What is Estimation?
- Prediction how much time we need to finish the project
What is Estimation?
- Prediction how much time we need to finish the project
- The hardest part is prediction tech-related things (browser incompatibility, conflicts) and soft-related parts (holidays, time loss when switching the context)
Why do we need estimations?
- We live from providing services to customers. Clients pay for hours we spend on a project

- We live from providing services to customers. Clients pay for hours we spend on a project
- We can ask customers for more hours during the development but it can make us unreliable

- We can ask customers for more hours during the development but it can make us unreliable
- We can predict the release date and depend on client’s needs we can hire 1-2 new developers
How the process looks like in Bejamas?

- The customer gives us materials for estimations. They could be very rough or detailed. If materials are detailed we can propose a more accurate proposal
