Quantum LINQ

The challenge:  What software process do you use when developing your own software versus developing software for a company?  I am just starting the early planning stages of my PSP tool.  Do I follow the standard development process that I use at work, or cut corners?  I believe that whether you develop software for just your use or for a company, you should always follow the same process, without cutting corners.  I am going to use the PSP development process to develop my PSP tool.  The first step in the development process is to put together a conceptual design.  I am going to put together some prototypes for the UI – a smart client, a Pocket PC client and a web client.  I then will use the ORM capabilities of VS.NET to map out of the database design.  I will maintain a time log and a defect log separately until the tool is ready.
