Frequently asked questions

How do you ensure the quality of a software product during development?

We have several aspects that serve to ensure the high quality of the final product: 

  • First, we adopt a quality assurance strategy where we agree upon the necessary quality of the software from the beginning. The quality is measured by the acceptance criteria which are a set of predefined conditions that a software product must meet to be accepted. 
  • Secondly, we always check that the final software will go online without critical bugs and blockers. 
  • Thirdly, we thoroughly approach the initial stages of the business analysis and system architecture, laying the solid foundation for the whole project. We identify and address any issues proactively, ensuring that the final software meets the highest quality standards.
How does XtremeProgrammers help in the ideation and concept development stage?

In the ideation and concept development stage, SumatoSoft offers a team of experienced business analysts, product managers and software developers who can run proof of concept or refine the Client ideas.

SumatoSoft is a reliable software development consultant that can help to lay the solid foundation for the project before its actual beginning. We conduct in-depth market research, analyze competitors, draw user personas, check the regulatory compliance of the idea, draw the product vision, and more.

What is the role of UI/UX design in software product development?

UI/UX design is an integral part of any product development. Even if there is no designer on the project and the development team uses a UI library for all interfaces, it’s impossible to release the software product without considering the UI/UX aspect. Here are a few examples of just general UI/UX best practices: 

  • clear website navigation so the user won’t hunt for basic links like “Contact”, “About us”, or “Services”; 
  • a simple user interface with few and only necessary modals and pop-ups so the website won’t bombard users with multiple modal windows before they have even had the chance to view the content;
  • optimized layouts for mobile resolutions;
  • consistency in design when with the same color schemes, typography, and layout structures.

And many others. A well-conceived UI/UX is what encourages users to come back to the website and use it.

How does XtremeProgrammers ensure the security of a software product?

As one of the most professional software product companies with 13 years on the market, we came up with several sets of strategies, techniques, rules, and guidelines to ensure the robust security of the software. We adopted a flexible approach in our software development services, fitting our security efforts to the project requirements. Here are the components of our security approach: 

  • Principle of least privilege – we grant users permissions to modules, processes, and components that are just enough to perform their functions. 
  • Threat modeling – we conduct threat modeling sessions to identify potential security threats and vulnerabilities. 
  • Adherence to coding standards – we strictly follow coding standards provided by OWASP, the SANS institute, and our best practices in security. 
  • Static and dynamic code analysis –  we run both these security tests if necessary. 
  • Penetration testing and security audits – we have the expertise to implement both these activities that allow to identify security vulnerabilities and assess the application’s compliance with security standards and regulations. 
  • Efficient data encryption – we encrypt data both in the database and in transit using strong encryption protocols. 
  • Robust authentication methods  – we can implement multi-factor authentication to prevent unauthorized access and data breaches. 

These are only some of the guidelines for our security standards.

How do you reduce the risk of App Store or Google Play rejection for a Generative AI app?

Our post-launch support is a flexible service that we can adapt to the needs of the specific project and business. The basis of post-launch support service is bug fixing and comprehensive training on the solution where we share all relevant knowledge on the project.

Then, we can extend the range of services and include feature enhancements, technology stack updates, software scaling, 24/7 monitoring to ensure the software performance and health.
