Chapter 3: Requirements and analysis. This should state, in a more detailed way, the objectives of the project by requirement and the analysis should break the problem down into manageable steps. There may be more than one suitable approach; the analysis may cover more of the area than is finally implemented. Suitable diagram-techniques (e.g. UML, other drawings) should be used where appropriate. If a method is applied selectively, explain which parts were used and why. Experimental projects should pay careful attention to control conditions, samples selected, etc. to ensure a valid result. Testing and evaluation should be given due consideration. It is important that you state how you will evaluate your work. For a design project it is appropriate to consider testing at the same time as specification.
