2. Four Steps in developing your OV-7 Step 1 - Identify the Product's Timescale
Decide on the timescale that this product is expected to represent (as-is, to-be, transitional)
Multiple timescales are often needed for each product; a separate OV-7 should be produced for each timescale that is needed .

3. Step 2 - Reference Existing Architecture Products
Review the following products to determine and extract the components that may apply to the OV-7:
OV-5 Activity Model
Interrelated activities
CV-1 Overview and Summary Information
External links
OV-2 Operational Node Connectivity Description
Operational nodes
OV-3 Operational Information Exchange Matrix
Information exchange requirements
OV-6a Operational Rules Model
Operational rules

4. Step 3 – Rationalise Data
Model Data
Conduct iterative discussions with analysts, users and other subject matter experts to fully understand the data requirements and to capture such understanding in a logical data model
Analyse Data
Perform iterative analysis to ensure that the logical data model is complete
Normalise Data
Review the key and non-key attributes of each entity type to ensure that the model is decomposed to the appropriate normalisation level

5. Step 4 - Illustrate Data Model
Graphically depict the components of the logical data model using the template provided
Create different views of the logical data model to depict the data requirements of specific subsets of the architecture

6. Delete the instruction slides when OV-7 completed
Template
A Process Logic diagram (IDEF1X) template has been provided, following this slide
Don’t forget to update all complementary products with information introduced in the OV-7
CV-1, CV-2, OV-2, OV-3, OV-5, OV-6a
Delete the instruction slides when OV-7 completed
