Definitions 3.2 Flashcards
Seasonal variation
change in the value of a variable that is related to seasons
Criterion level
a yardstick set by directors to enable managers to judge whether investment ideas are worth pursuing (e.g. ARR must be 15+% or payback must be a max of 12 months)
Cumulative cash
the buildup of cash over several time periods
Discounting
applying a discount factor to a money sum to take into account the opportunity cost of money over time
Present values
the discounting of future cash flows to make them comparable with today’s cash. this takes into account the opportunity cost of waiting for the cash to arrive
Short-termism
making decisions on the basis of the immediate future and therefore ignoring the long-term future of the company
Tactical decisions
those that are day-to-day events and therefore do not require a lengthy decision making process
Actual values
although known as actual values or payoffs, these are the forecasts of the net cash flow which result from following a sequence of decisions and chance events through a decision tree. They should always be at the ends of the branches of the tree
Expected values
these are the forecast actual values adjusted by the probability of their occurrence. Although called ‘expected’, they are not the actual cash flows which result. Expected equals actual times probability
Net gains (or losses)
subtracting the initial outlay from the expected value to find out whether or not a decision is likely to produce a surplus
Node
a point in a decision tree where chance takes over. It is denoted by a circle, and at that point it should be possible to calculate the expected value of this pathway
Probability
the likelihood of something occurring. Expressed as a numerical value, can be a percentage, a fraction or a decimal. Probability of something certain is 100% or 1. Something impossible is 0. Range from 1 to 0
Critical path
the activities that put be completed on time for the project to finish on time. They have no float times at all
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
Network
diagram showing all the activities needed to complete a project, the order in which they put be completed and the critical path
