24/7 VIDEO is a video library. The store was founded by a group of young entrepreneurs and has
been in operation for last two years. Unfortunately, the library is fighting for its survival because
of insufficient members and low rental rates. From a business point of view, one thing the library
must be concerned with is increasing members, which will help them in revenue growth.
Currently they are managing their library system offline using Microsoft Access Database and
payment is not integrated with the system making the life of the members and staff difficult. At
present, their business is mainly focused on loaning videos over the till, however the store is
seriously considering of having an online portal where users can watch videos online. Their
website also needs to have the facility of online registration, booking and payment system.
Members can book and pay online and get the items collected from the library. The company is
looking for a packaged solution, where they can have system which can be used online or
offline. The system must integrate finance, library record and member management with a goal
of business expansion and revenue growth.
The company has hired your information systems consulting firm to look into the possibility of
developing a library information management system. This system will address the company’s
issues with offline and online requirement. As a system analyst working for the company, you
are required to take the project on board.
LO1: Understand different systems life cycles
 Evaluate different systems lifecycle models (e.g. Systems Development Life Cycle (SDLC),
Rapid Applications Design (RAD), Extreme programming, Spiral, Agile, Dynamic Systems
Design Methodology (DSDM), Waterfall and Prototyping etc.) that can be followed while
developing the information system for the above company. Select one and justify your
selection by comparing with other models.
 Discuss the importance of following lifecycle stages within different models in a systems
investigation (e.g. feasibility study, analysis, design, implementation, testing, review) or
(analysis, design, implementation, maintenance, planning))

LO2: Understand the importance of a feasibility study
Feasibility study is one of the most important stages in the lifecycle. If accurate data and
information is not acquired from users about the existing environment, problems, or requirements
for a new or revised system, then the investigation can be flawed. At this stage, it is important to
consider all stakeholders in any activity because failure to do so can often be one of the reasons
why new systems do not fulfil the stated requirements and thus project delay or even failure.
Prepare a feasibility document for the above company. You are expected to use a range of
information collecting and various fact finding techniques (interviews, observation, investigation of
documentation, questionnaires, focus group) in order to formulate project specification based on
requirements of the above company.
You should discuss the various components (purpose; structure; intended audience; outcomes) of
a feasibility report and assess the impact of different feasibility criteria on a systems investigation.
Feasibility criteria such issues as legal, social, economic, technical, timescales and organisational
constraints should be discussed.
LO3: Be able to perform a systems investigation
In this part of the analysis you are required to undertake a systems investigation to meet a
business need, use appropriate systems analysis tools and techniques to carry out a systems
investigation. Identify requirements in relation to stakeholders; requirements identification;
requirements specification (e.g. scope, inputs, outputs, processes and process descriptors;
consideration of alternate solutions; quality assurance required). You must consider relevant
constraints specific to a given activity e.g. costs, organisational policies, legacy systems,
hardware platforms etc.
You should prepare a design document to support a systems investigation. The document should
address background information, problem statements, data collection process and summary with
recommendations.
The design document should present context diagram, detail data flow diagrams, data model for
the proposed system. Select an appropriate model for the representation of your data model and
evaluate how user and systems requirements have been addressed. Your project may apply ER
or UML modelling technique to represent the data model and should be underpinned with
appropriate theory and practices. The data model should represent all the relevant business rules,
integrities and validation procedures. Other investigation and design techniques to consider
include BSOS (business systems options) and TSOS (Technical systems options), quality
considerations, e.g. Total Quality Management (TQM) for the company. You may add facts that
you gathered during interview and observations.
Presentation
As part of the overall assessment of this assignment, the students need to prepare an
oral presentation of their individual work. You will use power point presentation or similar
presentation package of your choice. The presentation will last no more than 15 minutes. You will
be marked on content, presentation style and clarity of delivery.
