Figure. 1. Knowledge area classification [5]
PSP & XP
PSP covers different competency areas, and each competency area further
classifies into knowledge areas, as mentioned in Fig. 1. Agile software
development can state many specific software development methods, the
best known Scrum and XP [5]. XP is a lightweight, agile, rebates,
and methodology for developers 2 to 10 [6]. A set of XP has
established principles and practices values [7]. The advantages of
using the XP process model include faster time to market, form a more
in-depth, more motivated development team’s customer satisfaction, and
honored [8].
The Need for Systematicaly Mapping
In this study, methodical mapping has investigated to discover issues
that are looked at during the estimation of a person’s exhibition
[57]. the quality standards of PSP were investigated during
methodical mapping, that can be utilized for a person’s exhibition
estimation in a coordinated group [58].
High-development improvement forms, utilizing measurements and
quantitative strategies, for example, the PSP can create a lot of
information to distinguish execution issues [28].One collective
blame of software engineering occupation is the weak value of products
that software engineer harvests[37]. The uses of PSP notions and
procedures in their effort, engineers in nearly any technical area can
increase their planning abilities, the value of their work, and decrease
the number of faults in their yields[41] since PSP trusts profoundly
on the group and analysis of private data as evidence of effective
procedure execution[49]. The necessary concepts’ descriptions and
PSP’s services can help the software specialists in evaluating their own
abilities and services and in classifying areas in which they need of
enhancement [4].
