Introduction

Purpose of the study

The study purposes to explain important concept concerning the difference between the two critical methodologies to system progress that are presently applied in developing business systems: the Rational unified process (RUP) and the SCRUM development approach. Currently, there are many software procedures that an individual can select in system development. Both have strong point and weakness as the emphasis on different facades of the software development life cycle (SDLC). As a consequence, some researchers and specialists have proposed numerous hybrid approaches merging two or more software processes with the resolution of leveraging appropriate strengths thereby edifying the entire development evolution (Kniberg 2015, p14).

System development methodologies

Scrum

Scrum is an agile system development framework for managing business progressions with eminence in software development. It is anticipated for development actors from three to nine colleagues breaking their errands into various actions. The Scrum method marks a marked departure from the waterfall administration. Several shortcomings in the waterfall methodologies stimulated scrum and other supple methods. It emphasizes teamwork, functioning software, crew self-management, and the tractability in adapting to emerging business realism, thus scrum is a portion of the entire agile movement. Agile is a reaction to the failure of the governing software development project management models (including waterfall) and derives many principles from slender manufacturing (Abrahamsson, Salo, Ronkainen & Warsta 2017, p89).

Advantages

• Scrum technique projects and establishes where the project needs in the documentation phase is hard to compute.

• It is a casually controlled method that claims on recurrent apprising the progression of work through regular associations. Thus there is clear visibility of the system development.

Disadvantages

• If a mission is not well established, estimating scheme costs and time inclines to be incorrect and in such an instance, the duty can be spread over several dashes.

• The method requires dedicated team members, and if they fail to be dedicated to their duties, the project may fail.

Rational unified process (RUP)

RUP is a software development process from Rational, an IBM department that ruptures the development course into four different stages where each involves professional modeling, examination and design, implementation, testing, and application (Sharma & Wadhwa 2015, p21). The important purpose of the RUP is to provide a model for efficiently implementing commercially established approaches to expansion, for use through the intact software development life cycle. Taking essentials from other iterative software progress models, the Rational Unified Process context primarily was formed by the Rational Software Corporation that later was bought out by IBM entity in the year 2003. RUP is not an actual development model but reasonably is proposed to be adaptive and designed to the specific requests of the project, team, or entire association. It is based on a few ultimate ideas, such as the segments of development and the building chunks that define who, what, when, and how actual development will enhance (Kramer 2108, p56).

The four segments are:

1. Inception – In the inception phase, the elementary idea and edifice of the project are recognized. The crew will sit down and define if the project is substance pursuing at all, founded on the proposed project purpose, the estimated expenditures (monetary and time), and what capitals will be obligated in project completion once the go-ahead notion is provided.

2. Elaboration - The purpose of this stage is analyzing the requirements and essential system architecture. The realization of this phase is most critical, as the final landmark of this phase signifies the project transition from low-risk to high-risk, ever since the coding process takes place in the following stage.

3. Construction – This is the phase where the pattern is developed and accomplished as software is planned, transcribed, and substantiated.

4. Transition – The transition phase is when the complete product is finally unconfined and delivered to clients. It must also grip all post-release care, bug fixes, blemishes, and so forth.

Advantages

1.  RUP process delivers an adaptive competence in dealing with varying requirements through the progression lifecycle, whether they ascend from clients or from inside the scheme.

2.  Highlights the needs and appropriate enactment of accurate documentation.

Disadvantages

1. Expansively relies on skilled and expert team companions, since the mission of deeds to individual staffs requires the production of physical, pre-planned results in outcome state.

2. Given the prominence on integration over the development process, this can also be unfavorable through the testing or other junctures, where unifications are conflicting and getting in the practice of other, more significant activities (Gousios, Pinzger & Deursen 2014, p54).

Comparison of scrum and RUP processes

RUP and SCRUM development methodologies are both referred as an Agile and method project undertakings in the iterative method; hence both are software developments contexts. They are considered to be receptive, which means that the requirements and resolutions of the project advancement as a consequence of team association (Onokoy & Lavendels 2018, p34). Both also smear an iterative approach, splitting the development process into distinctive stages. Both outlines emphasize cross-functionality and corporation and promote self-management within the team. And finally, there is a prominence of product brilliance within both settings. Though RUP procedure calls for a proper description of space and significant scheme signposts are linked to exact dates, scrum research methodology smears project surfeit in its place of scope and allows the backlog to be redefined at the close by of each reiteration that takes about every four weeks. In accrual, RUP segments the project duration into four critical stages as described in the research. Even though it arouses simultaneous workflows crosswise the complete cycle, the widespread understanding is that specific actions will top during particular stages (Despa 2014, p44). On the deviating contexts, SCRUM verdicts that the entire outdated lifespan spasms into one reaffirmation. In other words, the ability for one iteration of an incantation tends recognition, and then the complete cycle occurs within one iteration.

Iterative

Timeline

Recommended for large and long-term edge level schemes with medium-to-high complexity.

Suggested for rapid enrichments and establishments that are not reliant on a bound timelines.

Category of Project/Invention

A number of Artifacts is present. Among them are; extension plan, Vision/Scope Article, Formal functional requirements package, scheme design document, among others.

Operative software is the only official artifact.

Scope

RUP scope is defined before commencement of the project and documented in the range document.

In the case of SCRUM, it applies a project backlog that is re-evaluated at each sprint completion.

Planning

Project plan is prescribed and related with multiple reviews. The idea is end-date resolute and also has middle milestones.

There is no end-to-end system plan as each succeeding iteration strategy is enhanced at the termination of the present iteration.

Sequence

The entire RUP cycle tends enhancement across four stages, but some workflows can be harmonized.

Each iteration is a complete cycle by itself.

Selection guidelines and Recommendations

Both software developments techniques have their benefits and disadvantages that go together with dynamic business development in various establishments. In having fruitful software development, several corporations have been appreciative to mutual progressions in complexity and yield the sections of each that are unrivaled suited to the specific invention and the environment (Anwar 2014, p18). As Innovative Solutions personnel, developers are endorsed to apply the SCRUM methodology in presenting current prototypes and incremental apparatuses to the company's product executives in ensuring they are performing on the right track. The uniformity and teamwork passion between product managers and developers essentially depends on their adjacent immediacy and company viewpoint, whether these teams are used to such corporation. When the structure is a problem, teamwork gears such as Web and video conferencing deeds as the most vibrant aid in communication between the team members (Hui, Yan, Quanyu & Zhiwen 2015, p274).

The corresponding blending of SCRUM techniques, methodologies tends to bid in a corporate situation outsourcing development overseas. In fact, with likely time and cultural disconnects, it is noteworthy in building numerous iterative and incremental steps and as much ongoing collaboration as is viable for the entire project. SCRUM enhances increased cost savings as constant communication guarantees the team is fully aware of all matters and changes as soon as they ascend, helping to subordinate expenses and intensification in quality (Koenig & Gregg 2014, p87). By coding and debugging features in smaller chunks, there is unremitting feedback and errors can be corrected early on, before they turn expensive in fixing. It applies an incremental tactic where a sample prototype converses with the customer. The prototype assists in understanding the key features, including the necessities. The consecutive samples reflect the changes done in the previous prototypes. This retains happening till the customer is gratified, providing improved end-product to the client. The indication is maintaining the product’s excellence in the entire development phase.

Between the two methodologies under consideration, SCRUM acts to be the better option thus as personnel in Innovative Solutions corporation I advise staffs considering the implementation of the method. RUP methodology also has benefits in business development, but SCRUM possesses several of them that primes it as a better option (Vijayasarathy & Butler 2016, p98).
