System Analysis and Design Notes
A dedicated BCA World study page for this subject, aligned to the TU BCA 2025 curriculum units.
How to study this subject
For each unit, learn the definition, understand the process, practise one example, and finish by explaining the concept in your own words. Use the model questions after completing the unit notes.
Unit-by-unit notes
01
Systems concepts, information systems, and project feasibility
Revise the definition, components, workflow, common examples, and practical use of systems concepts, information systems, and project feasibility. Relate it to a small problem or case study from System Analysis and Design.
- Define the key terms and identify the main components.
- Draw or describe the workflow, architecture, formula, or process where relevant.
- Connect the idea to a practical BCA example and revise common advantages or limitations.
02
Requirements elicitation, analysis, modelling, and documentation
Revise the definition, components, workflow, common examples, and practical use of requirements elicitation, analysis, modelling, and documentation. Relate it to a small problem or case study from System Analysis and Design.
- Define the key terms and identify the main components.
- Draw or describe the workflow, architecture, formula, or process where relevant.
- Connect the idea to a practical BCA example and revise common advantages or limitations.
03
UML use cases, class, sequence, activity, and state diagrams
Revise the definition, components, workflow, common examples, and practical use of uml use cases, class, sequence, activity, and state diagrams. Relate it to a small problem or case study from System Analysis and Design.
