Flashcards in Decision-Making Techniques 3.3 Deck (71):

1

## what are the four main methods used to provide a quantitative sales forecast?

###
1. moving averages

2. extrapolation

3. correlation

4. test market

2

## what are the two main circumstances where moving averages are helpful?

###
1. where there are strong seasonal influences on sales

2. where sales are erratic for no obvious reason

3

## Describe how to find moving averages:

###
1. calculate the moving total (usually a three month total e.g. jan, feb and march, and then feb, march and April)

2. The second column has the total of the three months (centred average) is divided by three to make the centred three month average, and centred back to February

4

## what is forecasting using extrapolation?

### It is the simplest was to predict the future - just using previous values, so on a graph you continue the line that was previously there. You must still ensure that the graph makes sense for it to continue up, for example ice creams in bad weather are likely to not go up.

5

## what is the table which uses correlation called?

### a scatter graph

6

## what are 6 limitations of quantitative sales forecasting techniques?

###
1. new entrants into the market

2. a sudden wave of viral, social media support or criticism of the product or celebrity promoting the products

3. population changes

4. changes in weather conditions

5. legal changes

6. internal factors - changes in sales force, changes in the amount of spending on promotion our way the product is being spent

7

## what is the definition of a sales forecast?

### a method of predicting future sales using statistical methods

8

## what is the definition of seasonal variation?

### change in the value of a variable that is related to the seasons

9

## what is the definition of a trend?

### the general path a series of values follows over time, disregarding variations or random fluctuations

10

## what are the three types of investment appraisal?

###
1. payback period

2. average rate of return

3. net present value (NPV)

11

## what are 5 reasons that a business should invest?

###
1. demand for business/ product

2. lower levels of risk

3. amount of rewards

4. reputation improvement

5. enough finance to fund the investment

12

## what are 4 advantages of payback period (IA method):

###
1. useful to decide between two options as its straightforward to compare

2. simple and easy to calculate and easy to understand the results

3. focuses on cash flows

4. good for future planning as it gives you a timeline for what could happen

13

## what are 4 disadvantages of payback period (IA method):

###
1. doesn't take into consideration other unexpected events

2. it will only be a forecast/ prediction

3. it doesn't look at the long term after the payback has been reached

4. ignores qualitative aspects of a decision (opinion/ if anything changes)

14

## what is the definition of payback?

### the time it takes for a project to repay its initial investment

15

## what is the average rate of return?

### The percentage return on the investment made

16

## what is the formula for the average rate of return?

### (average annual profit/ initial investment) x100

17

## what is the formula for average annual profit?

### profit for the period/ years

18

## do you want the average annual profit to be as high as possible or as low as possible?

### as high as possible

19

## When working out the average rate of return, and you are given the net cash flow, not the profit, what do you do?

### times the net cash flow by the years and minus the initial investment

20

## what is the definition of net present value/ discounted cash flow?

### the value in the present of a sum of money, in contrast to some future value it will have when it has been invested at compound interest

21

## what is the other name for net present value?

### discounted cash flow

22

## what is net present value?

### the difference between the present value of cash inflows and the value of cash outflows

23

## what is investment appraisal?

### its the process of analysing whether investment projects are worthwhile

24

## what happens if a NPV value is positive/ negative?

###
- NPV is positive then the project can be invested in

- NPV is negative then the project will be avoided/ rejected

25

## what is the calculation for a payback period?

### sum invested/ net cash per time period

26

## what is the interpretation of payback period?

### its the length of time the money is at risk. Every business should want as short a payback period as possible

27

## what are the three steps in calculating ARR?

###
1. calculate the total profit over the lifetime of the investment ( total net cash flows minus the investment outlay)

2. divide by the number of years of the investment project to give the average annual profit

3. apply the formula

28

## to discount a future cash flow, what is it necessary to know? (NPV)

###
1. how many years into the future we are looking, since the greater the length of time involved, the smaller the present or discounted value of money will be

2. what the prevailing rate of interest is likely to be

29

## what are three advantages of ARR?

###
1. Uses all the cash flows over the projects life

2. focuses on profitability

3. easy to compare percentage returns on different investments to help make a decision

30

## what are two disadvantages of ARR?

###
1. ignore the timings of the cash flows

2. ignores the opportunity cost of the money invested

31

## what are three advantages of NPV?

###
1. takes the opportunity cost of money into account

2. a single measure that takes the amount and the timing of cash flows into account

3. can consider different scenarios

32

## what are three disadvantages to NPV?

###
1. complex to calculate and communicate

2. the meaning of the result is often misunderstood

3. only comparable between projects if the initial investment is the same

33

## when forecasting cash flows 3/4 years in the future, what could go wrong? (4)

###
1. costs could rise unexpectedly, perhaps because of a fall in the value of a pound

2. a new competitor might push prices down undermining forecast cash inflows

3. consumer tastes might move away from your product

4. a cyclical downturn may turn into a full blown recession.

34

## what are 3 other factors affecting investment decisions?

###
1. non financial factors in investment appraisal

2. investment criteria

3. risk and uncertainty

35

## what are 4 other reasons why investment projects may be rejected?

###
1. corporate objectives

2. company finances

3. confidence in the data

4. social responsibilities

36

## what is the definition of criterion level?

### a yardstick set by directors to enable managers to judge whether investment ideas are worth pursuing

37

## what is the definition of cumulative cash?

### the build up of cash overall several time periods

38

## what is the definition of discounting?

### applying a discount factor to a money sum to take into account the opportunity cost of money over time

39

## what is the definition of present values?

### the discounting of future future cash flows to make them comparable with todays cash. This takes into account the opportunity cost of waiting for the cash to arrive

40

## what is the definition of short-termism?

### making decisions on the basis of the immediate future and therefore ignoring the long term future of the business

41

## what is the definition of tactical decisions?

### those that are day to day events and therefore do not require a lengthy decision making process

42

## what is the step-by-step approach to decision tree analysis? (3 steps)

###
1. the tree is a diagram setting out the key features of a decision making problems

2. the decision problem is set out from left to right

3. the branches consist of:

- a decision to be made, shown by a square

- chance of events or alternatives beyond the decision makers control, shown by a circle

43

## with probability, what do the numbers 0 and 1 represent?

###
0 - definitely will not occur

1 - definitely will occur

44

## what does the circle represent on a decision tree?

### chance of events beyond the decision makers control (E.G. success/ failure)

45

## what does the square represent on a decision tree?

### a decision to be made

46

## what are four advantages of using decision trees?

###
1. it allows for uncertainty

2. demand that managers consider all the possible alternative outcomes

3. set out the problems clearly and encourage a logical approach

4. encourage a quantitive approach and force assessments of the chances and implications of success and failure

47

## what are three disadvantages of using decision trees?

###
1. may be difficult to get meaningful data, especially for estimated probabilities of success or failure

2. less useful in the case of completely new problems or one-off strategic problems

3. can be relatively easy for a manager seeking to prove a case to manipulate any data

48

## what is the definition of a node?

### a point in a decision tree where chance takes over. It is denoted by a circle and at this point it should be possible to calculate the expected value of this pathway

49

## what is the definition of an actual value?

### the forecasts of the net cash flow which result from following a sequence of decisions and chance events through a decision tree

50

## what is the definition of an expected value?

### these are the forecast actual values adjusted by the probability of their occurrence

51

## what is the definition of a net gain (or loss)?

### subtracting the initial outlay from the expected value to find out whether or not a decision is likely to produce a surplus

52

## what is the definition of probability?

### the likelihood of something occurring. This can be expressed as a numerical value which can be a percentage, a fraction, or a decimal. the probabilities range from 0 to 1.

53

## what is critical path analysis?

### a technique used to consider the most efficient way to complete an activity.

54

## what are the rules/ oder of completing a CPA? (8)

###
1. work from left to right

2. complete EST first (top right)

3. when two activities go into one node select the highest value

4. at the end you duplicate the number

5. work from right to left

6. complete all LFT

7. when two activities go into a node. select the lower value

8. Reach the final node, you identify the critical path (path where the numbers are the same)

55

## what is another name for critical path analysis?

### a network diagram

56

## why do businesses need to plan complex projects? (5)

###
1. mitigate the risk

2. ensure the right path is taken - by identifying the most efficient method

3. useful to secure finance

4. time planning - to prioritise critical tasks

5. to find the float time to find the flexibility

57

## what is the calculation for float time for a certain activity?

### LFT-duration-EST

58

## what is LFT?

### latest finish time

59

## what is EST?

### earliest start time

60

## what are four positives of CPA?

###
1. find out the float time and the overall time frame

2. identify where there is flexibility

3. reduce risk and cost of complex projects

4. provides managers with overview of project

61

## what are three negatives of CPA?

###
1. Numbers are all based on predictions

2. CPA doesn't guarantee success

3. Resources may not be as flexible as managers hope with the network float

62

## what does the network analysis show?

###
1. the order in which each task must be undertaken

2. how long each stage should take

3. the earliest date at which the later stages can start

63

## what is the critical path?

### the critical path is the route which allows the project to be completed in the shortest amount of time

64

## where is the float time found on the CPA diagram?

### in the non critical activities

65

## what are three benefits of using network/ critical path analysis?

###
1. requires careful planning of the order in which events need to occur, and the length of time each one should take, this should improve smooth operation

2. the resources needed for each activity can be ordered or hired no earlier than their EST, so the working capital is minimised

3. can identify events which can take place simultaneously, it shortens the length of time taken to complete a project

66

## what are two limitations of using network/ critical path analysis?

###
1. a complex project entails so many activities that a drawing becomes unmanageable.

2. drawing a diagram doesn't ensure the effective management of a project, it provides a plan but can only be as successful as the staff's commitment to it

67

## what is the definition of a critical path?

### the activities that must be completed on time for the project to finish on time. they have no float time at all

68

## what is the definition of float time?

### any spare time that arises between the completion of an activity and the starting time of the next

69

## what is the definition of management by exception?

### the principle that because managers cannot supervise every activity within the organisation they should focus their energies on the most important issues

70

## what is the definition of network?

### a diagram showing all the activities needed to complete a project, the order which they must be completed and the critical path
