Creating an Analyst Model

---

Before start creating a model of the organization you need to be aware of -
1. All the hierarchies of organization.
2. You must know all the dimensions that would be used to create the model. For example Countries in which the product is sold, Time, Categories of products, Different regions, Any other dimensions etc.
3. All the Business Matrics that you're going to use in the model, and which is the primary reason for creating the model.
4. You must discuss the goals of the application with management and CEO.
5. Create proper documentation of the model and get the approval of management.

After you've performed all of the above specified steps then -
0. Create a rough graphical model using the formal document above that would give you even better idea of the org. model. Fine tune it and do a mapping of what is to be taken as a D-List, D-Cube etc.
1. Create D-Lists of all the required dimensions.
2. Notice the hierarchy and decide which dimension you'd take to describe the hierarchy in the organization. It may be countries, Product or anything else.
3. Create that D-List as an E-List.
4. By using the D-Lists create the D-Cubes.
5. The data that is common for many cubes, create assumption cubes for that data.
6. Check the flow of data.
7. Create various D-Links to update D-Cubes.
8. Import data in D-Cubes (wherever required)
9. Finish the model and test it.
10. Check various D-Links and flow of data, and correct if something wrong.
11. Test all the flow lines of your model.
12. Add all the noticable things to your formal documentation.

TIP : You can use Enterprise Architect to create a paper model (High level - which could be later translated to technical model). It's a great tool with a lot of options. One other such tool is Microsoft Visio.
