A Comprehensive Guide to SDLC Modules

Posted by

Hey all,

Today, I will let you know a brief guide about the Modules of SDLC.

First of all, The SDLC (Software development life cycle) is a way to build software by following some specific processes.

What is SDLC (Software development life cycle)?

The SDLC is very high and potential strategy for building software. And this is the structured process that enables the production of high-quality software, at the shortest possible production time. The SDLC aims to make superior software that meets and exceeds all customer expectations and demands in a short time. The phases of the SDLC module are very energetic and profitable following the SDLC process enhances the development speed and minimizes project risks.

By following the process of SDLC the growth of production will go to the higher.

Modules of SDLC (Software development life cycle).

Here I am mentioning the high-demandable modules of SDLC lists.

Waterfall Module – The waterfall module is divided into six steps and each step is critical to know about the process of software development. The first step is the Requirement, Anyone has to make a requirement for the starting process of development because you have to understand the client’s expectations that’s why. the second step is Design, Designing is a very important step in making your product great with a good interface. the third is Development, Development is the process of coding and we can say it software engineer work process. during this process, the developer will do the coding and making the software. Forth step is Testing, The Testing step is very important to know about the status of any software because during the testing work a tester will raise bugs on the developer and they let him know the work status of the software. The fifth step is Deployment, The Deployment process gives a brief status of any software because during this process managers will do the verification & validation testing on the software, and if the software meets the client’s expectations then they will move on to the final step. The sixth step is maintenance, In the maintenance process manager will give the software to users for feedback if users give good feedback then the manager will send the product to their client.

RAD Module – In the RAD Module there are 5 steps to start the process of software development work and this is a good strategy to be followed. Let’s go with the steps the first step is Business Modeling, Business Modeling is a way to identify the model of the software according to the new modeling business era. the second is Data Modeling, Data Modeling is the insights derived from business modeling that are distilled into a collection of meaningful data entities crucial for the business. The third is Process Modeling, Process Modeling is a way to explain the collection of data into the new process that we have to follow and implement into the software. The fourth step is Application Generation, After observing all the previous steps a manager will give the records to their developers and the developers will make the project according to the modern design and to convert process and data models into prototypes.

Spiral Module – The spiral model was first defined in an article by Barry Boehm in 1986. This spiral model is based on experience with large government software projects. There are four steps to follow the spiral Module so let’s go with the steps. The First step is Planning, I think we can say it is an essential step for doing anything because without any Planning we can’t do anything and if we have a good plan for doing the work then we will do the good work. This usually involves interviewing internal and external users and preparing detailed flow diagrams showing the process or processes for which going to be developed. The second step is Risk Analysis, Risk Analysis is a solution to the projects because without taking any risk we can’t identify where we are stuck on which step. The process includes addressing the factors that may risk the successful completion of the entire project development including alternative strategies and constraints. The Third step is Engineering, Engineering is the step of the development process the software is produced along with coding and testing at the end of the phase. and according to the customer’s expectation, the developer will make code until the customer’s satisfaction. The fourth step is Evaluation, the Evaluation process is done after the completion of Development work and Testing work and in this step, the manager will give the project to their customer for verification and satisfaction. The evaluation phase allows the customer to evaluate the output of the project to date before the project continues to the next spiral.

V-Model – Due to the processing of this model we can know about the validation & verification status of every software or Product. After completing the testing work a company will focus on the V-Model step to get the results of coding and Testing. The V-model illustrates how testing activities can be integrated into each phase of the software development life cycle.

V-Model’s phases verification phases

a. Requirement Analysis – This is the first step of every software industry to gather requirements from the customer. All the managers will take the customer’s requirements from the perspective of a customer. By understanding the requirement developers can make the software and give it to the customer.

b. System Design – By doing this step every software development company will create a layout of the system/application design that is to be developed. a system designing process is the most important step in making our product into a high-level.

Here are the sub-categories of the system design process.

Architectural Design – This is a high-level process to make our project a good methodology with techniques.  Architectural design is often termed as ‘high-level design’ which is aimed at providing an overview of a solution, platform, system, product, and service.

Module Design – This work is a low-level work of deciding the module of every software design. during this work managers will select the design of any software module. The best part of this is that you may know that this module is well for the client’s expectations and today’s generation.

Data Design – This is the basic work of every software module because after completing the process of Data design you will know the structures of data at every phase and also you can do the documentation of it for your future work testing reference.

User Interface (UI) Design – As you all know, the UI is a very important thing of every software module and If a UI is well designed of the software then it will have a high chance of achieving visitors and in the future, it will be making a record of their benefits and workability.

Security Design – In today’s time many hackers are running into the environments. but why they are running? because they all are finding a chance to hack the software of any of the companies and after that, they will say their interest to the managers, and after that filling the interest of hackers they will relieve your product. Due to those kinds of reasons, Security is very important for every product or Software.

What are the advantages and Disadvantages of the V module?

There are many advantages of Vmodule and here I am mentioning the advantages of Vmodule.

Advantages –

Reduces Risk – We can call this a reduced-risk possibility process because by following the process of security design every product will be saved from Hackers. and the risk percentage of a product will be lost.

Increases Efficiency – The meaning of the risk efficiency is that, The Vmodule is passing out multiple processes and due to this the working efficiency of a product will go very high, and the capacity of this product will be increased.

Improves Quality – We can assume that after following the V module process, we have a process of Verification & validation, and during this process, a company will identify whether the Quality and capability of a product has increased or not.

Parallel Development and Testing – This process is the main component of SDLC work. During this process, a manager divides the development process into two steps: Development and Testing. By following these steps, a developer and tester will work in parallel.

Documentation – Each phase has specific deliverables, promoting thorough documentation throughout the development and testing process.

Disadvantages –

Not Ideal for Large Projects – The V module process does not work dynamically if we receive a large and complex project.

Limited flexibility – It is difficult to adapt to changing requirements or unexpected functions. This can be a problem for projects with evolving requirements or a high degree of uncertainty. If a client changes the requirement suddenly then we have to make documentation and planning for the other requirement.

Limited Client Involvement – In the V module process Limited clients are involved during the testing and Development process only giving the ideas for misunderstandings or mismatches with their expectations.

Focus on verification over validation – The V module process focuses on the verification and validation requirements because they ensure that the software meets the user’s needs or not and whether the software is built correctly or not.

Resource Intensive – The V module has a limited resources facility and after using these resources they are making good and small software with good quality because the clients are changing their requirements time by time and due to limited resources, the V module faces problems.

The 4 Phases of the Project Management Life Cycle

Hey there are 4 types of main phases of the Project Management Life Cycle work

  • Initiation
  • Planning
  • Execution
  • Closure

Initiation – During this process you have to ensure that your project is going on the Good way or not. and also do an extensive feasibility study on whether or not you should be spending your money on this project or maybe you should try something else. This initiation is most important to about your products.

Planning – After the completion of project approval you have to move on to the planning phases and you have to put the whole project development process from scratch or with some help from any previous project works.

Execution – In this process, relevant people will assist you in working on this project in the proper way. This relevant person will give you documentation for your project work and they will schedule your work time on this project.

Closure – This step is the last step of the development work and during this process, you need to close down the project development process, clear your dues, and keep your software under observation. after the validation & verification process manager will let you know the observation of the software.
