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)-

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.

Cleaning Your Home Without Any Use of Chemicals

We have gotten used to relying on a whole range of chemical products for the cleaning of our homes and offices without paying attention to how harmful such substances can be for the health or the environment.Every household actually uses stain removers and all sorts of solvents to get clean clothes, impeccable kitchens and germ-free bathrooms. However, with the development of the environmental awareness, some companies have started producing eco-friendly cleaning products. Most spot and stain removers in the eco-category are now derived from natural resources, with plant or vegetable ingredients in organic solvents.

It is false to absorb that eco-friendly cleaning products can not eliminate resistant stains and stains such as nail polish, wax, ball-point ink, glue, resins or dyes from solid or textile surfaces. If we manage to eliminate such prejudices and actually try some eco-friendly cleaning solution, we may be pleasantly surprised by the results. It is paradoxical how we soil and litter our planet while making efforts to remove the dirt from daily life. Why switch to eco-friendly cleaning? First of all your home will be clean from toxic fumes and chemicals, you will sleep better and enjoy a great sense of well-being.

There will be less health hazards for children and babies who may come in contact with toxic cleaning residues. Nor will there be any more fumes from spray bottles. Poisons should be a no-no in our lives. You can eliminate the hazardousous substances by using household pickup days, and replacing them with safer versions. Eco-friendly cleaning provides a safer environment for your children. Moreover, the fewer chemicals you use, the fewer toxic materials will be evacuated in the waste water stream. If you do not have eco-friendly cleaning products ready-made for a certain task, there are homemade solutions available too.

The Internet abounds with eco-friendly cleaning tips, you just need a bit of time, interest and patience to see how to deal with the issue. Not only the cleaning agents should be changed with eco products, but the cleaning accessories as well. Sponges, mops and rags should be all reusable and natural. A responsible human being living in the 21st century should mind the durability, health and environment impact of the products he / she purchases for home use. This kind of changes will also bring considered savings.
