Product development phases

Let’s start the exciting journey of digital product development.
We will guide and show how ideas and concepts are transformed into valuable solutions.

1. Inception

Every project starts with the Vision Document, where initial use cases, initial project glossary and project plan are described. This phase is crucial, as it defines core product features, business context, success criteria, risk assessments. Client concurrence on the cost/schedule estimates, priorities, risks and development process is checked.

Questions to be addressed:
  • Which platforms should be supported?
  • What technologies should be used for development?
  • How many third-party services should be implemented?

Its main purpose to estimate how much time and effort development will take.

Outcome:
  • Vision Document
  • Use case model
  • Tentative Architecture
  • Risks and rough planning

2. Elaboration

The analysis of project domain is performed, solid architectural foundation is created. Addressing most critical use cases, creation of refined plan of activities and estimates to complete the project. Performing intense feedback exchange with client to be sure, that actual resource expediture is acceptable.

Questions to be addressed:
  • Is the development plan sufficiently detailed?
  • Are vision and architecture stable?
  • Does the prototype show that the major risks have been addressed?
Outcome:
  • Revised project plan and risk assessment
  • Complete use-case models
  • Supplementary requirements
  • Design, test case, executable prototype

3. Construction

Starting developing all product features according to development plan. Quality assurance procedures are performed to be sure that all developed software features correlate with all use case models. At the end of this phase we will have the product, ready to be deployed to the users.

Questions to be addressed:
  • Is the product stable enough to be deployed to the users?
  • Client is ready for the transition into the user community?
  • Are the client expectations concur with actual resource expeditures?
Outcome:
  • All the features discussed on the previous stages are developed
  • Alpha, beta and other test releases
  • User manual is created

4. Transition

We run manual and automated tests and use various testing approaches during the entire development life-cycle to understand problems and bugs, enchance performance of the product and refine business logic and design. Also we address issues that have manifested after the deployment.

Outcome:
  • Final Testing
  • Release and rollout to customers
  • Plan for future releases

Time and Material

The Time and Material approach is focused on small and mid-sized businesses as it best suits complex and long-term projects. Ongoing projects that are at the testing or bug fixing stage and projects that require maintenance or support are also suitable for T&M. To start working y Time and Material approach, we estimate and agree on the particular scope of work, not the full project. This makes us mopre flexuble in time management and planning.

Outstaffing services

Outstaffing has a lot of advantages compared to in-house devops. Using outstaffing your company can hire a professional to solve specific tasks for one specific project. And if the skills of specific developer are no longer needed, there will be no problem letting him go. From this client can gain financial benefits, as specialists hired work on a per-project basis.
