- 3. PROJECT TRACKING • Let us examine the basic project tracking at Infosys. • Once a detailed project plan is made which consist of all details of project such as start date & end date, and people assign for project. • At least project manager must track the execution of these task. • That endeavour constitutes activity tracking. • The project manager must track the unresolved issues that crop up & the defect that are detected. • The outcome is captured in a status report, which is also distributed to the senior management.
- 4. ACTIVITIES TRACKING • The basic task in project tracking is to ensure that planned activities are done on time. • At Infosys the activities are scheduled using Microsoft Project(MSP). It is also used for project tracking. • The project manger checks the status of the schedule task and updates the status in MSP. • When the activity is finished it is marked 100% in MSP. • MSP provide the feature to track the status of individual task . • A project manger can determine which higher level task are lagging behind, what percentage of task has been done. • Based on the activities completed ,actual time they took, the project manager reschedule the remaining task.
- 5. DEFECT TRACKING • Infosys uses a defect control system for tracking control. • Once information is entered in this system, it remains open until it has been fixed. • The defect is marked as close when its removal has been verified. • In this way each defect is logged and tracked to closure. • Sometimes, project managers track the state of a defect by recording the date of submission & the date of closure for each defect. • The project manager can check the overall defect injection & defect closure, information about gap between the defects submitted and the number of defect is in control.
- 7. ISSUE TRACKING • Inevitably, many small jobs or clarification come up during a project. These problem are called issues. • Managing issue is an important task for any project manager because they can be numerous & can potentially delay a project. • To solve such kind of problem there is a provision of using a issue log. • All the issues are recorded as they arise, along with related information. • When the issue are closed they are marked as close. • The project manger use a spreadsheet, maintain document, use issue tracker utility, or use the defect tracking system.
- 9. STATUS REPORT • Status report are the main mechanism for regularly communicating the state of project to senior management and the customer. • The party who receive status report are specified in the project management plan. • Status report are generated weekly & contain these items. • Customer complain. • Milestone achieve this week. • Milestone missed this week and the reason for them. • Milestone planned for the next week. • Issues requiring clarification or attention. • Escalation, if any • Estimated work versus available time by milestone.

- 11. ACTIVITY LEVEL ANALYSIS USING SPC • To provide finer control, activity-level analysis is also done at Infosys. • In activity-level analysis, some metrics are analyzed immediately after a task is performed. • The analysis is used to evaluate the effectiveness of the task performance. • If the task has not been performed satisfactorily, immediate action can be taken to correct it and to prevent a repetition. • Activity-level analysis is usually done using statistical process control (SPC).
- 12. SPC ANALYSIS • At Infosys, reviews and unit testing have been identified as the two tasks for which SPC is applied. • Using control charts, the project manager immediately evaluates the effectiveness of a review or a unit test. • If the performance is not satisfactory, necessary action can be taken. • The focus of activity-level monitoring is on the coding-related activities of reviews and unit testing. • Activity-level monitoring and control of unit testing the other activity for which SPC is applied.
- 13. CONTINUED • The guidelines given earlier for testing can be used to decide which actions are needed (for analysis, project managers can use supporting information about effort spent on the task, effort expended on previous tasks, and defects found). • Figure shows the control chart for defect density for unit testing of one programming language. • The defect density can be plotted in terms of the number of defects per LOC or the number of defects per person-hour.

- 16. CONCLUSION • As with reviews, project managers can use the SPC tool to implement activity-level control of unit testing. • This tool contains relevant past performance data such as the defect injection rate, the defect removal percentage, and so on. • Using this data, it determines the control limits as well as expected limits. • When the performance data of a unit test is entered, the tool immediately tells whether or not the performance is outside the limits.
