Building software for a client might be not as simple as it sounds. It does not only require developers with coding skills. The prominent IT industrials claim that this process is extensive and involves several phases.
First of all, software development is not a one-man job. When a new project requirement is there, the client looks for a team that can take up the project.
What Is the Software Development Life Cycle?
If you are talking about a blueprint to the construction of software, then, in terms of Information Technology, you want to know about the software development life cycle. SDLC is a roadmap that directs a team how they would plan, build, test, and deploy software on a platform to achieve a digital solution.
Without SDLC, it is hard to systematically build a web or mobile application that meets industry-standard quality and precision.
The SDLC phase involves several steps of communication and team creation, where the skillsets of every team member are assessed to determine the deadline of the project. There are some variables that clients and project managers take into consideration. These are project objectives, project size, team size, outages/downtime, and additional enhancements post project.
Every development team entitles itself with a software development module and follows the set of guidelines. Adhering to these protocols ensure a comprehensive, well-managed structuring of the project to realize the ultimate fulfilment of the project.
Benefits Of Software Development Life Cycle
The responsibility of deploying the project within the deadline is that of the project managers. On one hand, they need to be compliant with the specifications. On the other hand, they cannot compromise on their deliverables. To manage both these aspects together, SDLC is necessary.
Having an SDLC ensures that there is a proper working plan, dispute management between team members. They will be able to cross communicate and submit their work on time. For the budget management, the managers work tirelessly to achieve the following goals.
- Makes it easy for the team to cope up with the vastness of a large project. They can categorize the problems clearly and work towards the solution.
- Better allocation and utilization of the office resources which ensures cost-effectiveness thanks to proper management.
- The project is designed with a clear vision giving team members a boost to exercise their action plan.
- Improves cooperation and communication between participants. Direct line of communication exists in the hierarchy.
- SDLC ensures that the loss or absence of one project member will not be a reason for the project’s failure.
- Project completion takes place in several cycles. SDLC enhances the efficiency of the project, and less time is wasted on micromanaging.
It is important to note that these benefits of SDLC will be put to effect if all the employees follow work ethics. Lack of expertise and administration, and refusal of participants to follow norms will make the cycle fall apart.
Often the client just states the requirement and the project managers have to brainstorm ideas and draft the possible route to the solution of a problem. This requires the manager to discuss working models and methodologies before the start of the project.
Some of the most common SDLC models are as follows:
In this working model, the steps to figure out how the development should take place is determined first. The basic business requirement of the waterfall model is that the team needs to get prior approval from the business leads and managers before executing a change in the process.
This team management process is similar to the waterfall model. The team cannot jump into the next step unless the previous step is concluded with desired outputs. It features consistent trialling in the V-shaped model so that errors can be avoided to the maximum.
In this model, the development tasks are broken down into segments. The rational unified process of this process allows teams to dodge confinements which are present in other development cycles. Since it consists of smaller subsections, micromanaging these is simple. It makes Iterative a reliable SDLC model.
Bearing similarity to the iterative model, in the Spiral model this model highlights the smaller tasks within the project. Developers have to work efficiently on the complexities of these smaller tasks and eliminate them. Finally, the entire project is integrated.
The most followed and modern methodology for SDLC is Agile. It follows XP and Scrum methodologies and has phases of a fortnight called a sprint. After each Sprint, the developments are catered to the client. Agile is a transparent development cycle intended to produce regular, visible results.
There are more methods like the Big Bang model, which is not in vogue these days. These models complement the software development lifecycle is not just about developing the app but also includes testing, deployment, and maintenance of the app.
So, which methodology do you seem fit?
