Migrate your traditional build software development to the new technology platform and get better insights.

Software development is the whole end to end process. Mostly its to transform current manual human work into the newer way of automated processing. The software can be created which can make any computing task easy. Through Software development, we can eradicate major human errors and make the process smooth, fast and accurate. Majorly the need to make a software comes out of 2 situations 1) Task becomes tedious and takes a lot of human efforts. 2) Migrating old software.


Software Development Life Cycle

The software development life cycle (SDLC) is 7 stages.

  • Planning
  • Requirements gathering
  • Design
  • Development
  • Testing
  • Deployment, and
  • Maintenance

Each stage holds significance in delivering and deployment of successful software.

Custom Software Development Process

Sigma Data Systems follows each stage precisely to deliver world-class error-free software. They have qualified UI/UX designers and developers in various technologies. They work in Python, JAVA, PHP, React.js, Node.js, Angular.js, Golang, etc. Due to its mixed pool of technology developers, they can create a hybrid architecture to support the best of each technology. 

It has experienced QA to maintain the quality of the software throughout the development cycle. It engages the QA professional to keep a tap on quality and also continue with regression testing. Sigma Data Systems also has a separate DevOps team to make the deployment process continuous and smooth.


Methods of managing custom software development projects

There are various software development methodologies to drive the project. These are guiding principles that can drive the project on the correct roadmap. It keeps all the involved stakeholders together moving on the same goal. However, every methodology has its unique characteristics. Major methodologies to choose from are described below:

  • Waterfall 
  • Agile
  • Hybrid

The choice of methodology depends on the type and size of the project. Each has its own pros and cons. Sigma Data Systems can consult on making the choice of the methodologies. Sigma Data Systems has PMC certified managers as well as scrum certified. They have professionals who can drive the project from start to end and deliver the results.


Recording and creating artifacts of code and each stage is very important. Documentation of SDLC helps to track project status. Documentation helps to keep the project on track as well as helps for the smooth continuity of the project. Below are the documents Sigma Data Systems creates and preserves for all its software development projects.  


  • Scope

  • Additional feature approval version
    If new small features added along the run while development, it has to go through approval projects. These additional features are getting recorded and also approved by all Stakeholders. Its implications are also recorded on other relevant documents.
  • Status check report
    This is a weekly report which traces the status against the plan and actual completed work. This is shared with all the stakeholders on a weekly basis.
  • Developer notes
    These are the notes made by the developer within the code to understand the functions.
  • Code commit notes
    Every commit from each developer has these notes stating the details of the commits. This helps in version control and also gives the ability for quick rollback.
  • Test cases
    These are the cases made by our Expert QA professional. These are tested against each milestone-released version.
  • Bug reports with regression testing
    Each QA iteration generates bug reports which are fixed by software developers.
  • Release notes
    Every milestone/Sprint has released the delivery it carries. Sigma believes in agile methodology has frequent delivery planned. This helps stakeholders to get a view of the product while it’s in development.
