ANALYSIS
This section has a total of 12 marks allocated to it, which are spread out
amongst its different aspects. The vast majority of the work in this section is
based upon discovering how the present (old) system provides a solution
to the problem. However, there will inevitably be some extra comments made about
the added requirements or wishes of potential users for the new system.
ANALYSIS - Identify a Problem
This sub-section has a total of 4 marks. The marking points are hierarchical
but this time instead of adding statements every mark, words like ‘list’ are
replaced by words like ‘describe’.
1 mark
- Identify a problem.
- The candidate must provide evidence that they have identified a problem.
If they are not attempting to solve a problem that they have decided upon,
they have to include in their work a list of problems and on it they will
indicate their choice.
- Outline the nature of the problem.
- Candidates will make a list of the problems, which are
being faced by the user of the current system. Throughout, the “user” of a
system should be thought of as the person who operates the system e.g. a
salesperson using a system to assist a customer and not the customers
themselves. One such problem could be the user has difficulty in knowing
whether she has cars of a certain colour in stock.
2 marks
- Outline the user’s requirements.
- The candidate makes a list of features of a system which the user
requires. The candidate might list features which the user needs to be able
to find out easily e.g. if there are any arctic blue cars in stock. Another
feature is the ability to find the phone numbers of customers who want a
particular car when it comes into stock. Several of these points would need
to be made by the candidate.
3 marks
- Describe the nature of the existing problem.
- More detail has to be given to each item on the list of problems being
faced by the user of the current system. One example, although there would
have to be several, could be a description of how each part of the current
system operates such as how the user currently looks for all the red cars.
- Describe the user’s requirements.
- Some detail has to be given to the list of the owner’s requirements.
This will go further than just saying that the user needs to be able to find
all the red cars. It means that in addition the candidate has to say what
information about the red cars the user will have to give out once she finds
them.
4 marks
- Identify a complex problem.
- The type of problem identified must require:
- at least two different types of software to produce the solution
- the transfer of data, NOT by “cut and paste” between the two or more
packages.
- It is clear that the definition of the problem above requires, as an
absolute minimum, a database and a word processor. Also, this requirement
must be part of the problem and not commented on as one of the parts to be
developed within the solution. (i.e. the problem is complex, not the
solution)
- Describe the nature of the existing problems.
- This is much the same as for 3 marks but all aspects of the problem must
be considered.
- Describe the user’s requirements.
- Again this is much the same as for 3 marks but for all aspects of the
problem.
ANALYSIS - Use Methods of Collecting Information
This sub-section has a total of 4 marks. The marking points are hierarchical
but this time instead of adding statements every mark, words like ‘list’ are
replaced by words like ‘describe’.
1 mark
- Collect information from potential users.
- Candidates have to provide evidence that they have used at least one
method of collecting information from potential users of a system. This
could take the form of interviews with owners of car showrooms or letters
sent to them. They must include the information they have collected such as
replies to letters, completed questionnaires and transcripts of interviews
and documents they have gathered which are currently used by the showroom.
2 marks
- Collect information from potential users and
describe the method used.
- Candidates now need to describe how they obtained their information.
They will describe the interview, letter or questionnaire and how it was
used to obtain information as well as describing what information they were
seeking.
3 marks
- Collect information from potential users,
describe the method used and suggest alternatives.
- Candidates must describe alternative methods of collecting information.
This will include the methods which they did not use.
4 marks
- Collect information from potential users, and
justify the method used, compared with alternatives.
- Candidates must explain the disadvantages and advantages of their own
and alternative methods. This will give them the basis for explaining why
their choice was the most suitable.
ANALYSIS - Identify the Inputs, Outputs and Processing Required
This sub-section also has a total of 4 marks. This time each marking point is
an extension of the one above, but again it is essential for candidates to get
each marking point before they move onto the next one. Within the Analysis
section, the candidate should document a number of specific tasks their system
will be expected to perform.
1 mark
- List the inputs, outputs and processing required.
- The inputs will be the type of queries that customers might make to the
salesman in the car showroom. For example, one might be ‘Have you any red
Fords?’
- A list of the outputs will then need to be made. These will be the
details the salesman needs to retrieve from the system in order to answer
the queries listed above.
- A list of the processing requirements of the current system will need to
be made. This will be a list of the methods used by the salesman to find the
information from the current system in response to the customer query.
2 marks
- Describe the inputs, outputs and processing
required.
- This is an extension of the 1-mark requirements in as much as some
detail is required. Candidates need to do this for all the possible
situations they can think of. Not just customer queries but the other
aspects to the problem as outlined in the introduction above.
3 marks
- Suggest a system specification for the solution.
- This will be a list of the hardware and software which the candidate
intends to use in order to solve the problem, accompanied by a commentary
indicating why certain items are suitable for the system being developed. At
this stage brand names do not need to be mentioned, just the types of
software they intend using for the different aspects of the solution.
4 marks
- Justify a system specification for the solution
compared with alternatives.
- Candidates must compare their proposed system with possible
alternatives, i.e. different hardware specifications and a possible choice
of integrated software or different named packages for each part of the
solution.
