Can I build my own PRM system?

There is always a tendency to consider “build it yourself” or building a solution inside an existing enterprise CRM. This is particularly true for large programs and companies with significant IT resources. This approach can result in the exact system you want with practically no compromises for vendor limitations. It is, however, unquestionably the most expensive alternative, usually by a factor of at least 5x – 10x. Beyond cost, consider the requirement and commitment to continue to invest after the initial launch. Your PRM system may be exactly what you want on day one, but the only way to keep a partner community engaged is to keep the system fresh. No business process is going to remain static for long. Consider allocating approximately 25% of the original cost to build the system as an annual technology maintenance.
