Literature & Background Knowledge

The PSP was presented by Watts Humphrey as ”A Discipline” for Software Engineers [1] and a controlled structure by which programming specialists can plan, follow and oversee deserts prior to deliver top notch products[1]. Enhancements in hierarchical execution could likewise result from process improvement by singular designers. Humphrey perceived that an association arrives at a development level past which hierarchical procedure improvement requires singular procedure improvement. Level0 is mainly the present process the individual engineer practice to write programs and software and to provide performance measurements. PSP level0 was improved to Level 0.1 by the addition of size measurement, coding standard, and personal process improvement. Level 0.1 also improves package size capacity, individually count procedures and methods. After Level 0.1, Level 1.0 enhances planning to Level 0, and the early step adds size and reserve estimation. In Level 1.1, planning and status tracking are introduced. In Level 2, a wide-ranging and constant emphasis is sited on refining the individual’s capability to quality program production. The main objective is to produce quality work in a consistent way. The intent of introducing Level 2.1 is not to provide a designing process but to tell engineers how to state the criteria for design accomplishment. The Level 3 process presents methods for individuals to developing large scale programs[9].
