2 Write a motivation to management in which you explain what your concerns are in
using the formal methods model in the specification of your registration system. (6)
Concerns are highlighted on page 92 (Pressman, 2005). You need to highlight that in a
registration system costs are always an issue, and using a formal method may lead to more
costs, which management may want to prevent. Also, you may argue that the university has
no software developers and therefore needs either to appoint developers or to train existing
staff. Thirdly, since the users of the registration system are not technically sophisticated,
using formal models as a communication mechanism may be problematic.
3 Discuss how you can use adaptive software development in the software
development of a registration system at the university. (10)
Use the guidelines on pages 114–116 on adaptive software development and relate how the
three phases – speculation, collaboration, and learning – will play a role during the
development of a registration system using adaptive software development as a technique for
building the system. The following is an example of a good answer sent to us by Leanne
Buckus, which incorporates the registration system into the phases given for the Adaptive
Software Development Model:
3.
The 3 phases of the Adaptive Software Development (ASD) Model for the software development of a
university’s registration system would be
i) Speculation Phase – in this phase:
The registration project would be initiated
The mission statement of the customer is determined i.e. to register South African and foreign
students both online and through a Contact Centre, using a simple, efficient and effective
process
The scope of the project would be established – inclusions and exclusions in the project
The project constraints are established – delivery dates, – which campus, which users, which
students
Basic requirements are established – the high level registration requirements to determine the
project iterations
ii) Collaboration Phase – in this phase:
Workshops and JAD sessions have to be arranged to determine the detailed requirements per
cycle, develop a design to support the requirements
Develop and deliver a solution per release cycle
iii) Learning Phase – in this phase:
As part of each cycle, focus groups must be scheduled to determined whether the release to
be delivered meets the business requirements
Formal technical reviews must be conducted on the software components to ensure that
improvements in quality, design etc are learned and incorporated for future
Postmortems must be done by the ASD teams to look at the own performance and process
with the intention of learning and incorporating those lessons in future
4 What questions must be asked and answered in order to develop a realistic
project plan for a university registration system? (7)
