aim of this phase is to formulate and define a system concept that will best satisfy valid
user needs. Therefore, the main objectives of the concept development stage are [17]:
To establish that there are valid needs for a new system that is technically and
economically feasible.
To produce and explore a spectrum of ideas and potential system concepts and
formulate a set of system quality requirements. Use of modelling and
simulation techniques is highly recommended to inform the decision.
To select the most relevant system concept, define its functional and quality
characteristics, and develop a detailed plan for the subsequent stages of
engineering, production, and operational deployment of the system. Decisions
are made largely on analyses, simulations and functional designs.
The first activity during the engineering development stage is to identify and
minimize development risks. In particular, any new technology that may be required is
validated to avoid or mitigate risk of failure during later stages. Detailed system design
specifications and test plans for the selected concept are then produced taking into
consideration operational, quality, cost and schedule requirements. Following this, the
system’s functional design is implemented into hardware and software components using
a variety of tools and methods. Component testing may take place concurrently. Finally,
the components are integrated to produce a production prototype which is evaluated in a
realistic operational environment to ensure that it performs as expected and user needs
have been met satisfactorily. This is generally followed by formal design reviews. In
addition, the end users get the opportunity to provide crucial feedback to the system
developers and any implementation deviations are rectified. The postdevelopment stage
is mostly concerned with providing support and maintaining effective configuration
management strategies after the system has been released for production. Critical bugs
or unanticipated system failures are carefully addressed and monitored. Provisions are
also made for training users to use the system.
5. Application of the UC-IEDP methodology
The UC-IEDP methodology was used to build a low cost smart irrigation system
for small-scale planters in Mauritius. It serves as a guide to developers towards the
development of IEs [3]. It consists of three core stages represented as iterative loops:
initial scoping, main development and IE installation. It is also guided by an ethical
framework which ensures that ethical issues are properly managed. The aim of the
project was to provide a more efficient water irrigation system whereby wastage is
avoided as much as possible. Existing solutions are too expensive. The project started in
October 2018 and is expected to complete by end of April 2019. The system consists of
humidity and temperature sensors, a microcontroller, and a solenoid valve as an actuator.
Users can also monitor and control the system through a custom-built Android
application that connects via Wi-Fi to the microcontroller. A focus group consisting of 3
planters as primary users participated in the development process. They are also the
principal stakeholders in the project.
Stakeholders were involved through a variety of activities such as face-to-face
interviews, questionnaires, workshops and project pilots. Successive prototypes were
generated following feedback from the focus group. A timeline of the focus group
