How to Create Software: Key Tasks, Roles, Cost Factors

How to Develop Software - ScienceSoft

Delivering software development services since 1989 and practicing iterative Agile software delivery since 2007, ScienceSoft helps efficiently plan and build software products.

How to Develop Your Own Software Product: Summary

A development process for new software includes software ideation, planning, designing architecture, UX and UI, coding, testing, and deployment. When creating the lean working version (MVP) first, this process can take just 2–6 months.

A software development project team requires a project manager, a business analyst, UX and UI designers, front-end and back-end developers, QA and DevOps engineers. Depending on the project’s nature, additional talents can be required, e.g., data scientists, 3D designers.

In software product development since 1989, ScienceSoft helps design and build successful software products quickly and cost-efficiently.

Software Development Process Step by Step

Below are described the typical steps we at ScienceSoft take to complete application development projects. Some of the tasks can be skipped when you choose to develop an MVP. Also, different development methodologies (Scrum, Kanban, Waterfall, V-model, etc.) handle these tasks differently – they can be performed iteratively in parallel, or linearly.

Idea productization

Duration: 3 days – 3 months
  • Conducting competition analysis (competitors’ product features, pricing & monetization models, customer feedback analysis, customer acquisition strategy analysis, product efficiencies and drawbacks).
  • Identifying the target audience, understanding and analyzing their wants and needs, creating a software product concept.
  • Defining product differentiation and formulating a unique selling proposition (USP).
  • Defining customer acquisition, conversion, and retention strategies.
  • Defining the software monetization model.
  • Describing obstacles that can hinder entering a given market or industry sectors (including regulatory barriers) and suggesting how to address them.


Software planning

Duration: 2 weeks – 1 month
  • Defining and prioritizing detailed software features.
  • Creating a software requirements specification.
  • High-level software design:
    • App type/types (mobile, web, desktop).
    • Describing a list of software modules to build and specifying what functionality area each module covers and how the modules should interact.
  • Describing data and process flows between the target software and other existing software, planning integrations.
  • Creating the software development project roadmap with major milestones.
  • Drawing up a business case: conducting cost-benefit analysis, calculating NVP, ROI.

Best practice: We start with planning and delivering an MVP and then proceeding with rapid, incremental software evolution based on the frequent feedback from product managers, users, etc.



UX design

Duration: 1 week – 1 month
  • Conducting UX research to understand the mental models of the target audience.
  • Describing how a user will interact with the software product (e.g., what system response the user gets upon different actions).
  • Creating wireframes that demonstrate basic functionality and content layout on each screen.
  • Combining wireframes into a dynamic UX prototype of the application.
  • Performing the prototype user testing.


UI design

Duration: 1 week – 1 month
  • Deciding on the appearance of user-facing software parts (choosing a color scheme, icons for the buttons, menus, tabs and screen layouts of the application’s GUI).

  • Transforming software prototypes into full-color graphic interface mockups.

  • Creating a UI kit for the quick development of user interfaces.

We recommend our clients to invest in the unique UI design only if the design is a competitive software product advantage. Otherwise, we opt for default themes and focus on software functionality.

Best practice: At ScienceSoft, we usually take time to plan and ensure user interface consistency in different browsers, mobile versions on different screen sizes, and mobile applications on different operating systems.



Software architecture design

Duration: ~ 2 weeks
  • Detailed description of how functional modules of future software should work at the code level.
  • Detailed database design.
  • Defining integration approaches (point-to-point, middleware-based, iPaaS, etc.) between the different functionality modules.
  • Choosing the technology stack for the future software back end and front end.



Duration: 2-6 months to deliver the first working version
  • Establishing development and delivery automation environments (CI/CD, container orchestration, etc.).
  • Writing server-side code and APIs.
  • Turning static user interface mockups provided by UI designers into the fully functional GUI.
  • Conducting unit testing and static code analysis (by developers).

How to build software faster and at a lower cost?

  • Choose the technology platform (it will include a programming language and frameworks, architecture patterns, APIs, and more) based on a careful preliminary analysis of options. The development speed may differ 2 – 20 times.
  • Use cloud services (messaging services, analytics and AI services, image processing services, etc.) by well-established cloud providers, e.g., Azure and AWS.
  • Use trusted open-source tools and APIs.



Duration: ~30% of the project time (depends on software complexity, security and compliance requirements, the level of test automation, and more)
  • Creating a test plan with a testing scope, test types addressing all functional and non-functional software requirements, reporting procedures, etc.
  • Creating test cases and checklists.
  • Writing and running automated test scripts (API and UI tests).
  • Carrying out functionality, performance, security, integration testing.
  • Fixing bugs detected by testing.


Deployment and further iterations

  • Deploying software in the production environment.
  • (often for B2B products) On-site user training sessions.
  • Fixing bugs that users discover.
  • Planning improvements and new features to be added based on user feedback, product manager input, market trends, marketing strategy, etc.

Note: In iterative development models, all the described tasks will be cycled in 2-week – 6-month releases of new functionality.

Best practice: For our clients with B2B startup, we take time to plan and organize exceptional user support. It's important to get ready to anticipate customer challenges and questions regarding software setup and operations, proactively provide solutions to potential issues, show how users can achieve max value while using your product.
