The deployment of any nascent information system often requires meticulously scheduled strategy. It involves the planning, creation, testing and deployment of all relevant concepts that system engineers require in order for them to come up with a fully-functional structure that will benefit consumers. Pursuant to this quest, the systems development life cycle (SDLC) utilizes a wide array of software and hardware configurations to ensure that these creations are free of any blight. In essence, it acts as a spellcheck for those in the software development arena and renowned for flagging any errors that may be present at any given stage. The aim here is to identify the errors as soon as possible before the team decides to continue with successive stages (Langer, 2012, p. 90).

Moreover, the systems development life cycles (SDLC) has been hailed by innovation pundits as a novel technology since it lays out concise plans that, more often than not, get everything right the first time. Consequently, journal article seeks to analyze three distinct systems development life cycles (SDLC) methodologies, together with their pros and cons in addition to an analysis of two companies that currently using various innovative SDLC methodologies. Furthermore, as an addendum, this article will also contain a systems development life cycles (SDLC) plan supporting acquisition, connection and sustainment of a new Database Management System.
Systems Development Life Cycles (SDLC) Methodologies
Agile Development Methodology
As a software
development ideology, Agile is highly valued for its ability to articulate
well-organized procedures for project management. This therefore means that
recurrent alterations can be made at any given point during the development of
taxing of software engineering projects. Lately, Agile has become a chief
player in software development initiatives and also a major driving force in
various types of tech and non-tech initiatives. One of the foremost advantages
of using this system is the aforementioned allowance of small incremental
changes that usually set the model apart from previous releases (Langer, 2012, p. 90).
Teams, therefore, have an easier time identifying minuscule issues that may be
present in the projects before having them snowball into significant problems.
Additionally, it minimizes the likelihood of mistakes in the development stage
by building software in iterations (short time boxes) that are thoroughly
scrutinized. Nonetheless, there is usually a lack of documentation efficiency
since the model solely focuses on working with the software alone.
The Waterfall model is an integral part the software engineering world. This is because it seeks to clarify all processes that will take place into a linear flow with itemized sequences. Users therefore get a unique opportunity to comprehend levels created progressively. It is considered the oldest of all known a systems development life cycles (SDLC) methodologies and a forthright approach also one that explains what each stage entails. Each leg is dependent upon data gathered from the previous stage which occurs before it ultimately takes on a life of its own (Langer, 2013).

One of the advantages of the waterfall model was that it was easy to understand when presented to any layman and was also quite functional in terms of its dexterity. It simplicity therefore makes it easy to use; saving personnel a significant amount of their valuable time that could be better used completing other tasks. However, the downside of this methodology is its rigidity. Any delay, as a result of this shortcoming may throw the entire project off kilter and hinder progress. In addition to this, it only matches precise needs by users and therefore not recommended for long-term projects.
Lean Development Methodology
The development of this particular model was enthused by lean manufacturing principles that are currently in vogue in the business community. The principles found herein aimed to eliminate waste, intensify learning, make deliveries within the shortest time possible and build integrity. This ideology essentially focused on being present in the moment and working only on one task, as opposed to multi-tasking. It therefore comes as no surprise that the Lean model works efficiently in large firms where project teams are often tasked with pinpointing opportunities that will go a long way in cutting waste and reducing documentation (Roebuck, 2012). In this model, developers lay the utmost emphasis on the formation of manageable software whose full potential can be harnessed effectively. The main purpose of this methodology is to improve the quality of the software created even when teams have to grapple with a restricted budget and in one-third of the expected delivery time (Roebuck, 2011, p. 78). An immediate advantage of using this model is that it can be utilized even with a low budget and with debacles such as time restrictions. By so doing, it allows for the early delivery of products that are then released to consumers. Conversely, a typical disadvantage of this model is its conceivability. A team’s workability is often a deciding factor with regard to success during the various development process phases.
Companies using Innovative SDLC Methodologies
UM Technologies and its application of the Rapid Application Development (RAD)
In the landscape of
software development, UM Technologies stands out as a trailblazer in as far as
using the rapid application development (RAD) model is concerned. This
U.S-based technology firm has managed to minimize its software development time
while thriving at maximizing its progress. At the core of its success is the
rapid application model (RAD) which basically functions by minimizing software structuring
while intensifying prototyping. Software developers are therefore uniquely
placed to shift with the requirements of a fast-paced market that is constantly
undergoing massive changes. By using this model, project teams at UM
Technologies are able to adapt easily and are more flexible as development
progresses. Also, the teams can monitor progress accurately while gathering
useful feedback from the customers.
FineSoft Technologies and its use of Dynamic Systems Development Method (DSDM)
In carrying out its day to day
activities, FineSoft Technologies is notably making use of the dynamic systems
development method (DSDM) in its software development endeavors. This
incremental approach first begins my carrying out a feasibility and business
study that is meant to aid the firm in having a better understanding of market
dynamics. It is only after this phase that the functional model can be
thoroughly assessed and decisions made for the purpose of prototype iteration.
This particular method has therefore allowed FineSoft Technologies to evolve in
the field of project development by allowing various users to collaborate
during different software creation phases. These teams are therefore more
empowered simply because they are self-managed and can make important
project-level decisions when required. The visibility and sheer transparency
that is thus created enables all team players to communicate regularly and
relay critical information to upper management.

information with regard to the project will be discussed during this phase and
assessed for feasibility. The purpose of carrying out this initial discussion
is to make certain that groundwork is laid for analysis and research. Requirements
are therefore appraised to ensure that all players have a firm comprehension of
user business needs and project scope.
This stage often
involves the project manager as the chief player tasked with deciding whether
or not they should give the green light for its commencement. It is therefore
paramount that the project manager understands all aspects of their project,
its latitude and even approach. An estimate of the time that will probably be
spent on the project is also made here to make sure that it meets company
Start of Development
After laying the
groundwork, analysis and evaluation the project is now set to begin after
formal approval. Any work that will be carried out by the developers will be
based on their earlier developed scoping plan and any other requirements that
may have been suggested by clients. Additionally, the project team also reviews
the push code in case incremental reviews are required while developing the
team has to make certain that the project timeline is observed and delivery
done on time. The project manager is therefore tasked with ensuring that
periodic status updates are provided to all relevant stakeholders to build
confidence in the team’s ability to deliver. The introduction and phasing out
of resources is also done here while conducting an appropriate quality
throughout the time allotted is presented for review to make sure that all
requirements were followed to the letter. The code is thus pushed for review
prior to its final deployment as a way of curtailing the inclusion of any
errors into the final product. The software is assessed for any defects or bugs
which ensures its fidelity once it is released to consumers.
Fundamentally, this is where the final product goes live. All parameters are observed and the software now becomes ready for use. Nevertheless, the team responsible for creating it is tasked with thoroughly assessing it for any impairment that may have been overlooked. The software is then deployed to consumers and is now ready for use.
