When looking at undertaking a NPD (new product development) it’s always tempting to take short cuts in order make the development more attractive to management or a client. I’ve lost count as to the number of times that I’ve heard,
If we had the budget and time, of course we’d do it properly.
The problem with this, is that after doing this several times, it becomes the norm, and taking short cuts and in order to potentially save money usually leads to more problems in the long run.
Follow the yellow brick road
For those of you who remember the Wizard of Oz, following the yellow brick road led Dorothy to Emerald city. The NPD process is the same, and is nicely described on Wiki and many other great resources, so there’s no reason to ignore it. If you can’t get the information out of clients, propose a workshop or private session, where you can discuss all requirements and get a clear picture of the clients vision/expectations. Remember that before taking on any new development, you should undertake the task of defining specifications:
- User specifications: a document that specifies what the user(s) expects the product (e.g. software) to be able to do.
- Functional specifications: are requirements that define what a system is supposed to do. A functional specification does not define the inner workings of the proposed system, and does not include the technical details of how the system function will be implemented.
- Technical specifications: based on the Workshops, User and Functional requirements, you can finally construct the technical specifications documentation. This document(s) will contain all technical details of how the system will be implemented, and usually includes tables, equations and sketches of GUI layouts and hardware block diagrams.
- Review: the specifications and findings with the client, and make sure that they understand what they will be getting (i.e. the deliverables).
Although it’s tempting to ignore these steps and start playing with software, following the aforementioned steps keeps you focused and almost always leads to shorter development times.
