All software development processes must follow a professional standard in which the standard procedures are used. Some of the major software development processes used include Waterfall Model, Agile Software Development model, Rapid Development Model, and also Prototyping. Each of these SDLC models follow particular conventional standards set by the different organizations (Rossberg, 2014). The purpose of system development life cycle is to ensure that business requirements are. The process of coming up with a system from scratch to the point where it is to be implemented into the business environment or sold out into the market is the software development life cycle, which is series of processes depending on the model chosen by the developer or the system analyst conducting the system development. Software development life cycle regards the professional process of coming up with a system for use within a business environment.
7-Step SDLC Model: Traditional SDLC Model
This is the most basic model majorly used in the market by most system analysts, and it follows a series of seven different systematic steps to be fully completed. The steps range from system planning, system analysis, system design, system development, system testing, system implementation, and system maintenance. These steps are sequential and perform a similar role of driving towards achieving the sole purpose of final system functionality. According to this 7-step model, the first phase of system planning involves identification of the project requirements. These project scopes are then analyzed and proper required operational standards are identified for correct solutions. Part of the analyses conducted include parameters such as cost implications on the business organization, time required to complete the system, as well as hardware and software requirements that will be used. All processes must be followed lest any skip of any of these processes would impact heavily on the given organization or client in this case, since a miscalculation of any form would cost the company or the analyst. In each step, specific activities are carried out to ensure that the final product achieves its functionality as per the client’s requests.
The next phase of software development life cycle is the feasibility study. Ritchie (2012) proposes that the analysis phase requires proper information gathering techniques and definition of constraints that will be used in the system. The phase involves different techniques of acquiring sufficient information before proceeding to building the system, and this information would be in form of data such as the organization’s processing requirements. The information can be gathered using techniques such as interviews or questionnaires, with subjectivity to have maximum information.
After sufficiently acquiring relevant information, the system analyst the ...
The document provides an overview of the Software Development Life Cycle (SDLC), which is a process used to develop software in a logical, structured manner. It consists of six phases - system planning, system analysis, system design, system coding, system testing, and deployment and maintenance. The goal of the SDLC is to produce high-quality software that meets customer expectations with the highest quality, lowest cost, and shortest time. Each phase results in deliverables for the next phase and aims to gradually develop the system from inception of an idea through implementation and delivery.
Overview Of System Development Life Cycle (SDLC)Nicole Savoie
The document discusses the system development life cycle (SDLC), which is a process used for developing systems from planning through implementation. It contains four main steps: analysis, planning, design, and implementation. During analysis, data flow diagrams are used to model the system's processes. Consistency between context and lower-level data flow diagrams is important for an easy-to-follow process model. SDLC is also used to determine how an information system can support business needs by designing, building, and delivering the system to users through the analysis, design, implementation, and testing phases. Procedure models created during analysis help define requirements graphically. Reliability of the process model is key to improving later SDLC stages.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

6. Systems-
Development
LifeCycle
The first development methodology we are going to review is the systems-
development life cycle (SDLC).This methodology was first developed in the
1960s to manage the large software projects associated with corporate systems
running on mainframes. It is a very structured and risk-averse methodology
designed to manage large projects that included multiple programmers and
systems that would have a large impact on the organization.
Various definitions of the SDLC methodology exist, but most contain the
following phases.
1) Preliminary Analysis. In this phase, a review is done of the
request. Is creating a solution possible?What alternatives exist?
What is currently being done about it? Is this project a good fit for
our organization?A key part of this step is a feasibility analysis,
which includes an analysis of the technical feasibility (is it possible
to create this?), the economic feasibility (can we afford to do this?),
and the legal feasibility (are we allowed to do this?).This step is
important in determining if the project should even get started.
7. Systems-
Development
LifeCycle
2) SystemAnalysis. In this phase, one or more system analysts work
with different stakeholder groups to determine the specific
requirements for the new system. No programming is done in this step.
Instead, procedures are documented, key players are interviewed, and
data requirements are developed in order to get an overall picture of
exactly what the system is supposed to do.The result of this phase is a
system-requirements document.
3) System Design. In this phase, a designer takes the system-
requirements document created in the previous phase and develops the
specific technical details required for the system. It is in this phase that
the business requirements are translated into specific technical
requirements.The design for the user interface, database, data inputs
and outputs, and reporting are developed here.The result of this phase is
a system-design document.This document will have everything a
programmer will need to actually create the system.
8. Systems-
Development
LifeCycle
4) Programming. The code finally gets written in the programming
phase. Using the system-design document as a guide, a programmer (or
team of programmers) develop the program.The result of this phase is
an initial working program that meets the requirements laid out in the
system-analysis phase and the design developed in the system-design
phase.
5)Testing. In the testing phase, the software program developed in the
previous phase is put through a series of structured tests.The first is a
unit test, which tests individual parts of the code for errors or bugs. Next
is a system test, where the different components of the system are
tested to ensure that they work together properly. Finally, the user-
acceptance test allows those that will be using the software to test the
system to ensure that it meets their standards.Any bugs, errors, or
problems found during testing are addressed and then tested again.
9. Systems-
Development
LifeCycle
6) Implementation. Once the new system is developed and tested, it
has to be implemented in the organization.This phase includes training
the users, providing documentation, and conversion from any previous
system to the new system. Implementation can take many forms,
depending on the type of system, the number and type of users, and
how urgent it is that the system become operational.These different
forms of implementation are covered later in the chapter.
7) Maintenance. This final phase takes place once the implementation
phase is complete. In this phase, the system has a structured support
process in place: reported bugs are fixed and requests for new features
are evaluated and implemented; system updates and backups are
performed on a regular basis.
10. Models of the
System
Development
LifeCycle
The system development life cycle, known as the SDLC, is the
industry-standard approach to managing phases of an
engineering project.
Think of it as the equivalent to the scientific method for software
development and other IT initiatives.
The common breakdown of the SDLC includes seven phases that
trace a product or project from a planned idea to its final release
into operation and maintenance.
There is flexibility within the SDLC. In recent decades a number of
different models and methods have gained popularity.
11. 1.Waterfall
The waterfall approach is one of the oldest SDLC models, but it has
fallen out of favor in recent years.This model involves a rigid structure
that demands all system requirements be defined at the very start of a
project. Only then can the design and development stages begin.
Once development is complete, the product is tested against the initial
requirements and rework is assigned.Companies in the software
industry typically need more flexibility that what the waterfall
methodology offers, but it still remains a strong solution for certain
types of projects especially government contractors.
12. 2. Iterative The iterative methodology takes the waterfall model and cycles
through it several times in small increments. Rather than
stretching the entire project across the phases of the SDLC, each
step is turned into several mini-projects that can add value as the
product evolves.
The iterative approach shares many of the same goals as the agile
model, except external customers are less involved and the scope
of each increment is normally fixed.
13. 3. DevOps
DevOps is one of the newest SDLC methodologies and is being adopted
by many software companies and IT organizations.As its name suggests,
the premise of DevOps is to bring development teams together with
operational teams in order to streamline delivery and support.
The advantages of such an approach are that changes become more
fluid, while organizational risk is reduced.Teams must have flexible
resources in order for a DevOps arrangement to succeed.
14. 4.V-Model
An evolution of the classic waterfall methodology, the v-model SDLC
process steps are flipped upwards after the coding phase.The v-model
has a very strict approach, with the next phase beginning only when the
previous phase is complete.
This lack of flexibility and higher-risk method isn’t recommended for
small projects, but the v-model is easier to manage and control. For
projects where requirements are static and clearly stated, and where
early testing is desired, this approach can be a good choice.
15. 5.Spiral
The spiral methodology allows teams to adopt multiple SDLC
models based on the risk patterns of the given project. A blend of
the iterative and waterfall approaches, the challenge with the spiral
model is knowing when is the right moment to move onto the next
phase.
Business that aren’t sure about their requirements or expect major
edits during their mid to high-risk project can benefit from the
scalability of this methodology.
16. 6.Agile
The agile methodology is the opposite of the waterfall approach. Rather
than treating requirements, design, and testing as large sequential
steps, an agile model makes them all ongoing processes that require
involvement from developers, management, and customers.
Work is typically broken into 2-4 week segments known as “sprints,” in
which the responsible teams tackle the major needs of their customers
and perform testing as they go. Agile tends to work well in small
organizations, especially startups, where speed and flexibility is
essential.
The characteristics of agile methods include:
small cross-functional teams that include development-team members
and users;
daily status meetings to discuss the current state of the project;
short time-frame increments (from days to one or two weeks) for each
change to be completed; and
at the end of each iteration, a working project is completed to demonstrate
to the stakeholders.
The goal of the agile methodologies is to provide the flexibility of an
iterative approach while ensuring a quality product.
17. 7. Lean
The agile and lean approaches are closely interconnected, as they both
focus on delivery speed and continuous improvement. In contrast, the
lean model is rooted in manufacturing best practices where excess
waste and effort are seen as the largest risk to an organization.
When it comes to software and projects, the lean SDLC methodology
focuses on reducing waste in every phase, including scheduling, cost,
and scope.This approach is most compelling for organizations with
strict hardware requirements and other procurement needs.
18. 8. Rapid
Application
Development
Rapid application development (RAD) is a software-development (or
systems-development) methodology that focuses on quickly building a
working model of the software, getting feedback from users, and then using
that feedback to update the working model.After several iterations of
development, a final version is developed and implemented.
RAD methodology is much more compressed than SDLC. Many of the SDLC
steps are combined and the focus is on user participation and iteration.This
methodology is much better suited for smaller projects than SDLC and has
the added advantage of giving users the ability to provide feedback
throughout the process. SDLC requires more documentation and attention
to detail and is well suited to large, resource-intensive projects. RAD makes
more sense for smaller projects that are less resource-intensive and need to
be developed quickly.
19. 9. Prototype
Model
A prototype is an early approximation of the final system or
product.This mode is useful for systems where requirements are
not known in detail during development.
In this model, customers can realize the system requirement after
the prototype is brought into operation. It allows more accurate,
flexible design and development. It takes a low cost in design and
development time.
