Nielsen usability heuristics. A second meeting (MT2) with stakeholders was then
organized during which the prototype was demonstrated and the design document signed
off. Consequently, the developer then implemented the system based on the final design
document. The mobile application was developed using Android studio. Arduino IDE
was used to code the sensing and actuating part as well as linking both the hardware and
the custom-built software. The system was tested using a white box testing strategy and
uncovered bugs were resolved duly.
Stage 3
IE installation: A second workshop (WK2) was then scheduled in week 14 whereby the
implemented system was demonstrated and explained to the focus group. The users then
had the opportunity of trying the system. Questions were asked to get their opinions and
recommendations to improve the current model. Feedback was generally positive.
However, the users suggested having an interface which would display the current
humidity and temperature values as well as a report displaying trends of water
consumption over a period of time.
5.2. Second prototype
Stage 1
Initial Scoping: Taking cognizance of the recommendations requested by the users, the
developer proceeded with a new set of requirements. Then, during an interview session
(IT3) in week 16, the users reported on their experience of using the system. They also
unanimously requested the ability to use finger print authentication to login into the
application. Mockups of the water consumption report was shown and feedback received.
Stage 2
Main Development: Based on feedback received, the developer then updated the
requirements specification document and consequently implemented the new
functionalities. Fingerprint authentication was added, a system’s overview display was
added for staying up to date at a glance and new report was implemented.
Stage 3
IE installation: After installation of the improved system, the primary users were allowed
to use the system for 3 weeks. They were also given a questionnaire with a set of tasks
to perform and to rate the system’s efficiency and usability. A workshop (WK4) was
scheduled in week 24 to discuss the results of the evaluations with the users. Work is
currently ongoing to improve the system based on latest feedback received. We also plan
to evaluate the system with a larger group of users in the near future.
6. Evaluating UC-IEDP against the proposed evaluation framework
An initial evaluation of UC-IEDP was then carried out with the evaluation framework
described in Section 4. The ethos of UC-IEDP is in how to put together technology and
create system which makes the infrastructure provide the required services [3]. There is
a strong focus on stakeholder involvement during the entire development process. UC-
IEDP is also informed by an ethical framework to embed ethics during development so
as to guard against violations of ethical principles. However, its focus is more on the
