Service Planning Sheet
The Service Planning Sheet works well as a replacement repository in the start phase of an SOA. As long as you have less than 25 services and a maximum of three parallel projects, you can manage your services as lists from Excel spreadsheets. The contents can at a later stage be imported without any great difficulty into a professional tool with which you can manage the life cycle of the services.
Service Operation Sheet
For every service, one or possibly more operations must be described. This can be done with the Service Operation Sheet.
