AO2 Application
Application [m≪] (max 2 marks) can be awarded for applying operations/operations strategy to CA between 2019 and 2024 CA's operations decisions, including:
- CA is Nala's first job after university, only experience before being made Operations Manager was as a cleaner for CA.
- Planning opening of the new city Z branch, including:
- The use of critical path analysis
- 13 weeks to plan and open the branch (assuming no delays)
- Float available on activities C, D, F, G and H
- Critical path = A, B, E and J
- No built-in time to respond to research results
- Lean production methods introduced by Nala in 2021, including:
- Kaizen (continuous improvement) introduced throughout city Z branch
- All cleaners are placed in a quality circle, including one manager and eight cleaners in each team
- A target to ethically recycle 90% of customers waste
- Just in time re-ordering of cleaning materials
- CA's new AI system introduced in 2022, including:
- Majority of customer services operatives made redundant
- Chatbot system to interact with customers
- Book appointments, answer customer queries and take complaints
- Poor customer/media reaction
- Comparison between the operations of the city Z branch and the city A branch of CA in 2023, including:
- City Z branch has lower revenue than city A
- City Z branch has sightly improved revenue between 2021 and 2023 ( 2% increase)
- City A branch has 10% improved revenue between 2021 and 2023
- City Z branch has improved revenue, same number of cleaners whereas city A branch has increased cleaners
- City Z branch has a loss of $0.1 m in 2023, compared to an increased profit for city A branch.
- City Z branch has increased direct costs, despite introduction of lean production methods
- Rate of inventory turnover has increased in city Z branch (suggesting improvement) but may not have added to cost savings.

AO3 Analysis
Analysis is likely to be based on how operations may have affected CA's decision making ( △1 and A2 and △3 ) between 2019 and 2024, including:
- Nala's inexperience - poor decision making - too much responsibility - may have been integral to the failure of city Z branch - particularly important since city A branch has increased profitability.
- Did the city Z branch open too quickly? - Is 13 weeks long enough to plan such a large investment? - poor implementation of decisions.
- Critical path analysis is a useful theoretical tool, but does it have enough practical value when Nala and the business are new to the city? - increased costs - reduced profit.
- Built-in float may suggest inefficiency - Was the rent paid for too long before opening? - increased costs - reduced profitability.
- Employee recruitment in city Z had float - increased costs - reduced profit.
- However, CPA may have led to a more efficient opening - reduced costs - increased profit.
- No float between advertising and bookings - efficient.
- CPA allowed Nala to focus on what areas are most important - increased efficiency.
- Kaizen may have allowed more creative ideas to come from every area of the business - lower costs - however also detracts from the primary task of the cleaners (and other employees) - increased costs.
- Likewise, quality circles may detract from cleaning - may theoretically (academically) increase value of workforce but could lead to wasted time not focused on primary tasks like cleaning - increased costs. Also there may be problems of bringing mainly part-time employees together for meeting - may incur additional costs for wages. Also, attendance and contributions might depend on whether workers are paid for attending or not - employees may feel resentful and become demotivated - deceased productivity.
- Ethical recycling of customer waste may provide a USP to CA in city Z - however only if customers value this in the market.
- Just in time ordering may decrease costs of holding inventory - however it may lead to wasted time without necessary supplies.
- Chatbot system may lead to reduced indirect costs (less customer service employees needed) - however seems to have irritated customers and may lead to losing established customers going to other firms.

AO4 Evaluation
Evaluation (N1 and N2 and N3 ) including:
Evaluation will largely depend on the points raised in the analysis.
- A judgement over the extent to which operational decisions between 2019 and 2024 led to the failure of CA's city Z branch.
- Discussion over the contribution of the separate and combined decisions on the eventual failure of the city Z branch,
- The extent to which the decisions alone led to the failure of the city Z branch.
- Other likely influences on the failure of the city Z branch, such as the state of the economy in city Z, human resource management of the cleaners and indirect staff, Nala's personality, unrealistic expectations of the board of directors of CA, marketing of CA, especially for the city Z branch, the financing given to help the city Z branch become successful etc.
- The extent to which the failure of the city Z branch could be attributed to the operational decisions alone.
- The extent to which CA itself was deemed successful (city A branch).

Indicative content
Responses may include:
AO1 Knowledge and understanding
Limited knowledge K will be demonstrated through knowledge of lean production or knowledge of impact on operational objectives.
Developed knowledge K+K will be demonstrated through knowledge of lean production and knowledge of impact on operational objectives.
- Definition of lean production: reducing all forms of waste.
- Lean production techniques:
- TQM
- Quality circles
- Cell production
- JIT
- Kaizen
- Simultaneous engineering.
- Need for capital investment such as ERP or flexible machinery.
- Knowledge of relevant ratios such as inventory turnover.
AO2 Application
Limited application, APP applies knowledge to CQ once.
Developed application, APP + APP applies knowledge to CQ twice.
- Inventory turnover of 3.08 means that inventory is currently kept for 119 days on average. Objective is to increase inventory turnover to 5 times.
- Need to hold bamboo material for production and finished shoes to meet fluctuations in demand.
- 5% of output is defective - in six months =6000 units. Objective is to cut this by 50%.
- CQ has only just taken over the factory. Objective to increase production to full capacity within eight months and reduce workforce size.
- The shoe manufacturer had been unprofitable when CQ took it over.
- Unions have agreed to changes in working practices.

AO3 Analysis
Limited analysis AN - candidate shows one link in the chain of analysis.
Developed analysis L2AN - candidate shows two or more links in the chain of analysis.
- By reducing all forms of waste CQ will be more efficient, and this will reduce unit cost of production AN making CQ more competitive. L2 AN
- Lean production includes TQM and quality circles. Giving workers responsibility for quality may increase motivation resulting in a reduction in defective output, AN improve quality and productivity, making CQ more competitive. L2 AN
- Lean production includes JIT manufacturing. Aim to hold zero inventory which will increase inventory turnover AN resulting in less inventory holding costs. L2 AN
- Training of employees will be required thus increasing costs of CQ AN but this could increase motivation of employees resulting in higher productivity. L2 AN
- Lean production aims to use less of everything and therefore may enable production to be maintained whilst reducing the size of the labour force AN and therefore reduce unit costs. L2 AN
- Lean production by building relationship with suppliers could eliminate the supply chain failures AN thus reducing the high levels of inventory previously needed. L2/AN
- Use of JIT may result in CQ running out of inventory and therefore lead to a loss of sales. AN
AO4 Evaluation
Limited evaluation EvAL - limited supported judgement and/or a weak attempt at evaluative comment.
Developed evaluation L2 EvaL - supported judgement and/or reasonable evaluative comment.
Developed evaluation in context L3 | Eval - supported judgement in context and/or reasonable evaluative comment in context.
- Elements that the evaluation/judgement might depend on:
- Effectiveness will depend on supplier relationships and reliability of receiving supplies when needed. Supply chain with bamboo coming from the US may make JIT production difficult to implement due to long lead times.
- Can CQ predict demand accurately? JIT risks lost customers if demand is underestimated.
- Is inventory turnover high or low compared to competitors?
- Was part of the problem that workers are unfamiliar with the production methods for the bamboo shoes after the takeover?
- Cost of the investment and current financial situation of CQ such as its high gearing.

Indicative content
Responses may include:
AO1 Knowledge and understanding
Limited knowledge K will be demonstrated through knowledge of critical path analysis (CPA) or benefits of CPA
Developed knowledge K+K+ will be demonstrated through knowledge of critical path analysis (CPA) and benefits/limitations of CPA
- Understanding of CPA - network diagram, critical path, floats, minimum duration.
- Benefits of CPA: knowing minimum project time, start times for activities, progress monitoring, 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, △APP applies knowledge to CP once.
Developed application, APP +APP applies knowledge to CP twice.
Max one APP for application for the first impact of technological change and max one APP for application for the second impact of technological change.
- Importance of continuous supply to retailers.
- Contractor produced CPA.
- Contract based on accuracy and reliability of CPA.

AO3 Analysis
Limited analysis AN - candidate shows one link in the chain of analysis.
Developed analysis L2|AN - candidate shows two or more links in the chain of analysis OR offers a two-sided analysis.
- Development of knowledge and application points about usefulness of CPA to CP.
- CPA is quantitative as it allocates timings to activities, so can help with planning and monitoring to ensure project does not over-run. AN
- Contractor may have produced CPA and contract terms in order to get the contract. This may mean contract takes longer AN, which will lead to delays and dissatisfied customers. L2 AN
- CPA enables CP to determine non-production time and prepare, by building up inventory, before work starts. This will enable sales to proceed as normal AN and avoid potential of unmet orders and decreased sales and profit. L2 AN
- Enables monitoring critical activities, such as E (delivery of components) and allows CP to take action if a delay is threatened to ensure project is completed on time AN, minimising production interruptions.
AO4 Evaluation
Limited evaluation EvAL - limited supported judgement and/or a weak attempt at evaluative comment.
Developed evaluation L2 EvaL - supported judgement and/or reasonable evaluative comment.
Developed evaluation in context L3 EvAL - supported judgement in context and/or reasonable evaluative comment in context.
- Either conclusion is valid, as long as it is justified.
- CP has contract provision that CPA for the external use paint production line is accurate and reliable so more likely that it is, as the contractor will not want to pay penalty fees.
- CP experienced in paint production, rather than production line installation, so not likely to know accuracy of CPA.
- An accurate CPA will be very important for enabling continuous supply of external paints, so customers are not disappointed.
- CPA only as good as data and the skills of the person who prepared it. Some question about its accuracy so CP wise not to rely solely on its results, especially as the price is low and the contractor produced it.
- Other information is also important, such as staff training. The CPA does not allow for this.
- Work progress has to match the CPA plan, so CP would be wise to maintain constant check on progress before and after work starts.
