Diploma in IT Syllabus- Systems Analysis and Design

Systems Analysis and Design are core, interlocking, elements of systems development. Systems analysis is the process of turning a set of user requirements into a logical system specification. Systems design takes the logical specification and converts it into a set of designs that can then be implemented to create a working application. There is a range of activities that are carried out during these processes. Traditional approaches have attempted to define a set of carefully defined procedures that, if adhered to rigorously, should result in high quality applications. This approach is now challenged by more ‘agile’ approaches that stress the need to avoid overly bureaucratic, rigid, and costly development practices. Candidates will need to be familiar with the principles and applicability of both approaches.


  • To provide an understanding of the role of systems analysis and design within various systems development life cycles
  • To develop an awareness of the different approaches that might be taken to systems analysis and design
  • To understand the activities of the systems analyst and systems designer, and apply some current techniques

Prior Knowledge Expected:

  • Candidates are expected to be familiar with the material covered in the Certificate syllabuses.

What You Will be Studying:


  • Systems development lifecycle and position of SAD within it
  • Role of business analysts, system analysts and system architects
  • The characteristics and purpose of systems analysis and design methods and methodologies - including agile approaches such as Dynamic Systems Development Method (DSDM) and eXtreme Programming (XP)
  • The selection and adaptation of methodologies to deal with the particular circumstances of a development or application environment, including adoption/adaptation of existing software solutions


  • Stakeholder analysis
  • Requirements gathering techniques
  • Prioritization of requirements
  • Categorization of requirements, including the difference between function and quality requirements
  • Gap analysis
  • Business case and feasibility studies
  • Business activity modeling, including the use of data flow diagrams (DFDs) Use of prototyping, particularly as a method of requirements elicitation.


  • Use cases and scenarios
  • Identification of events, actors and use cases Use case realization
  • Entity relationship modeling (ERM)
  • Cross-referencing functions to data entities via Create/Read/Update/Delete tables Activity diagrams


  • Conversion of ERM to a relational schema Normalization and denormalisation
  • Identification of validation rules and other database constraints Views
  • Data migration issues, for example mapping between equivalent data items in new and old applications


  • OO concepts: classes and objects; encapsulation, interfaces, inheritance, polymorphism, message passing
  • Relating objects; associations and aggregations; Static modeling, including UML class diagrams;
  • Dynamic modeling: including UML interaction diagrams, UML state charts


  • Usability issues – this includes both ease of use and fitness for business purpose Interface design
