Prototyping and communication

1. Prototyping and communication

The prototyping process in the early stages of developing a solution was more time- consuming and expensive than anticipated. Why could this have occurred?

1. There were logic errors in the initial algorithms.
2. The communication between the developer and the client was poor.
3. The modules to be incorporated in the solution were not readily available.
4. The developer selected an inappropriate programming language to implement the solution.
