5 AO1 Knowledge and understanding
Limited knowledge will be demonstrated through knowledge of CPA or knowledge of CPA as a management tool for
operations planning.
Developed knowledge + will be demonstrated through knowledge of CPA and knowledge of CPA as a management
tool for operations planning.
• Understanding of CPA – network diagram, critical path, floats, minimum duration.
• Benefits of CPA: knowing minimum project time, start times for activities, progress monitoring, managing resources,
reducing costs, assessing significance of delays and if necessary corrective actions.
• Limitations of CPA: analysis only as good as input data, planning costs, does not ensure effective management.
AO2 Application
Limited application, applies knowledge to HCC once.
Developed application, + applies knowledge to HCC twice.
• Operations Manager produced the CPA.
• Six-week minimum time.
• Reduces disruption to production during improvements to employee facilities.
• Use of CPA for other projects e.g. development and launch of the Wonder Stove, expansion to international market.
Wonder Stove launched on schedule
Target to export by January 2025
AO2 Analysis
Limited analysis – candidate shows one link in the chain of analysis.
Developed analysis – candidate shows two or more links in the chain of analysis.
• CPA will help manage resources efficiently to ensure that resources are available when needed which will therefore
reduce costs of HCC’s operational changes and therefore support achievement of HCC’s social objectives .
• Identifying critical tasks of investing in the new employee facilities will ensure that those tasks are completed on time
and therefore reduce disruption to production minimised which reduce the cost to HCC of the improvements .
• Important to use CPA so that customers can be kept informed of any potential impact on orders . Important to avoid
customer dissatisfaction as this could result in loss of sales .
• Entering international market requires careful planning to get product to market on time and ensure products are
available for customers to purchase thus increasing sales .
5 AO3 Evaluation
Limited evaluation – limited supported judgement and/or a weak attempt at evaluative comment.
Developed evaluation – supported judgement and/or reasonable evaluative comment.
Developed evaluation in context – supported judgement in context and/or reasonable evaluative comment in
context.
• A judgement about the usefulness of CPA for operations planning.
• Evaluation of the relative importance of different advantages/disadvantages of CPA as a tool for operations planning.
• Elements that the evaluation/judgement might depend on – accuracy of the data used in CPA, need for constant
monitoring of external events
• CPA only as good as data – is operations manager capable of completing accurate CPA for the factory development?
• Other information is also important e.g. CPA needs to be interpreted
• Work progress has to match the CPA plan.
• HCC would be wise to maintain constant check on progress before and after work starts.
Accept all valid responses.
Exemplar evaluation and levels
L1 Limited evaluation
Overall, CPA could help HCC plan projects more efficiently, but its usefulness depends on having accurate data and skilled
staff to interpret it.
Comment: Judgement made but with limited supporting comment.
L2 Developed evaluation
Overall CPA is useful, especially for large costly projects, to make sure the production remains on time and does not
increase unnecessary costs with delays. Any delays or unplanned activities can increase costs and reduce profit. However,
it depends on the accuracy of the CPA. If there are errors in the plan then ultimately it would still cost the business money,
despite having made one. Its usefulness depends on the quality of the data used.
Comment: EVAL is sufficiently developed, but could apply to any business as there is no context, so limit to L2.
5 L3 Developed evaluation in context.
Critical Path Analysis (CPA) is useful to HCC as it helps ensure that deadlines for the improvements to staff facilities are
met. By highlighting the essential sequence of activities, HCC can allocate resources and reduce delays to ensure future
orders of their cook bags are still fulfilled. In the long term, without CPA, HCC may fall behind their schedule and disappoint
customers leading to a fall in brand image. However, it will rely on the skill of the operations manager to effectively plan the
sequence of works.
Comment:
Well balanced conclusion in context of the case L3.
