Let Waterfall Model be extinct

The waterfall is not dead

I cannot believe that in 2019 a lot of companies are still using the waterfall model. Although I knew that some rare cases of projects need a waterfall model, the cases I have noticed were not one of them. Those companies did not change their traditional implementation methodology to deliver a quicker value to their customers.

Therefore, This article will discuss two important models that can help those who are still using the waterfall to deliver a quicker value to the customers without the need to be an agile company. But, it is the first step toward the change to agile.

The best SDLC model

I received a lot of emails and comments regarding the best software development life cycle model. So, I had to write my opinion about that.

Actually, I think there is nothing called the best in absolute general, the best for me maybe not the best for you at this moment. Similarly, there is nothing called the best SDLC model in absolute general, you need to decide which one you need to use according to the software project context and what product or software you are developing, what about your competitors? And what are the team capabilities you have?

Choosing the right Software development life cycle model

March 21, 2012December 16, 2020Mohamed Sami

Selecting a Software Development Life Cycle (SDLC) methodology is a challenging task for many organizations and software engineers. What tends to make it challenging is the fact that few organizations know what are the criteria to use in selecting a methodology to add value to the organization. Fewer still understand that a methodology might apply to more than one Life Cycle Model. Before considering a framework for selecting a given SDLC methodology, we need to define the different types and illustrate the advantages and disadvantages of those models (please see the Software Development Life Cycle Models and Methodologies).

Software Development Life Cycle Models and Methodologies

Introduction

Software development life cycle (SDLC) is a series of phases that provide a common understanding of the software building process. How the software will be realized and developed from the business understanding and requirements elicitation phase to convert these business ideas and requirements into functions and features until its usage and operation to achieve the business needs. A good software engineer should have enough knowledge on how to choose the SDLC model based on the project context and the business requirements.

Therefore, it may be required to choose the right SDLC model according to the specific concerns and requirements of the project to ensure its success. I wrote another article on how to choose the right SDLC, you can follow this link for more information. Moreover, to learn more about Software Testing life cycles and SDLC phases you follow the links highlighted here.

In this article, we will explore the different types of SDLC models and the advantages and disadvantages of each one, and when to use them.
