The PSPSM delivers engineers with a well-organized individual framework
to do work[1]. The PSP delivers a way to software engineers to
advance the value, productivity, and probability of their work[2] .
PSP aimed to report the enhancement of the needs of different engineers.
This encourages designers to comprehend the nature of their work and to
welcome the adequacy of the strategies they use [2]. PSP was
presented by Watts Humphrey as ”A Castigation” for Software Engineering
[1]. The PSP process comprises a set of methods, script, and forms
that provides a structured approach to individuals to plan and manage
their work[2]. The PSP [3] is a controlled structure by which
programming designers can design, track, and manage faults earlier to
harvest good quality products[3] [1]. The main objective is to
produce a quality product with a zero-defect product when individuals
use PSP [2]. There are a lot of discrepancies found in the
traditional model; a new model “Agile” was presented to cater to
traditional model problems [4]. The PSP [3] is a planned context
by which individual engineers to plan, track, and accomplish faults
earlier to produce high quality products [1]. Data Collection and
analysis is evidence of nominal process implementation in PSP[3].
A novel process called ”Agile” and went on to overcome problems with
conventional ways [3]. The traditional approach to a different way
of adoption. For frequent are the methodologies under the canopy of
”Agile” is more than a standard methodology extreme Programming (XP). A
set of ideals and XP values and a deep, quickly develop software that
offers quality is perfect competition. Russell Oberlin programming (XP)
is lightweight, agile methods to the elastic developers 2 to 10
[15]. They are founded on a set of beliefs, XP nearby principles,
values, and practices [16]. Principles are concepts defined to a
high level, while these practices are that in the steps taken by the
values [16]. Value to the troops bears responsibility values
practices. The principles have been the gap between the practical
values and a set of rules and practices used to describe the value’s
victory [17]. Value has five XP, communication, leisure, feedback,
and a resolution to the resection [16] [17] the twelve practices
[18]. Advantages of XP and a faster processor that includes software
development, better quality, better customer satisfaction, and highly
respected development teams motivated [19].
