Software Development Life Cycle – Introduction Model Stages and Advantages

What is the Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is essentially the process or phases of a model or methodology, which software engineers and developers follow in developing an application or software. In simpler words, it is a process consisting of a series of planned activities for planning, creating, testing, deploying and maintenance of software.

SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

What are the major SDLC Models, followed in the IT Industry?

There are various SDLS models, which are currently followed in the IT Industry. Often referred as ‘Software Development Process Models’, all the process models follow unique software development steps, ensuring 100% success of the development projects.

The major software development life cycle models are-

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

Other related models are Rapid Application Development (RAD), Prototype and Agile Models.

The advantages of choosing an appropriate Software Development Life Cycle (SDLC)-

  • Increased Product Quality
  • Increased Development Speed
  • Improved Client Relations
  • Improved Tracking & Control
  • Decreased Project Risks
  • Decreased Project Management Overhead

What are the different stages of SDLC?

Stage 1:

Planning and Requirement Analysis

This is the most important stage in the SDLC. This stage needs input from the customers, sales team, industry experts, a marketing team and their survey reports. After which, senior business managers and developers of a software development company plan the project approach and the development model.

Stage 2:

Designing

After the analysis of requirements and finalizing the Design Document Specification (DDS), the product architecture is designed by an expert team. This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

At this stage, the final product is deployed at the client base. At times, the software is integrated with the client’s current application and database. All the deployment and integration works are done under the guidance of expert software engineers and developers.

Stage 6:

Maintenance & Support

Most of the reputed IT development companies also provide complete maintenance and technical support, post deployment of the final product at client base.

Ways To Effectively Convey The Business’ Needs To The Software Developer

The Need For Effective Communication

Many experts believe that the first step in the software development process is properly conveying the needs and requirements of the business to the software developer. This belief cannot be any truer as the need to effective communication between the business and the software developer is extremely integral to the overall success of the development project. There are countless stories where clients and software application users grumble about novice and unskilled developers who delivered a product completely at odds with what they were paid to develop.

Ways To Ensure Proper Communication

Looking at all these trends, it barely needs to be emphasized how crucial it is for businesses to communicate what they want. Effective communication can help businesses to develop and deliver the software within the prescribed deadline and budget. The following steps can help businesses to ensure the best possible outcome:

Define the business need -It is obvious how integral it is for a business to properly define its needs and requirements before the project is initiated. However, businesses need to keep in mind that It is equally important that the software developers are conveyed what the requirements of the business are. If the business does not make an effort in conveying details on requirements in an articulate and eloquent manner, the final product of the project is bound to come out different and the software developers cannot be blamed for it.

Describe the problem rather than the solution -Once the goals and objectives of the project have been successfully established by the software development company, it needs to devise a strategy that defines how these goals should be approached by its team of developers. It is best to help software developers identify what problems need to be fixed. It is also important for the betterment of the project to value the input of the developers and to trust them on their recommendations as this helps to boost their confidence.

Define the users -Businesses should also define the audience to whom they plan to make the software available. This is essential when the software has to meet certain personalization criteria which require it to be tailored according to the specific tastes of the client. Defining what market niche the software is targeted to will help the software developer to better understand its requirements and dynamics.

Distinguish between user interface, platform, and content -Businesses are naturally possessive and personal about their software projects.However, developers may not necessarily employ the same perspective when they look at things. There is a high chance that developers will see some important differences that differentiate their roles. These differences are the user interface, platform, data managed and the actual data. The business should make sure that the software developer is able to distinguish between these three aspects during the development phase.

Conclusion
This discussion simply explains tips that are essential in order to convey to the developers what the requirements of the business are. It does not detail how a right developer is to be chosen or how to ensure successful completion of the software development project. However, it is enough to help businesses clearly define software requirements, which is the first step towards successful completion of the project.

Custom Software Development For Everyday People

For those who are not technologically advanced, “custom software development” is software that is developed for a particular organization or it can be a type of software that is different from other types of software that are already available to the public. So, what’s the big deal about customized software?

In this growing age of technology, custom software development and software application development are appealing to a growing number of businesses and leaders. As the name implies, if it’s customized, it typically helps you perform a function better, and in the business world, this can mean having that extra competitive edge over your competition. For a real-life scenario, think about the following example: My boyfriend is six feet, four inches tall and always claims that the “world is not made for tall people”. His idea of something great would be customized countertops in the kitchen that are strategically placed taller in order to accommodate his height so that he doesn’t have to stoop over as much. In other words, it would make it significantly easier on him, thereby increasing his work productivity when putting together a meal.

In a similar vein, many businesses and various other corporations prefer to have custom software development and/or software application development because it would not only save them time, it would also save them valuable resources and money. In the business world, time is money and everything seems to boil down to finding the most cost-effective, high quality method for operating in order to perform and deliver quality results in a short amount of time. It is for this reason that the emergence of customized software development has really taken off.

Software application development and custom software development first begin by having a software developer or a group of software developers study your company or business in order to figure out what the business requirements are. This will involve much planning and development at each stage of the process. For this reason, the relationship that your company has with the software developer(s) is extremely important. Make sure that you communicate effectively and often with your software development team, this way you will both have a clear understanding of the direction and number of required hours that will be needed to devote to the project.

As customized software continues to take off in the business world, it is the hope of many that employees will have a better understanding and grasp of how to utilize software innovations in order to more effectively and seamlessly operate and promote their business brands. Additionally, as more businesses begin to take advantage of these software services, it will no doubt generate more competition among software developers to do an even more upstanding job with figuring out what sorts of technological advances are out there to benefit the company that they are working for. The result of the increase in customized software will, no doubt, generate competition among software developers in terms of ensuring that various organizations get the most bang for their buck.
