The Basic Methodology of Software Development Services

Software development is a technically complex process which goes through various stages during the whole development procedure. The concept is termed as software (S/W) development life cycle (SDLC) and involves various stages of (S/W) development. To successfully offer software development services, organizations should define a development methodology that suits the requirements of the project. Different projects may require different methodologies therefore software development service providers must evaluate the project requirements first and then formulate the strategy for the software development life cycle.

Most of the software development service providers have a pre-defined methodology that is implemented while developing a software. The process gets a little modified according to the project requirements but the essence of the project development procedure remains the same. The basic stages of software development are as mentioned below:

Requirements Specifications: The first and foremost step while developing software must be gathering the requirements of the project. The organizations must start with analyzing the feasibility and the requirements of the project. Some questions that must be clarified in this phase are:

What are client’s expectations of the project?

What would the user want in the software?

Is the project technically feasible or not?

The above questions, along with many more, must be answered and properly justified before software development service providers move any further.

Design: This stage involves development of an outlay for developing the project with all the little details included. The project requirements are evaluated and an implementation strategy for achieving these requirements in the form of a software is formulated. The designing phase is divided into two categories i.e. system design and component design. The system design is design of the software as a whole where questions like how the individual components will interact with each other are answered. The component design phase, as the name suggests, deals with the planning for each individual component.

Implementation: The components are actually created in the implementation phase. The design layout created in the previous phase is implemented and converted into a machine language that the computer can understand and respond to. Programming languages such as C, C++, C#, Asp.Net, PHP etc are used according to the project requirement to achieve the best possible results. The source code and database are created in the implementation phase. Accurate and effective designing of the software is essential for a successful implementation of the software.

Testing: The testing phase usually starts after the components are created but in some cases the software development service provider can start the testing along with the implementation phase. This methodology may require a little more effort and time but the end solution is void of any discrepancies or errors as they are detected and removed as soon as a component is developed.

Installation: The components of the software are combined together and the completed software is installed and executed on a computer system. If all the previous phases have been performed expertly then there will be no problem in the installation phase. A thorough testing is again recommended after installing the software to make sure that the end solution is working as desired.

Maintenance: It has been noticed that almost every software goes through changes and modification after it is completed. This may be due to some new requirements, overlooked features or the change in the business strategy. This requires constant evaluation and maintenance of the software.

Most of the software (S/W) development service providers follow the above described development methodology for creating softwares. It is the basic methodology of S/W development services. Once the software is completed and delivered successfully, the task of the service provider does not end. A professional S/W development company will offer maintenance services to insure a smooth and well functioning solution to their clients.

What Is a Software Development Life Cycle?

A set of instructions for the computer to read and understand to perform a specific task is called a Software. Software development is the process to use computer programming to develop a software. This is not new for many, but the topic under consideration will be new for many. SDLC or Software Development Life Cycle, is the process of developing a new software.

The process of developing a software is not difficult to understand. The procedure of SDLC goes like this:

  1. Gathering and then analyzing the requirements to develop a software
  2. Designing of the software
  3. Coding or programming
  4. Testing the software
  5. Deployment
  6. Maintaining the software

Gathering and Then Analyzing the Requirements to Develop a Software

This is the initial phase. Like starting any business, starting to work on a new software requires a plan. The planning phase will include the project managers, stakeholders and even some senior software developers. No matter how professional or for how long the software development company has been operating, the planning is not an easy phase to follow. Although, it would take less time for experts to plan a new project and then to start working on it but still there will be some questions that must always be answered before taking on any project. Following are some questions, which needs answers before taking on the project:

  • Who will be using the software?
  • How they will be using it?
  • What is the required data to input?
  • What will be the output of the input data?
  • What is the purpose?
  • What skills are required?Will there be a need to hire new personnel or the current staff have the right skills and the capacity to work on this new project?

Find their answers. Is the project worth it? A thorough analysis is required here. There will be more questions that need to be answered before taking on this new project. All the work is documented for future reference.

Designing of the Software

Now comes the second phase, the designing of the software. On the basis of the documentation and the results of the first phase, the system and the software is given a design. From this, the developers comes to know the requirements of the hardware and system required to complete their new project. This phase will also define the system architecture. The designing phase will set the requirements for the next phase.

Coding or Programming

Here comes the role of the software developers. The system design documents are now divided into modules and the developers now start their job. This is going to be the longest phase of all. Programming is done here and it’s known to all that programming isn’t an easy job. It needs plenty of time, expertise and patience. Once done, the software developer sends their work to the tester.

Testing the Software

When in the production business, the quality of the product is always monitored and tested. So is the case with a software development. When the coding is done, the software developer sends their work to the Software Quality Assurance department /personnel. They will overlook the work of the software developers. The software quality assurance or the SQA for short will look for bugs and test the software. The test will be made as per the requirements and the guidelines mentioned in the requirements document. Unit testing, integration testing, system testing, acceptance testing is done by the SQA and if found deviations or errors, it’s sent back to the software developer. The procedures will keeps on repeating themselves until the software is bugs free and ready to deploy.

Deployment of the Software

On successful completion of the software and the testing, it is sent to the concerned client or is available to the public.

Maintaining the Software

Only the non-serious professionals or the ones not willing to carry on their business will not look back to their software but the serious developers will. Every software needs updating and maintenance. Whenever the software encounters some troubles, the software developing company will be there to fix it.

SDLC follows a simple procedure and it doesn’t require you to be a businessperson to know all the phases of SDLC. Every software developer and software developing company knows it all. So when hiring a software developing company you can rest assure that the procedure will be done in a professional way and the best product will be delivered.

Job Roles Defined: Tasks That a Software Development Company Generally Carries Out

Introduction

Companies who handle the task of manufacturing the software service follow a process consisting of certain strategies step by step in order to deliver optimized software on the basis of the client’s requirements.

But prior to that, comes the procedure of developing software. Tailoring a software from the scratch or modifying existing software for the further modification compels the developers to go through a monotonous, painful and frustrating method. But most of them don’t know that there are thousands of ways through which the software development process can be facilitated.

SDLC or Systems Development Life Cycle

A software is always created for future use. Most of the organizations produce it for their own usage and some of them are produced for the clients. Sometimes, the organizations make the software from scratch and sometimes, they modify the existing software. Due to this reason, most of the big software development companies adopt SDLC or Systems Development Life Cycle method also known as the Software Development Life Cycle that actually splits the entire process into separate phases that includes computer programming, planning, developing, documenting, testing, bug fixing and finally deploying & maintaining frameworks and applications that consequence in a software production.

Drawbacks

Splitting of this entire process may facilitate the procedure, but it also produces certain risks that may come up at the time of estimation, scheduling, and testing. To avoid this thing, most of the organizations maintain a set of rules or proven guidelines for a successful project handling as per the customer requirements.

What strategies do the organizations use nowadays?

The SDLC models that the big organizations or MNCs follow can be of various types. Nowadays, the Agile software development methodology is in use the most because of its easy-to-use technologies and cooperative strategies.

The entire process can be divided into two portions. First is the Software Creation and second is the Software Project Management. A proper project delivery depends on the proper execution of the multiple operations to accomplish the targeted result within the deadline. But creating the software is not enough. Testing and maintaining of the software for the lifetime takes a lot of efforts of the developers.

Purpose of software creation service maintenance

There is a vast difference between creating website or application and producing software. To be very frank, developing software itself is an entire process and most of its parts are elusive. This is because the technologies are highly volatile and are constantly changing. That is why most of the software are custom made and are made on the basis of the requirements. The frequently changing nature and the advancement of the technologies are quite vulnerable to the business & environmental challenges that produce risks for which it is important to maintain the software production service.

The necessity of a software project manager

For the proper maintenance, most software development companies deploy software project manager. The challenges that the software project manager generally handles are as below-

Maintaining the quality of the software.
Delivering the quality software within the deadline.
Following the process and SDLC methodologies while developing the software.
Keeping the cost within the client’s estimated budget.
