And how the Agile model could have helped us — Written by Manikkumar and Ray Mathew 1. Not estimating the difficulty of features before kicking off. Nor did we try to determine the number of features that could be completed within a sprint. Instead, every feature was given a standard time limit of two days, while the number of features selected for a sprint increased as deadlines loomed closer. Impact:

I’m a great fan growing object oriented code guided by test. Therefore, I created a small application demonstrating domain modelling skill and test driven development. Book References Before I begin, I do have five book recommendations on how to modelling the domain and last two for unit testing: Practical Object Oriented Design…

Preliminary Class Structure We’ll summarise some of the classes and responsibilities that we can identify from the previous exercises. This is not the complete list of classes we need to build. …

Following up from previous post, iterating through each identified class looking through funnel from solution view Command Holds the attribute of each command of LOGO Programming. Association of block-script to LOGO programming commands. Available Commands seems to have multiple responsibility, let’s break down by having additional clases and updating the existing one. “Available Commands” Loads all command

Solution Overview Preliminary Survey of Classes To provide a starting point for the development effort, we have to identify the objects and define their responsibilities. The central principle behind the allocation of responsibility is encapsulation; we do this by attempting to isolate the information or isolate the processing that must be done. …

Converting to Technical Problem statement We’ll set our goal by presenting several elements that make up a complete problem statement: a context in which the problem arises, the problem, the forces that influence the choice of solution, the solution that balances the forces, and some consequences of the chosen solution. I will summarize the approach…
