During the project, it became clear that the client did not describe all the technical requirements in the terms of reference; it seems they were not aware of them at the time of writing the terms of reference and signing the contract. Throughout the work on the project, they introduced significant changes that were not documented in the terms of reference. I suggested creating another project to address everything that was not included in the terms of reference and, accordingly, did not factor into my budget and timeline estimates, but the client refused. We are closing the project with both parties having fully met their initial obligations.

Interesting project. Good client.
