Agile methodologies

Agile methodology has become our favorite tool for bringing order and efficiency to the development process no matter if we start it from scratch or engage with an existing project to improve it.

picture related to scrum


Scrum helps us to address complex adaptive problems, while productivity delivering products. Scrum is the best fit for the large projects of high complexity if:

  • The project requirements are not clear yet or client wants to start the development and gradually improve the product
  • The requirements are likely to change in the course of the development process
  • Client and service provider proactively discuss and adjust project requirements to achieve the best possible result
picture related to kanban


Kanban allows us to provide our clients with all the advantages of Scrum while eliminating some of its drawbacks. Kanban can be a good fit when:

  • The client has a large enterprise system with the huge amount of the legacy code
  • The development team is larger than 3-9 members recommended by the Scrum methodology
  • On-demand planning and tasks estimation can be introduced in favor of saving time for actual coding

Waterfall methodology

Waterfall approach is a good option to effectively manage projects that are relatively small in the scope of work and timeline. We use Waterfall when product requirements are well enough defined before the start of the project.

Fixed budget

If the budget for the project is set and control of the budget is one of the client's top priorities - waterfall is the best options by far.

Short project duration

Waterfall model is the best fit if the project duration is relatively short and the technology is well-understood.

Requirements are well-defined

Waterfall model is the best choice for those who do not plan to change requirements a lot after the development has begun.

Easier to manage directly

Each phase has specific deliverables and a review process and as the result, it is more attractive to those who want to manage directly.
