Analysis and Design

• Business process analysis
• Requirements analysis
• Use case analysis
• Database design
• System architecture design
• Application design

During analysis, the first emphasis is a rigorous requirements-gathering process, which involves business process analysis and use case identification. Detailed requirements and outcomes are documented for each use case. These are reviewed separately by Professional Services QA staff to ensure they can be tested later and are quantifiable. This results in better, more clearly defined requirements, which are then outlined in a specification document that you can use to ensure that all requirements have been addressed in the design.

Once your plan is drawn up, the next step is the design. Design is the activity that transforms the requirements into a set of GIS software functions, each representing a piece of business logic.

Our project implementation approach utilizes specialized software to allow our design team to build directly from the requirements specification into a comprehensive design document that will guide our developers throughout the development process. The design activity also includes a data model and design, and, for clients with specific implementation requirements, a system architecture design that provides the basis for hardware and software planning and acquisition to support your planned GIS operations.
