Measurement & metrics

Measurement is essential for planning, executing, and evaluating software projects successfully. It helps set achievable targets and monitor progress to determine if corrective action is needed. Historical measurement data from past projects provides the basis for estimating targets and plans for new projects. During project execution, measurement allows managers to track actual performance against plans and identify issues requiring attention, such as ensuring quality targets will be met or focusing reviews on certain modules. Root cause analysis of measurement data also helps organizations understand problems and prioritize process improvements.
Measurement & metrics
- 2. Measurement is essential for planning and executing projects successfully. Helps to establish targets towards which the project team works. Measurement -determine whether the progress of the project is satisfactory and whether corrective action is required.
- 3. Measurement provides a mechanism for objective evaluation. if you want your actions to be correct and successful, you should base them on data that assists in decision-making.
- 4. A software project is considered successful if it: Is executed within the budgeted cost Is completed within the scheduled time Produces a good-quality product How can measurement contribute to project success? To understand how measurement can contribute to project success, think about how the project manager and the stakeholders can set targets and monitor project performance.
- 5. For successful execution of a project, the targets should be achievable and there should be a plan to achieve these targets. Measurement data from past projects is used to estimate and set achievable targets for the project cost, schedule, and quality. Measurement helps a project manager to monitor and control the project by tracking the actual performance.
- 6. It provides data on the status of activities, resource utilization, and the technical quality of the work done. The actual performance is checked against the plans on an ongoing basis so that corrective action can be taken where necessary. The data gathered across projects can be used for analysis to decide on how to refine software processes.
- 8. Measurement can be used to understand the characteristics of the s/w process. For example, you can use measurement to understand the productivity and defect rate that can be expected if the process is followed. The data obtained by measuring past projects gives a basis for predicting what can be expected in future projects and thereby helps in more accurate estimation. Consider the differences between the characteristics of past projects and the one being estimated. Achievable targets for the project cost, schedule, and quality can be established by using the available historical data
- 10. In the absence of data from old projects, other data should be used for estimation, such as industry data for similar projects. We can also use available estimation models that have been calibrated using relevant industry data. Essentially, estimation, the first step of project planning, is based on an analysis of the available historic data or models that have been based on analysis or industry data.
- 12. Measurement was used to evaluate the status and identify whether corrective action was needed. In a software project, the success of a project is seen in terms of working within the budget, meeting the schedule, and producing good quality. Achievable targets are set, and a plan is made to meet them. Projects are then executed according to the plan. Which aspects of measurement, in the context of project monitoring and control, are of concern to the project manager during the execution stage?.

- 16. Root cause analysis of data helps to answer questions such as: Which types of errors occur more often and why? Why is the quality of the product low? Why are projects always late? Such analysis helps to decide the priorities for software process improvement at the organization level and check the effectiveness of improvement efforts. Software project managers benefit from improved software processes in their subsequent projects.
