  enables us to assess the “percent of completeness” of a project using quantitative analysis rather than rely on a gut feeling  “provides accurate and reliable readings of performance from as early as 15 percent into the project.” [FLE98]  Earned value  is a measure of progress  enables us to assess the “percent of completeness” of a project using quantitative analysis rather than rely on a gut feeling  “provides accurate and reliable readings of performance from as early as 15 percent into the project.” [FLE98]

19. 19 Computing Earned Value-I  The budgeted cost of work scheduled (BCWS) is determined for each work task represented in the schedule.  BCWS i is the effort planned for work task i.  To determine progress at a given point along the project schedule, the value of BCWS is the sum of the BCWS i values for all work tasks that should have been completed by that point in time on the project schedule.  The BCWS values for all work tasks are summed to derive the budget at completion, BAC. Hence,  BAC = ∑ (BCWS k ) for all tasks k  The budgeted cost of work scheduled (BCWS) is determined for each work task represented in the schedule.  BCWS i is the effort planned for work task i.  To determine progress at a given point along the project schedule, the value of BCWS is the sum of the BCWS i values for all work tasks that should have been completed by that point in time on the project schedule.  The BCWS values for all work tasks are summed to derive the budget at completion, BAC. Hence,  BAC = ∑ (BCWS k ) for all tasks k

20. 20 Computing Earned Value-II  Next, the value for budgeted cost of work performed (BCWP) is computed.  The value for BCWP is the sum of the BCWS values for all work tasks that have actually been completed by a point in time on the project schedule.  “the distinction between the BCWS and the BCWP is that the former represents the budget of the activities that were planned to be completed and the latter represents the budget of the activities that actually were completed.” [WIL99]  Given values for BCWS, BAC, and BCWP, important progress indicators can be computed:  Schedule performance index, SPI = BCWP/BCWS  Schedule variance, SV = BCWP – BCWS  SPI is an indication of the efficiency with which the project is utilizing scheduled resources.  Next, the value for budgeted cost of work performed (BCWP) is computed.  The value for BCWP is the sum of the BCWS values for all work tasks that have actually been completed by a point in time on the project schedule.  “the distinction between the BCWS and the BCWP is that the former represents the budget of the activities that were planned to be completed and the latter represents the budget of the activities that actually were completed.” [WIL99]  Given values for BCWS, BAC, and BCWP, important progress indicators can be computed:  Schedule performance index, SPI = BCWP/BCWS  Schedule variance, SV = BCWP – BCWS  SPI is an indication of the efficiency with which the project is utilizing scheduled resources.

21. 21 Computing Earned Value-III  Percent scheduled for completion = BCWS/BAC  provides an indication of the percentage of work that should have been completed by time t.  Percent complete = BCWP/BAC  provides a quantitative indication of the percent of completeness of the project at a given point in time, t.  Actual cost of work performed, ACWP, is the sum of the effort actually expended on work tasks that have been completed by a point in time on the project schedule. It is then possible to compute  Cost performance index, CPI = BCWP/ACWP  Cost variance, CV = BCWP – ACWP  Percent scheduled for completion = BCWS/BAC  provides an indication of the percentage of work that should have been completed by time t.  Percent complete = BCWP/BAC  provides a quantitative indication of the percent of completeness of the project at a given point in time, t.  Actual cost of work performed, ACWP, is the sum of the effort actually expended on work tasks that have been completed by a point in time on the project schedule.

22. 22 Problem 24.12 Assume you are a software project manager and that you’ve been asked to computer earned value statistics for a small software project. The project has 56 planned work tasks that are estimated to require 582 person-days to complete. At the time that you’ve been asked to do the earned value analysis, 12 tasks have been completed. However, the project schedule indicates that 15 tasks should have been completed. The following scheduling data (in person-days) are available:

34. 34 Risk Projection  Risk projection, also called risk estimation, attempts to rate each risk in two ways  the likelihood or probability that the risk is real  the consequences of the problems associated with the risk, should it occur.  The are four risk projection steps:  establish a scale that reflects the perceived likelihood of a risk  delineate the consequences of the risk  estimate the impact of the risk on the project and the product,  note the overall accuracy of the risk projection so that there will be no misunderstandings.  Risk projection, also called risk estimation, attempts to rate each risk in two ways  the likelihood or probability that the risk is real  the consequences of the problems associated with the risk, should it occur.  The are four risk projection steps:  establish a scale that reflects the perceived likelihood of a risk  delineate the consequences of the risk  estimate the impact of the risk on the project and the product,  note the overall accuracy of the risk projection so that there will be no misunderstandings.

36. 36 Building the Risk Table  Estimate the probability of occurrence  Estimate the impact on the project on a scale of 1 to 5, where  1 = low impact on project success  5 = catastrophic impact on project success  sort the table by probability and impact  Estimate the probability of occurrence  Estimate the impact on the project on a scale of 1 to 5, where  1 = low impact on project success  5 = catastrophic impact on project success  sort the table by probability and impact

37. 37 Risk Exposure (Impact) The overall risk exposure, RE, is determined using the following relationship [HAL98]: RE = P x C where P is the probability of occurrence for a risk, and C is the cost to the project should the risk occur.

38. 38 Risk Exposure Example  Risk identification. Only 70 percent of the software components scheduled for reuse will, in fact, be integrated into the application. The remaining functionality will have to be custom developed.  Risk probability. 80% (likely).  Risk impact. 60 reusable software components were planned. If only 70 percent can be used, 18 components would have to be developed from scratch (in addition to other custom software that has been scheduled for development). Since the average component is 100 LOC and local data indicate that the software engineering cost for each LOC is $14.00, the overall cost (impact) to develop the components would be 18 x 100 x 14 = $25,200.  Risk exposure. RE = 0.80 x 25,200 ~ $20,200.  Risk identification. Only 70 percent of the software components scheduled for reuse will, in fact, be integrated into the application.
