Information Systems Analysis 26 November 2019 Marking Scheme
This marking scheme has been prepared as a guide only to markers. This is not a set of model answers, or the exclusive answers to the questions, and there will frequently be
alternative responses which will provide a valid answer. Markers are advised that, unless a question specifies that an answer be provided in a particular form, then an answer that is correct (factually or in practical terms) must be given the available marks.
If there is doubt as to the correctness of an answer, the relevant NCC Education materials should be the first authority.
Throughout the marking, please credit any valid alternative point.
Where markers award half marks in any part of a question, they should ensure that the total mark recorded for the question is rounded up to a whole mark.

Answer ALL questions
Marks
Techno Wearables is a successful and popular company that manufactures and sells wearable digital products, for example, clothing, watches and glasses. During the last two years demand for its products has increased considerably.
Staff at the company include the CEO, managers of various departments, product designers, production operatives, administration staff, accountants, salespeople, warehouse operatives, technical staff and receptionists. All staff have access to the information system.
Techno Wearables needs a powerful and secure information system, however, a number of staff think that the current information system is out of date, slow, prone to data loss, prone to data corruption and prone to network crashes. It has also been affected by denial of service attacks and staff have reported malware.
A rival competitor has updated their information system and their improved customer services have attracted some customers from Techno Wearables.
The management team have decided that they must upgrade their information system as soon as possible to ensure that it is robust, reliable and secure. The company is financially secure at present and can afford to invest in a new information system and train staff.
Question 1
a) You need to choose which type of methodology would be the most suitable to 4 use to analyse the information system at Techno Wearables. Describe FOUR (4) factors that you will consider when making your choice.
Answer:
Award up to 1 mark for each bullet point up to a maximum of 4 marks.
• Whether technical aspects should be focused on/if a hard approach would be appropriate
• Whether human aspects/user needs should be focused on/if a soft approach would be appropriate
• Whether a combination of technical and human aspects/combined method would be appropriate
• The complexity of the current information system
• The complexity of the human aspects/user needs
• The advantages of each method
• The disadvantages of each method

Question 3
a) Object oriented analysis (OOA) could also be used during analysis at Techno 10 Wearables. Differentiate between an OOA and a soft systems approach to
analysis.
Answer:
The maximum number of marks to be awarded for this question is 10.
Award 1 mark for each bullet point up to a maximum of 5 marks.
Object oriented analysis
• If object oriented analysis is undertaken data and processes are
combined into objects
• Object oriented analysis focuses on technical aspects of a system
• Object oriented analysis considers the relationships between
objects, classes, etc.
• Tools used in object oriented analysis include functional models,
activity models, etc.
• If object oriented analysis is undertaken the system could be
developed more rapidly than if a soft systems approach is used
• If object oriented analysis is undertaken a system could be
developed more cost effectively than if a soft systems approach is undertaken
Award 1 mark for each bullet point up to a maximum of 5 marks.
Soft systems methodology
• If a soft systems approach is used data and processes are
considered separately
• A soft systems approach focuses on user/people aspects of a
system
• A soft systems approach considers wider issues in a social context
such as the usability of a system, job satisfaction, the structure of an
company
• Tools used in soft systems approach include rich pictures, root
definitions, concept models
• It could take longer to analyse a system using a soft systems
approach than if object oriented analysis is undertaken
• It could be more expensive to undertake a soft systems approach
Marks
than to undertake object oriented analysis
