This OSM Readiness Tool presents three steps: 1. understanding the project environment, 2. recording knowledge, experience and capacity, 3. evaluation of OSM capability. OSM adoption can be enhanced though planning and engagement with stakeholders; including everyone contributing to the building project. Ideally all interested parties will be involved with OSM from the project inception. The OSM Readiness Tool is a mechanism to assist with gauging the availability of capability and capability sufficient for the project. It involves the systematic assembly of essential types of OSM knowledge, experience and capacity using a series of nineteen structured questions. Once entered onto provided spreadsheet templates, it becomes a database of information called the OSM_KnowledgeBank which can be used to evaluate and score available capability and capacity. Consideration of the opinions of all Project Team stakeholders will provide a more effective OSM project.
