Vocational Scenario or Context
You have just started work as a junior system analyst at System perfect a system analysis and design company.
You have been asked to join the team that will design and develop a
new online fishing licence renewal system for Iceland Waterways.
The team consist of a Project Manager, three senior system analyst,
one other junior system analyst, six system developers and two
software testers.
Fishing licence are currently renewed at local fishing equipment shops
through a manual system that is very expensive to maintain and
update and is not always accurate.
Iceland Waterways want to make the renewal of the fishing licence
more convenient and efficient through an online payment portal and
has requested that you carry out focus groups with the key stakeholders to investigate the user requirements. The stakeholders are also required to test the online payment portal.

The online system should be easy to use, capture all of the required
information and link to an online database of fishing licence records,
process payment and generate the fishing licence. An email reminder
that a fishing licence has expired is also required.
Task 1:
The Project Manager has asked you to work with the other junior system analyst to present a report to Iceland Waterways that explores software development models and systems analysis tools and techniques and their suitability for modelling business processes requirements of the fishing licence system.
Your first task is to write a report evaluating the principles of system methodology and the different stages of software development life cycle (SDLC) and the alternative approaches available, including:
1.waterfall method
2.spiral development
3.prototyping
4.incremental development.
Evaluate the nature and features of different system methodologies:
traditional structured methodologies structured systems
analysis and design (SSADM)
agile methodologies rapid applications development (RAD)
dynamic systems development (DSDM)
Finally, compare the use of the applied software development lifecycle
model and systems methodology techniques in the problem solving
process against alternative options and evaluate in regards to:
- Object-oriented techniques: unified modelling language (UML®), analysis models such as cases, analysis class diagram.
- Structured techniques: entity relationship diagram (ERD), logical data structure, process such as data flow diagram (DFD), time such as entity life history, models.
- Computer-aided software engineering (CASE) tools, e.g. system requirements specification documentation, data dictionary, screen design for data input, decision table checking.
