AS Unit 3    Coursework:

The Use of Generic Application Software for Task Solution

Specification

For the AS Unit 3, candidates will be required to undertake a project.

For this project the candidates will be expected to tackle a task related problem which will have a limited scope and be self contained. The solution is very likely to be based on the facilities of one piece of generic software but candidates are encouraged to use other software tools and objects as appropriate to complete the solution.
It is not within the spirit of this syllabus for candidates to use a stand-alone general purpose programming language. The problems could be set by the candidates’ teacher, who will then
act as the end-user, or by a real end-user. To help with authentication of candidates’ work, if the same problem is given to more than one candidate, it must be tailored individually by each candidate to allow for differentiated outcomes. To gain high marks, candidates will be expected to provide a
detailed solution specification. This solution should reflect the use of advanced generic and package specific skills. It is desirable that a project log be included so that candidates can show their approach
to the solution and development of the solution, with regard to the use of alternative techniques and tools.

12.1 Process Skills:                                                                                                               

  • Develop generic and package-specific skills and apply as appropriate.


12.2 Specification:                                                                                                                

  • Produce a requirements specification for the identified problem, to match end-user needs.
  • State the input, processing and output needs to match the requirements specification.
  • Select and apply appropriate design tools and techniques.
  • Determine the test strategy and test plan for the solution.                                                                 
  • The test plan should include suggested test data.                                                                          

12.3 Implementation:                                                                                                              

  • Make full and effective use of the chosen hardware and software facilities to develop and implement a design as an information technology solution.
  • Use appropriate data capture and validation procedures, data organisation methods, output contents and formats, operational procedures and user interface(s) when developing the IT solution.
  • Relate the solution to the capabilities of the available hardware, software and human resources and to the time constraints.

12.4 Testing:                                                                                                                                

  • Test the implementation to ensure full compliance with the requirements specification.
  • Follow the test plan in a systematic manner using typical, erroneous and extreme (boundary) data.
  • Annotate each test output, cross-referencing to the testing plan.

12.5 Evaluation:                                                                                                                        

  • Assess the effectiveness of the solution in relation to the original requirements specification.

12.6 User Guide:                                                                                                                    

  • Provide appropriate user documentation.

Assessment Criteria:

Introduction:
Assessment of project work It is necessary to provide a structure for the assessment of project work so that all teachers are, in general, following a common procedure. Such a procedure will assist with the standardisation of assessment from centre to centre. Each project is, therefore, to be assessed in accordance with the criteria set out below. In assessing candidates, centres must ensure that comparable standards are observed between different teaching groups. Each centre must produce a single order of merit for the centre as a whole.

Criteria for the Assessment of Unit 3:
The following categories are to be used in the assessment of the project. The criteria for marking these categories are listed below.


The project is marked out of a total of 60.

  • Specification 13 marks
  • Implementation 20 marks
  • Testing 12 marks
  • Evaluation 6 marks
  • User Documentation 9 marks
  • Total 60 marks.

 

Specification (13 marks):

  • 11-13      A detailed requirements specification has been produced for the identified problem, which matches the needs of the stated end-user(s).
    The input, processing and output needs, which match the requirements specification, are clearly stated.
    Effective designs have been completed which would enable an independent third party to implement the solution.
    An appropriate test strategy has been determined. An effective test and full testing plan has been devised. The testing plan includes the test data, expected outcomes and directly relates to the requirements specification.
  • 8-10      A detailed requirements specification has been produced for the identified problem, which matches the needs of the stated end-user(s).
    The input, processing and output needs, which match the requirements specification, are stated.
    Designs have been completed but lack detail, thereby preventing an independent third party implementation of the solution, or are inefficient in relation to the problem stated.
    A test strategy has been determined and testing plans have been devised which are limited in scope or do not relate to the requirements specification stated.
  • 4-7      A requirements specification has been produced for the identified problem, but does not fully match the needs of the stated end-user(s), or lacks detail and clarity.
    The input, processing and output needs are stated, but do not fully match the requirements’ specification or are unclear.
    Design work has been attempted but is incomplete and does not reflect an efficient solution to the problem stated.
    A test strategy has been determined but is either incomplete or does not relate to the requirements specification stated. The testing plan is either vague or has been omitted.
  • 1-3      The requirements specification is vague or has been omitted.
    The input, processing and output needs are only vaguely considered or have been omited.
    There is little or no effort on design.
    The test strategy and testing plan are vague or missing.
