  3. Front end development: It is the first visual touch-point recognized by website visitors. The phase starts with the design & transcends to QA testing. Website responsiveness & complexity of animations are the influencing cost factors in this development phase.
  4. Back end development: It comes into play when the user has interacted with the website interface via buttons and more. The main influencing factors in this phase are complex queries & data processing tasks.
  5. Testing: It is vital to test every component of the software to prevent any possible bugs. Testing helps in knowing the end capacity of the software in real business conditions that may affect its costs in long term testing.
  6. Software size: The software development costing is directly proportional to the size of the software and its user base. Its size is defined by the number of screens/pages it has and the size of the user base is defined by the number of end-users it is expected to adopt.

Why should a business get their own custom software?

  1. Competitive Edge: Customized Software provides a better competitive edge over their business competitors as the product is flexible to add or remove features whenever necessary.
  2. Business Friendly: The main advantage of customized software is that software is developed in such a way that it works according to the business.

  5. Scalable: Customized software is highly scalable fulfilling the requirements of many users within the organization.
  6. Developer Support: Whenever you are facing unexpected errors or bugs, one can easily get it solved with experienced developers who designed your solution.

What are the seven stages of the Software Development Life Cycle?
Software development life cycle stages start from :

  1. Planning: It involves project planning, manpower planning, overall cost estimations and procurement requirements.
  2. Feasibility: Check if the software solution is solving the end user problems, meeting expected requirements & resources for executing as well as delivering the project.
  3. Design & Prototyping: Design & developer team work together to figure out the software design & prototype helping in envisioning the functionality & the first ever workable version of the product.
  4. Software Development Stages: At this stage, developers need to confirm things with product owners & testers ensuring you have a working feature to share with the customers. You start seeing something resembling the final product.
  5. Software testing stage: The most crucial stage where software testers check code quality and performance ensuring smooth software development & deployment.
  6. Deployment: The output of this stage is a functional, stable software meeting the defined quality & functional parameters. In simple projects, this is like deploying the code onto a web server while in larger projects , this could involve integration with different systems.
  7. Operations & Maintenance: In this phase, developers keep a close eye on software bugs or defects. Support specialists will report issues, product owners will help prioritize them, and developers will work with testers to make improvements.
