It's not enough to have a team of talented IT specialists - they must be coordinated. Coordination is a job for a project manager.
Our project managers are responsible for risk management and mitigation, controlling the progress of the project, planning resources, and development iterations, reporting the status of the project to key stakeholders.
A project manager is responsible for the overall success of the project. Such an approach allows our clients to interact with one person and be sure everything is under control.
