Hi all, I took the Nexus / SPS open assessment, and have trouble with one of the question / answer combinations.

Could someone please elaborate and explain why this is the correct answer?



Question: Management planned for 200 developers to work on a new product. Prior to forming teams, an overall architecture and integration design is needed. Which of the following employs Scrum / Agile most effectively?



Answer 1: Form one or two teams of best developers to create a foundation that represents the non-functional requirements and also several high value functions. Than increase the number of teams using the shared architecture



Answer 2: have the best designers and developers create an appropriate design and architecture. Include design models that the rest of the developers will include while implementing features.

Answer 3: Form a team of architects and designers. This team will serve as consultants to the other teams

Answer 4: Design and instantiate an appropriate SOA. Train Development teams on how to consume the shared SOA.

 

Spoiler alert: the correct answer is 1. But why? And why not one of the others?

Which of the available answers would allow empirical process control to be most swiftly and thoroughly established?

But why not answer 2 than? Where is the "critical" difference between 1 and 2?

Answer 1 allows for the architecture to emerge empirically by developing releasable non-functional requirements and high value functions. 

Answer 2 creates designs and models based on assumptions about the product, not based on any working software.

I would argue that the question is written poorly:

Prior to forming teams, an overall architecture and integration design is needed. 

Form one or two teams of best developers.

@Xander, where is this poor question formulation introduced: actual exam question or your recollection?

Thanks
