Application development life cycle

SumatoSoft will take you through every stage of the software development process (SDLC) – from a business analysis stage through UX/UI and application development to deployment and ongoing support.

Application development life cycle explained

Application requirement analysis

The requirement collection is the first stage in web and mobile application development. It is performed by the senior team of business analysts, technical architects, and project managers together with all the industry’s business stakeholders and domain experts.

  • scope definition of the entire project;
  • planning for the quality assurance requirements;
  • definition of anticipated issues, opportunities;
  • recognition of the risks involved;
  • timeline definition.
Feasibility study

When the requirement analysis phase is done, the next step is to define and document software needs in the ‘Software Requirement Specification’ (‘SRS’) document. It has everything that should be structured and created during the application development life cycle.

There are five main types of feasibilities checks:

  • economic;
  • legal;
  • operation;
  • technical;
  • schedule.

Based on the SRS document, the team prepares the system and software design to define the IT system architecture. This design phase will be a base for the next coding phase.

There are two types of design documents that are developed.

1. high-level design (HLD):

  • brief description of each module and its functionality;
  • dependencies between modules;
  • database tables & their main elements;
  • architecture diagrams;
  • technology details.

2. low-level design(LLD):

  • functional modules logic;
  • detailed database tables;
  • complete interface detail;
  • complete modules input and outputs.

The next phase is coding itself — the most prolonged phase of the software development life cycle.

Peculiarities of the phase:

  • Developers should follow some predefined coding guidelines.
  • The whole development is divided into tasks for specific modules development.

Once some part of the software coding is complete, it is sent for testing, and the QA team starts testing the functionality to verify that the application works following the requirements.

The process is the following:

  • QA team finds some issues;
  • QA team sends them to the dev team;
  • dev team fixes the issues;
  • QA team rechecks the functionality.



Once the software is developed and fully tested, the final deployment process is launched.
QA team checks the software in the production environment.


After the release, the application continues its cycle following 3 possible ways:

  • bug fixing;
  • software upgrade;
  • enhancement with new features.


The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions.

They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.

Nectarin LLC aimed to develop a complex Ruby on Rails-based platform, which would be closely integrated with such systems as Google AdWords, Yandex Direct and Google Analytics.

I was impressed by SumatoSoft’s prices, especially for the project I wanted to do and in comparison to the quotes I received from a lot of other companies.

Also, their communication skills were great; it never felt like a long-distance project. It felt like SumatoSoft was working next door because their project manager was always keeping me updated. Initially.

We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us.

SumatoSoft is great in every regard including costs, professionalism, transparency, and willingness to guide. I think they were great advisors early on when we weren’t ready with a fully fleshed idea that could go to market.

They know the business and startup scene as well globally.

SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality.

Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.

Together with the team, we have turned the MVP version of the service into a modern full-featured platform for online marketers. We are very satisfied with the work the SumatoSoft team has performed, and we would like to highlight the high level of technical expertise, coherence and efficiency of communication and flexibility in work.

We can say with confidence that SumatoSoft has realized all our ideas into practice.

We are absolutely convinced that cooperation between companies is only successful when based on effective teamwork (and Captain Obvious is on our side!). But the teams may vary on the degree of their cohesion.

They are very sharp and have a high-quality team. I expect quality from people, and they have the kind of team I can work with. They were upfront about everything that needed to be done.

I appreciated that the cost of the project turned out to be smaller than what we expected because they made some very good suggestions. They are very pleasant to work with.

The Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.

SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly.

We’d like to thank SumatoSoft for the exceptional technical services provided for our business. It should be noted that we started our project’s development with another team, but the communication and the development process in general were not transparent and on schedule. It resulted in a low-quality final product.

SumatoSoft succeeded in building a more manageable solution that is much easier to maintain.

When looking for a strategic IT-partner for the development of a corporate ERP solution, we chose SumatoSoft. The company proved itself a reliable provider of IT services.

Thanks to SumatoSoft can-do attitude, amazing work ethic and willingness to tackle client’s problems as their own, they’ve become an integral part of our team. We’ve been truly impressed with their professionalism and performance and continue to work with a team on developing new applications.

We are completely satisfied with the results of our cooperation and will be happy to recommend SumatoSoft as a reliable and competent partner for development of web-based solutions
