Passed OCMJEA part 2/3

[K. Tsang]

Howdy folks

Got results (144/160) today saying I passed the assignment/essay for OCMJEA.

Many thanks to the ranchers here with excellent tips and guidelines for the assignment, especially to MD

The assignment I had was Quick Computer.

I started the assignment almost immediately I passed MC exam in early March, registered on a Friday.

There were 5 use cases and I spent the time or weeks as follow:
- first weekend: read assignment, set up html files (index, risks, assumption)
- rest of March: (re-)learn UML, get familiar with my tool (Modelio), make notes and plan the design
- month of April: UML diagrams for class, component, deployment, and 5 sequence
- first half of May: finish off assumptions, risks html; didn't change diagrams, ask someone to review
- second half May: review the whole design from top to bottom, make changes accordingly, add bunch of html for NFR
- month of June: fine tune design, prepare for essay, take essay in end June

Throughout the whole process, I did found out doing this assignment is very similar to designing projects at work. The only difference is that at work you got to make the design work AND make your boss happy. However in the assignment, there is no boss (maybe yourself). Why I mentioned this? Cos you may not have taken the assignment much thought (too simple architecture) or taking it over the top (over-architecting).

At the early going, I practically did the minimal to get by (in diagrams and html documentation). But during the review, whole bunch of "taken for granted" things also put it so to make it explicit.

A word about Sheil's sample solution, I personally don't recommend candidates to reference it because it's incomplete and have several areas wrong (eg arrows in sequence diagrams).

Anyway on to my next endeavor and goal.

Hey man, I have the same assignment, I just started on "quick computer".

Any advice you can provide me?


I don't have idea where to begin, is like I can code it but I don't know what is the big deal about architecting it.

A little about my idea:


I started with Sequence diagrams for each one of the use cases, I consider right now to have only 2 actors(QC employees and suppliers).
I am thinking on using spring as backend framework because it make a lot of things easier and create a totally decoupled app using Angular as UI and only communicate to the backend through rest services.

I don´t know, is just that my plan after this is to create a diagram class based on the sequence but feel like is too simple, like I am missing something.



Anyway, hope you can give me as much advices as you can according to your experience.

By the way, what you mean by? :

- You mean the HTML files for the deliverable? Because my plan is to that at the end when I have a solution architected, right now I am creating my diagrams in "Enterprise Architect"
- How many assumptions you got? I almost finished the sequence diagrams and I have like 5, think is not a good number
- What do you think about my approach?
