From the lecture, you know different types of IT organizations. Please name InsureMe’s IT organization type and explain the organization type’s characteristics. Further, name one advantage and one disadvantage for this IT organization type.
It is a decentral IT organization. The characteristic is that each business unit has its own IT. Pros are individual responsibility, and controllability. Contra is the application jungle.
Draw the central IT organization and provide its characteristics. Name one pro and con.
Draw the decentral IT organization and provide its characteristics. Name one pro and con.
Draw the federal IT organization and provide its characteristics. Name one pro and con.
What kind of IT organization type would you recommend and why? Name two factors that have to be considered when making organizational change decisions.
I recommend the Federal IT organization because it is the best of both worlds. Decentral, but with an organizationally anchored governance for harmonization. You should consider history, and leadership culture.
Describe what an EA model is and name one advantage and disadvantage and one challenge for creating one.
EA model creates a common language for business and IT.
It has the pro that it visualizes the EA and makes it accessible to different stakeholders. One challenge is to get to the planned from the target EA model.
One disadvantage of an EA model is that it can be complex and difficult to create and maintain, particularly for large organizations with multiple departments and systems.
One challenge in creating an EA model is ensuring that it is both comprehensive and accurate.
Shortly explain the difference between the current, planned and the target EA architecture.
Current state of the EA reflects current architecture. Planned state of the EA is derived from planned and budgeted projects. A target state of the EA describes an ideal state.
Name the 3 anti-patterns
Don’t boil the ocean.
Don’t build an ivory tower.
Don’t be a PP architect.
Explain “Don’t boil the ocean” and provide recommendation to over it.
You should not create a meta-model and then a corresponding EA model by collecting the necessary data. The problem is that data collection efforts are expensive and take time. You have too many EA models that are neither in-depth nor broad. Both are needed.
–> The recommendation is to start with a small model and enlarge it when needed incrementally.
Explain “Don’t build an invory tower” and provide recommendation to over it.
Instead of having all the knowledge centralized, not talking with the stakeholders when the models are built, not talking to agile teams etc.
-> you should establish a shared language, request feedback from agile teams, and participate in agile events.
Explain the BCM use case: Cost vs. User Count Ratio
Identify inefficient capabilities by checking each application’s costs against user count . You can use internal users but also customers.
