Most of our data is collected in spreadsheets and documents with no central database
Your organization is early in the data maturity model. Maybe your program is new or is undergoing significant change. You’re likely to constantly be putting out fires. Processes around data management most likely reside in someone’s head and grant/annual reports take lots of time to assemble. Organizations at this stage find benefit in a purpose-built solution for key activities. For example, if volunteer management is a huge part of your day-to-day work, but you’re still figuring out exactly what you want to do with all the data you collect, you might consider a stand-alone solution (like Volgistics) or one that fits into a bigger enterprise system (Volunteers for Salesforce).
