Project Quality is one of three key constraints involved into so called “Project Triangle” including matters of Costs, Time and Quality. The point of a triangle analogy is to show that interrelations between Costs, Time and Quality are so strong that you cannot change one matter without affecting the two others. In fact, the Project Quality is a set of different standards and objectives that are embedded into complex success criteria utilized by project customers to accept the project results. Project Quality is a definition of requirements demanded by the project customers, and they refer to description of:
- Relative worth of the project results which the customers expect to obtain at certain costs;
- Utility of project results measured by specific needs and vision of the project customer;
- Excellence of performance in terms of proficiency, diligence and other working attitudes;
The project quality is regulated by the Project Quality Plan. There are different methodologies to ensure a proper level of quality throughout the whole project lifecycle. The four main processes that are continuously maintained during the project development and execution make up together a sole discipline called the Project Quality Management. These four processes are: the quality planning, quality control, quality assurance and quality improvement. Project Quality Management is focused not only on measuring quality of results or products, but it controls all aspects of business processes and productive means used at the project (defective processes cannot produce high-quality results).
