"The important thing is not to stop questioning."

- Albert Einstein, Physicist (1879-1955)


During Information Development activities, Envizion recommends that formal reviews take place, to be sure that the business requirements, performance goals, and integration goals of your Information systems initiatives are met and aligned. These are good opportunities to pro-actively identify, document and address critical issues as they arise during the information development lifecycle.

Envizion can work with your organization during the Information Development lifecycle, to determine what reviews are appropriate, when they should take place, and what inputs and outputs (deliverables / validations / approvals) are needed to move forward.

 

For the Conceptual / Logical (Data Model Development) phase, Envizion can help to:

  • Coach, facilitate, or participate in a Data Model review, with objectives to evaluate the completeness, structure, clarity, quality, and consistency of the model and all its components
  • Review the model to see if it effectively uses the common business vocabulary, Master and Reference data, and common classification schemes
  • Evaluate the model for correspondence with, and support of, business processes
  • Determine if the components of the model follow standards and have clear definitions, understandable by business people
  • Evaluate the model for alignment with the organization’s Information Architecture
  • Identify and document any issues which may have implications during further development activities

 

For the Physical (Database) Design phase, Envizion can help to:

  • Coach, facilitate, or participate in a Physical Database design review to evaluate the Data Model review to evaluate the completeness, structure, clarity, quality, and consistency of the physical design and its components
  • Determine if the key structures and relationships (foreign keys) are defined correctly in terms of Referential Integrity and Delete Rules
  • Evaluate the model for correlation with the main transaction, with a focus on performance aspects
  • Evaluate all components of the physical model for compliance with naming and abbreviations standards, to ensure accurate meta-data
  • Evaluate the physical database design for integration with other data enablement services, i.e. their alignment with the Information Platform
  • Evaluate the design for requirements of availability, recovery, archiving and purging

 

Following the phase-end reviews, there should be appropriate validation and approval, by the right stakeholders.

Reviews are key milestones in the Information Development Lifecycle, and Envizion can add value at the right time – by coaching, facilitating, or participating – actively, with expert knowledge and an objective viewpoint.
