-division of labour:the allocation of labour into specific tasks intended to increase productivity -specialisation:where workers performs specific tasks
26
Advantages and disadvantages of division of labour
+increase productivity, output increase and unit cost decrease, improved profit margin -task may be boring and repetitive leading to errors or high labour turnover, automation replaces workers
27
What is productivity and how to calculate it

32
What is economies of scale
When demand/ output increases unit costs decrease
33
What is diseconomies of scale and why does this happen
When output increases so unit costs increase, why; -large scale production can be difficult to manage so storage costs will increase -productivity may fall due to dw motivation of increased output
34

Actual level of output/ maximum possible output X100
38
How to increase capacity utilisation and what are the constraints
Increase: -increase demand for existing products -price cutting -differentiate the product Constraints: -competition -market dominance -stage in the product life cycle -seasonality -causes high demand and may not be able to produce as much

55
Advantages and disadvantages of time based management
+quicker response times to meet changing market and customer needs, faster new product development, reduction in waste -employees feel pressured to complete projects on time, workers may not what to multitask, employees may resist change

Quality control means how a company measures product quality and improves it if need be. Quality control can be done in many ways, from testing products, reviewing manufacturing processes, and creating benchmarks. Checks are done at the end of the process.
72
Advantages and disadvantages of quality control
+prevent faulty products reaching customer, less time wasted, can find wider problems and solve them sooner, keeps good reputation. - if defect levels are very high, the company's profitability will suffer, individuals are necessarily influenced to take responsibility for their work.

78
What is CPA
-critical path analysis is a project-management technique that lays out all of the activities needed to complete a task, the time it will take to complete each activity and the relationships between the activities. -the sequence of project activities which add up to the longest overall duration
79
What does CPA calculate
-the longest path of activities to the end of the project -earliest and latest each activity can start and finish
80
What does the 3 section in the circle mean and what does EST and LFT stand for in CPA
-the left hand of the circle is the activity number in order. -EST: the top section of the circle which shows the earliest start time that a activity can commence based on completion of the previous activity. -LFT: bottom right section shows the latest finish time by which the previous activity must be completed.
81
What does total float, free float mean
-total float: amount of time that an activity can be delayed from its start date without delaying the finish time of the project. -free float: the amount of time the network can be delayed without causing delay to the next task
82
Calculations of EST, LFT, total float, free float.
EST: EST plus the time a task takes to complete LST: latest finishing time total (end number) mines the time the previous activity took (start from back to front) Total float: LFT-EST Free float: EST-LFT
83
Advantages and disadvantages of CPA
+reduces the risk and cost of complex projects, help stop which activity have slack time, useful overview for estimated time of project to be finished. -based on estimations so not reliable, doesn’t take into account external issues, resources may not be as flexible as management thought
84
What is a Gantt chart
A geographical representation of the order and duration of tasks within a project. It is a simple and useful tool for planning and monitoring the progress of a project.
85
Gantt chart advantages and disadvantages
+visual representation, easy to monitor, shows time and resource allocation -doesn’t show critical activities, can’t see EST and LFT, can’t calculate floats
86
What is PERT
The Program Evaluation Review Technique. Using the technique helps project planners identify start and end dates, as well as interim required tasks and timelines. -optimistic time (shortest) -pessimistic time (longest)
87
PEST calculations
Estimated duration of a project= optimistic time+ (4 x likely time) + pessimistic time / 6
