System optimisation - Study guides, Revision notes & Summaries

Software testing is one of the main activities of software development life cycle (SDLC). More than 50% of the total cost of the project is consumed in software testing phase of SDLC (Beizer, 1990). The main aim of software testing is to produce better quality and reliable software. Broadly, software testing is of two types, white box testing and black box testing. Among the two test approaches towards software testing, white box testing is the preferred one owing to its ability to rec...

IOP2603 Study Unit 1 Introduction to Human Factors and Ergonomics Ergonomics = work + laws. The primary purpose of human factors and ergonomics is design. In designing a workplace, the existing situation must first be analysed, new design solutions must be synthesised, and these design solutions must be analysed again. Interdisciplinary system goals; 1. To formulate system goals. 2. To understand functional requirements. 3. To design a new system. 4. To analyse a system. 5. To implem...
