As with any relationship, it took some time for us to gel, develop a common language and get a feel for each other's expectations and ways of working. However, in the later stages of the project, communication was greatly helped by the fact that the client and I sat (and still sit) together in the same office.

The Biggest challenge of the project has been the creation of mobile applications. Applications must be as usable as possible even without access to the Internet, which requires a departure from the comfortable technology used in the development of applications. However, we have reached the desired state after thorough analysis and careful design of the solution. Users do not even notice the fact that they are working without access to the Internet.

I especially appreciate the openness and cooperation of the customer - he was always ready to answer questions and listen to our suggestions and observations. The common goal has always been to design a solution that is as lazy as possible to implement, but at the same time provides as much freedom as possible and is easy to use - when sometimes this meant ultimately surviving the original design.

The main lesson and recommendation simultaneously - measure twice and cut once. It is always better to spend an hour on a proposal and a discussion, where inconsistencies are shown and clarified than to spend a day on implementation and then find out that the solution will not work and needs redone. Sharing our office with clients has also proven useful for us. The ability to quickly obtain or clarify a misunderstanding is priceless.
