Without measuring these, a project cant be completed successfully. Project metrics are the metrics used by the project manager to check the projects progress. Software testing metrics or software test measurement is the quantitative indication of extent, capacity, dimension, amount or size of some attribute of a process or product. It is important to note that if metrics are used punitively, these goals are hampered and the team psychological safety could be at risk. Software metrics are important for many reasons, including measuring software performance, planning work items, measuring productivity, and many other uses within the software development process, there are many metrics that are all related to each other.

Project metrics are a very efficient way to assess the health of a project and make informed decisions. These metrics enable management to understand the quality of the software, the productivity of the development team, code complexity, customer satisfaction, agile process, and operational metrics. Analyze the cost benefits aspect of each metrics and the project lifestyle phase in which it results in the maximum output. Even if a metric is not a measurement metrics are functions, while measurements are the numbers obtained by the application of metrics, often the two terms are used as synonyms. Project technical managers who must plan, motivate, organize, and control the practitioners who do software work. Our analytics and product teams partnered on this project from idea right through to launch.

A software metric is a measure of software characteristics which are quantifiable or countable. These values have to be assessed correctly otherwise they will not give accurate measurements and can lead to false estimations, etc. Metrics in project management by crystal lee, pmp metrics may not be the sexiest subject in project management, but the success of the project management office pmo you work in, indeed, perhaps your job as a project manager, may be dependent on whether you have a metrics program in place.
