How We Do It

PriorIT Consulting, LLC follows the Open Group Architecture Framework (TOGAF®) project implementation metholodogy. TOGAF is a detailed method and a set of supporting tools for developing an enterprise architecture. The key to TOGAF remains a reliable, practical method - the TOGAF Architecture Development Method (ADM) as shown by the following figure - for defining business needs and developing an architecture that meets those needs, utilizing the elements of TOGAF and other architectural assets available to the organization.

The TOGAF ADM is then interpreted and used as the basis for planning, designing, implementing and maintaining a successful enterprise GIS Program through Project lifecycles as shown in the following figure below.

The above approach can support both the agile and waterfall approaches, which ever the customer prefers us to use. However, which ever approach is used, we recommend that each activity above has both technical and management reviews and lot's of customer interactions.
