Q

What are the 2 sequencing and scheduling tools?

A

1) Gantt Chart
2) Critical Path Analysis

17
Q

What is the critical path?

A

The shortest time to complete ALL activities

(Remember, the longest path is the shortest time in which you could get everything done)

18
Q

Why is a Gantt Chart useful?

A
  • Helps to predict the completion date
  • Helps to organise what staff are working on
  • Provides a plan to measure progress against (to see if you are behind or ahead of schedule)
19
Q

What are limitations of a Gantt Chart?

A
  • Can be complex to make and use if there are lots of activities
  • Unlike CPA, it doesn’t show which tasks depend on each other
20
Q

Why is a critical path analysis useful?

A
  • Shows which tasks can be done simultaneously, to allow you to complete all tasks in the shortest possible time
  • Provides a plan to measure progress against (to see if you are behind or ahead of schedule)
21
Q

What are limitations of a critical path analysis?

A
  • Unlike a Gantt chart, it doesn’t show the date on which tasks will be completed
  • Diagrams can become complicated for projects with many steps
22
Q

How does technology improve the transformation process?

A

While it has high up-front costs, it can help to:
- increase speed
- reduce waste
- reduce defects

23
Q

What is task design?

A

The steps to produce a product

24
Q

What are two benefits of task design?

A

1) Staff know how to produce the product efficiently
2) Managers know the skills needed so can allocate or recruit the appropriate staff for the task

25
What is process layout?
How equipment is organised in operations
26
Why is process layout important?
It can improve the efficiency of production
27
What are the 3 types of process layout?
1) Product layout 2) Process layout 3) Fixed position layout
28
What is the process layout called 'product layout', and what is it good for?
An assembly line, which is good for mass production
29
What is the process layout called 'process layout', and what is it good for?
Equipment is grouped by function (like a mechanic or a hospital), and is good for variety and customisation
30
What is the process layout called 'fixed position layout', and what is it good for?
The product stays still and equipment is brought to it when needed. Good for very big products, like a building site or a plane
31
What is monitoring?
Measuring key performance indicators, such as defect rates, costs and lead times (how long it takes to produce the product)
32
What is controlling?
Comparing actual vs planned results and taking corrective action
33
When we say 'monitoring, controlling and improvement', what is improvement?
Finding new ways to continue to improve operations further
