Excel Magic Quadrant

When you are working in the IT business you have come across the magic quadrants from Gartner. Gartner uses this way of visualizing prefects or vendors and giving them a place in the market. Gartner states the following about the magic quadrant: "Gartner's Magic Quadrant research methodology provides a graphical competitive positioning of four types of technology providers in fast-growing markets: Leaders, Visionaries, Niche Players and Challengers. For emerging or mature markets, Gartner's MarketScopes are the best tool to help clients understand how the status of an emerging or mature market aligns with their own state of maturity and future plans."

My personal opinion is that the magic quadrant is great to show the information in a single graph, and combined with the knowledge from Gartner and information from your own company you can make a solid decision as a CxO. However, the magic quadrant way of visualizing can be used for so much more than only they way Gartner is using it. I am currently falling inn love with this way of representing information and I recently started to use it to visualize for example the maturity of systems in combination with the business value they represent. This is working great during meetings as you can show a lot of systems in one graph in a way that is also understandable for none tech people.
The idea came after some talks on how to represent data in a none-tech way and we came up with a gartner magic quadrant way of representing the information. Considering you will most likely have only a limited number of tools on your laptop you will most likely be bound to the options to draw such a image in Microsoft powerpoint or to make a graph in Microsoft excel. I have used Microsoft Excel for this task because I could make a framework which can be used for all future graphs I will need. below I explained how this can be done, please note in the example I will be using Microsoft Excel 2011 (version 14.0.2 build 101115) on a mac. The point that it is on a mac will not be that hard to overcome, only the graphs look a little different however the 2011 part you might want to consider if something is not working as expected.


Step 1.
first step is to get your data in a correct format. if you like to create a framework for future use you might want to reserver some space in your sheet where you can enter the data. On the X axis you please reserver 2 columns for your data. one for the values of (in the example of a Gartner magic quadrant) "completeness of vision" and one for "Ability to execute" On the Y axis you can place the product/vendor names. Before you enter your data you should think about the scale of things, you want to have a pre-defined scale on which you will be plotting 0 till 10 might be a good option however you can pick any scale you like. I have picked 0 till 7 due to some internal metric which is based upon this scale. This way you should en up with a nice formatted place to store your data, something like the example below:

Step 2
Your second step would be to introduce a standard bubble chart. this is standard within excel, the thing you need to take into account is that you will need to do some extra setup when selecting your data. you need to create series for every line of data you created in step 1. If you would create a framework you can do a lookup to the cell for every value of the X and Y axis and the name. You will end up with something like the below example.
Step 3.
A bubble chart is by default using a automatic horizontal and vertical axis scale which you do not want to have in this example. You want to devoid your graph in 4 equal parts where everything below a certain figure is in a certain area of your graph so you have to unset the auto scale function on your axis. Tis can be done with the format axis option of your chart. It is advisable to set the max 1 point higher than the scale you defined in step 1 and the min one point lower. This ensures that a bubble which is on the lowest (or highest) part of your scale will not be shown half because it is falling of your plot area. In the below example you can see the settings for a scale 0 till 7. After you have set you scale you want to remove the axis from the plot area so you will not see it (or need it).
Step 4.
In principle your magic quadrant is now done. All you have to do is some design steps. You should remove the grid lines and draw a box around your plot area. After that you need to draw a cross with vertical and horizontal lines from the middle of your box. Now you can see the magic quadrant coming to what you expect of it. From a design perspective you might want to shrink the size of the bubbles and add labels to it and position them on the left, the right, the center or any other position in respect of the bubble you feel conferrable with. You might want to do all kinds of other design things however the result till now will look something like the below example:

solved: there are no valid navigations for this responsibility

Recently I tried to setup some roles for Oracle e-Business Suite (11.5.10.2) by using Oracle User Management. To be able to do so I granted myself the User management responsibility. However, when entering the responsibility I encountered a error stating "there are no valid navigations for this responsibility" as shown in the screenshot below.

As it turns out you need to do some other things when you want to grant yourself this responsibility You have to grant yourself the rights via user management by using the sysadmin account. It looks like a catch 22 however this is in a normal situation something you only need to do when you setup your system the first time and would like to make use of Oracle User Management. In a normal situation (not a test instance) you would provide one user the rights to access this and have this user propagate the rights to other users from within his account.

Looking At Oracle metalink you have to undertake the below steps and indeed, this is the solution for this issue;

1. Log into the applications as SYSADMIN User.

2. Choose User Management responsibility.

3. Navigate to Users web page.

4. Search and find the user you want to inherit the Security Administrator and Customer Administrator Roles.

5. Click on Update Icon.

6. Click on Assign Roles button.

7. Find and choose 'Security Administrator' Role.

8. Apply.

9. Repeat the Steps (6-8) for 'Customer Administrator' Role.

10. Log as the user who was assigned User Management Responsibility and facing the issue.

11. Retest the issue.

12. Migrate the solution as appropriate to other environments.
