When it comes to creating software for an enterprise or some complicated  [CRM software](https://flatlogic.com/solutions), it can be difficult to know how to start. After all, there are many factors to consider, such as defining the problem correctly and ensuring that the software can effectively address it.

Creating software without planning is a recipe for disaster. Without proper planning, the software may be rushed, inefficient, and lacking the features needed. Furthermore, the software may be challenging to maintain and upgrade, as it was not designed with scalability or extensibility.

## Creating software “as-is” vs. planning

Planning is an essential part of creating any software, as it allows the developers to understand the scope of the project, identify the best technologies to use, and create a timeline to ensure the project is completed on time. Just as with everything in life, having a plan is better than not having one.

One of many approaches that can be helpful in navigating this process is the  **Software Development Life Cycle**  (SDLC). This [framework](https://flatlogic.com/blog/top-10-javascript-frameworks-to-use-in-2022/)  provides a structured approach to  [software development](https://flatlogic.com/blog/19-essential-web-development-tools-for-the-modern-software-development-process/), guiding the process from conception to deployment. So how would you know where to begin with it?

Then how would you ensure that you define the problem correctly so that your software can handle it correctly? Perhaps, on the other hand, what if you already get the software’s code base but don’t know what to do with it? These questions are the most powerful reason for the implementation of something like  [SDLC](https://flatlogic.com/blog/how-to-write-the-software-development-project-brief/).

## What is SDLC?

SDLC is a  [framework](https://flatlogic.com/blog/8-reasons-to-use-javascript-libraries-in-project-management-apps/)  that outlines the steps necessary to create an effective and efficient  [software system](https://flatlogic.com/blog/10-best-react-codebase-generators/). SDLC solutions can help organizations address various problems, including

-   Poorly planned projects that end up taking longer than expected or going over budget.
-   Unorganized development processes lead to delays and unnecessary mistakes.
-   Unclear communication between teams or departments results in misunderstandings and mistakes.
-   Lack of visibility into project progress, leading to unplanned delays.
-   Insufficient testing and quality assurance processes lead to poor quality outcomes.

## SDLC Models

The SDLC Models are a set of methods used to create software applications. There are several different types of models, including the Waterfall Model, the Agile Model, the DevOps Model, the Spiral Model, the Prototype Model, and the Iterative Model.

-   The Waterfall Model is a traditional method that follows a linear approach, with each phase of the SDLC being completed in sequential order.
-   The Agile Model is a more modern approach that focuses on rapid development, short sprints, and frequent feedback.
-   The DevOps Model is a hybrid of the Waterfall and Agile models that combines the best of both approaches.
-   The Spiral Model is a risk-focused approach that allows for rapid iteration.
-   The Prototype Model is an iterative approach that focuses on creating a prototype and testing it before proceeding with the development.
-   Finally, the Iterative Model is an incremental approach that focuses on making small, incremental changes to the software.

Each model has its benefits and drawbacks, and it is important to choose the right model for the project. It is important to ensure that the project team is familiar with the selected model before beginning the project. This phase is important to ensure that the software is properly developed and the project is completed on time and within budget. The team should also consider the scalability of the model to ensure that the software can grow and evolve as needed. Furthermore, the team should create process documentation to ensure that the process is properly documented and can be followed by all members of the team. This documentation should include the steps of the model, the tools and techniques used, and any best practices that the team should follow. This documentation should be updated regularly to ensure that the process remains up-to-date and that the team is aware of any changes or updates.
