Analysis of RUP and Scrum Methodologies for Software Development

This report provides a comparative analysis of two prominent software development methodologies: Rational Unified Process (RUP) and Scrum. It begins by outlining the purpose of the study, which is to identify the most effective methodology for software development, particularly for companies like Innovative Solutions. The report delves into the specifics of each methodology, detailing the phases of RUP (Inception, Elaboration, Construction, and Transition) and the iterative, agile nature of Scrum. It highlights the advantages and disadvantages of both approaches, such as RUP's structured framework and Scrum's flexibility. A comparison table further contrasts the two, focusing on aspects like methodology, sequence, scope, artifacts, and timeline. The report concludes with selection guidelines and recommendations, suggesting that Innovative Solutions consider adopting Scrum for its ability to facilitate frequent prototyping and incremental development, while also emphasizing the importance of adapting the methodology to project needs rather than the other way around. The report uses multiple sources and references to support the analysis.

INTRODUCTION
Purpose of the study
In staying viable in the current market and advance market share, software development
corporations need to supply high-quality yields that meet or exceed clients’ expectations within
budget and programme. For this purpose, Innovative Solutions are continually looking for
conducts to improve their software development course. The purpose of the report is identifying
the best methodology recommended applying. The report gives information about various
software development methodologies that should be of great advantage to small and large
businesses. Presently, there are many software methodologies from which to choose, but in our
case, we will look just two of them; Rational Unified Process and Scrum. Both have strengths
and faintness because they focus on diverse facets of the software development life cycle
(SDLC). As a result, some academics and consultants have proposed several hybrid approaches
combining two or more software procedures with the resolution of leveraging relevant strengths
thereby enlightening the entire development progression (Acosta, Espinosa & Espinosa 2018,
p98).
SYSTEM DEVELOPMENT METHODOLOGIES
Rational unified process (RUP)
Rational Unified Process (RUP) is a software development procedure from Rational, an IBM
detachment that splits the development process into four different phases where each involves
occupational modeling, analysis and design, execution, testing, and utilization. RUP is an
iterative software development course framework generated by the Rational Software Company,

an IBM dissection since the year 2003. RUP is not a single concrete unbending process, but
relatively an adaptable procedure framework, envisioned to be tailored by the expansion
organizations and software project players that will choose the basics of the process that are
suitable for their requirements. According to (Kruchten 2004, p98) RUP is a detailed
implementation of the Incorporated Process. The four segments are:
• Inception – This where the project idea is specified. The development squad determines if the
development is worth tailing and what assets/capitals are needed.
• Elaboration - The project's style and required resources are extra evaluated in this phase.
Developers consider likely applications of the software and prices associated with the expansion.
• Construction - The scheme is developed and accomplished where the software is designed,
transcribed, and verified.
• Transition – The phase where software is unconfined to the public and final modifications or
updates are made grounded to the end users feedback.
The RUP growth methodology provides an organized way for companies to envisage create
software programs. Since it delivers a specific plan for each phase of the development
progression, it aids in preventing resources from being misused and reduces unanticipated
development costs (Kuhlen & Speck 2017, p87).
Advantages
• Permits for the adaptive competence to deal with varying requirements throughout the
lifecycle (development), whether they arise from clients or from within the venture itself.
• Emphasizes the necessity (and proper enactment of) accurate certification.

NETWORKING 5
Disadvantages
• Comprehensively relies on capable and expert team associates, since the task of deeds to
individual workers requires the production of tangible, pre-planned outcomes in the form of
relics.
• Given the importance on integration through the development procedure, this can also be
disadvantageous during testing or other stages, where incorporations are conflicting and getting
in the technique of other, more important activities (Usman et al. 2014).
Scrum
Scrum is an agile outline for managing exertion with prominence in software development. It is
intended for development players from three to nine affiliates breaking their tasks into actions
that can be finalized within time sparred restatements and track growth and re-plan in 15-minute
stand-up conferences, referred to as daily scrums. Scrum is an incremental and iterative context
for handling product development. It describes a supple, holistic product development approach
where an expansion team works as a component to reach a mutual goal. With its segmental,
incremental, concerted approach, scrum is quick and extremely adaptive to varying needs and
competitive contests that is why it has so several advocates (Aljawarneh, Alawneh, & Jaradat
2017, p45).
Advantages
• Scrum procedure allows projects where the occupational requirements certification is hard to
enumerate to be successfully established.
• Fast stirring, cutting-edge growths can be rapidly coded and tested using the scrum where
arising mistakes can be easily remedied.

• It is an informally controlled technique that insists on recurrent updating of the growth in
work through regular assemblies. Thus there is pure visibility of the scheme development.
Disadvantages
• Scrum is one of the foremost causes of scope sidle since unless there is a specific end date,
the scheme management shareholders will be attracted to keep demanding that fresh
functionality is distributed (Stoica, Mircea & Ghilic-Micu 2013, p17).
• If a mission is not well demarcated, estimating venture costs and time tends to be incorrect. In
such a case, the duty can be spread over numerous dashes.
• If the squad members are not dedicated, the project will either not ever complete or will flop.
Comparison of scrum and RUP processes
Both procedures are pain staked to be Agile and method project activities in the iterative
technique. Both the Rational Unified Process (RUP) and Scrum are software frameworks
(development). They are considered to be responsive, which means that the necessities and
resolutions of the project progress as a result of team association (Mousaei & Gandomani 2018,
p43). They also together apply an iterative tactic, splitting the expansion process into
idiosyncratic stages. Both outlines underline cross-functionality and partnership and promote
self-management within the squad. And finally, there is an emphasis on product excellence
within both contexts. Though RUP methodology calls for a proper definition of space and major
project signposts are associated with exact dates, scrum methodology applies project surfeit
instead of a scope and permits the backlog to be redefined at the close of each iteration
(frequently about every four weeks). In accumulation, RUP segments the project lifespan into
four major chapters as described in the report above. Even though it inspires concurrent
workflows crosswise the entire cycle, the universal understanding is that certain deeds will top
6

NETWORKING 7
during certain stages. On the divergent, SCRUM decrees that the entire outmoded lifespan fits
into one restatement. In other words, a capability for one iteration of a spell is recognized, and
then the complete cycle happens within one iteration (Leau et al. 2012).
Comparison table
RUP SCRUM
Methodology Iterative Iterative
Sequence Prescribed Cycle is defined across four
phases, but some workflows can be
synchronized.
Each dash (iteration) is a
comprehensive cycle.
Planning Prescribed project plan, related with
multiple recapitulations, is utilized. The
idea is end-date determined and also has
midway milestones.
No end-to-end scheme plan. Each
subsequent iteration plan is
enhanced at the end of the present
iteration (NOT end-date driven).
Product Owner determines when
the task is done and to be
completed.
Scope The scope is demarcated ahead of the
scheme start and documented in the range
document. The scope can be reread during
the project, as necessities are being
elucidated, but these amendments are
subject to a sternly controlled process.
In its place of scope, SCRUM
applies a Project Backlog that is re-
evaluated at the completion of each
sprint.

Selection guidelines and Recommendations
Both developments have their remunerations and drawbacks that go together with active
development in several businesses. The business to have successful software development has
7

NETWORKING 8
been appreciative to both progressions in depth and yield the segments of each that are
unsurpassed suited to the specific product and setting (Abrahamsson et al. 2017). As Innovative
Solutions staffs, developers are recommended to apply the application of SCRUM methodology
in presenting frequent prototypes and incremental components to the company's product
managers to ensure they are on the right path. The regularity and intensity of teamwork between
product executives and developers actually depends on their adjacent proximity and company
philosophy, whether these squads are used to such partnership. When topography is a problem,
teamwork tools such as Web and video conferencing acts as the most vital aid to the entire team.
The equivalent blending of techniques in SCRUM methodologies tends application in a
corporate situation outsourcing expansion overseas. In fact, with possible time and cultural
detaches, it is significant to build in as numerous iterative and incremental ladders and as much
ongoing interaction as is viable for the project and the company's and it’s development partner's
ethos (Vijayasarathy & Butler 2016, p98).
Whether a particular individual wants to operate with self-organized crews or a more top-down
administration approach certainly depends on the ability level and seasoning of the project
developers. Many schemes require a leader who tends to add some insistence, guidance and risk
administration to the project at the onset until team associates get accustomed to operating
together. Then the management role can be ascended back as required with subsequent growths.
The fact is that there doubtless is no perfect process for all schemes and environment, or even for
a sole one. That's why corporations need to build in everyday lessons learned conferences to
evaluate and review the process that may move more near one end of the scale or the other at
different plugs in the development cycle. In short, when selecting between SCRUM and RUP

Innovative Solutions recommends adopting the process according to the project needs, rather
than adapting the project to the progression (Ahmad et al. 2014).
