Chapter 15: Present and Defend – Second Mock

In this chapter, we will continue to create an end-to-end solution for our second full mock scenario. We have covered most of the scenario already in Chapter 14, Practice the Review Board – Second Mock, but we still have plenty of topics to cover. We will continue analyzing and solving each of the shared requirements and then practice creating some presentation pitches.

We will follow the same sequence that you will go through in the real exam. After the presentation, we will move on to the Q&A and practice defending and changing our solution based on the judges' feedback.

After reading this chapter, you are advised to reread the scenario and try to solve it on your own.

In this chapter, we're going to cover the following main topics: 

• Continuing with analyzing the requirements and creating an end-to-end solution
• Present and justify your solution

By the end of this chapter, you...

Continuing with analyzing the requirements and creating an end-to-end solution

We covered the business process requirements earlier. By the end, we had a very good understanding of the potential data model and landscape. We have already marked some objects as potential LDVs.

Next, we have a set of data migration requirements that we need to solve. Once we complete them, we will have an even better understanding of the potential data volumes. We can then create our LDV mitigation strategy.

Let's start with the data migration requirements first.

Analyzing the data migration requirements

This section's requirements might impact some of your diagrams, such as the landscape architecture diagram or the data model.

Let's now start with the first shared data migration requirement.

PLU has over 80 million customers in its legacy CRMs. The data is expected to contain a significant number of duplicates

If we analyze this requirement, we can identify the following...

Presenting and justifying your solution

It is now time to create your presentation. This is something you would have to do on the go during the review board as you would likely consume all 3 hours creating the solution and supporting artifacts.

As we mentioned before in Chapter 13, Present and Defend – First Mock, you need to plan your presentation upfront and use your time management skills to ensure you describe the solution with enough details in the given time. We will discuss some time-keeping techniques in Appendix, Tips and Tricks, and the Way Forward.

You are now familiar with the structure of the board presentation. We start with the structured part of our presentation, and then we switch to the catch-all mode. As a reminder, these two different presentation phases include the following:

• The structured part: In this part, you describe specific pre-planned elements of your solution, starting with an overall solution introduction, including a brief walk...

Summary

In this chapter, we continued developing the solution for our second full mock scenario. We explored more challenging data modeling, accessibility, and security requirements. We also created comprehensive LDV mitigation and data migration strategies. We tackled challenges with reporting and had a good look at the development and release management process and its supporting governance model.

We then picked up specific topics and created an engagement presentation pitch that describes the proposed solution end to end. We used our diagrams to help us explain the architecture more thoroughly and practiced the Q&A stage using various potential questions.

Congratulations! You have now completed two full mock scenarios. You can practice solving these scenarios as many times as possible. You can also try to add or remove requirements to them to make things more challenging. The mini scenarios we used in this book are also handy to practice a shorter version from time to...
