It provides customer value and meets the product owner's specifications. 37-70, (1995). Size and complexity of software. When team members contribute effectively and remain motivated during development process would cause high quality and productivity results. 1. Why do development teams use metrics to measure quality? The productivity measure has become a tool for managers since it is used to compare the performance between different companies (benchmarking) and to compare the efficiency of different developers in the same company.

Perhaps the most notable methodology that is being supported by these automated tools is the structured methodology and its many variants. 2. Software organizations need to increase their productivity to stay competitive. Although its earliest measurement was in lines of code per man-hours worked, a better definition is the ratio between the functional value of software produced to the labor and expense of producing it. CASE Productivity PErceptions of Software Engineering Professionals As we move closer to the 1990s, business and scientific software engineering workbench tools are becoming a pervasive market commodity.

Quality is a customer determination, not an engineer's determination, not a marketing determination, nor a general management determination. 12.9 Techniques to help Enhance software Quality So far in this chapter we have looked at the steps a customer might take to ensure the quality of software produced by an outside supplier Increase Visibility: A landmark in this movement towards making the software development process more visible was the advocacy by the American software guru, Gerald Weinberg of egoless programming. Product revision factors− Maintainability, Flexibility, Testability. For software products, the fitness of use is generally explained in terms of satisfaction of the requirements laid down in the SRS document. ARTICLE . Answer: - Quality of software may be defined as the need of function and Efficiency. External quality is the usefulness of the system as perceived from outside. This quality can be measured through feature tests, QA and customer feedback. Flexibility is the ability of software to add/modify/remove functionality without damaging the current system. 2.
