The following estimatesare made: Since the expected value shows the long run average outcome of adecision which is repeated time and time again, it is a useful decisionrule for a risk neutral decision maker. (b)   Choose the best option at each decision point and recommend a course of action to management. Decision trees should be used where a problem involves a series ofdecisions being made and several outcomes arise during thedecision-making process. Probability distributions may be difficult to formulate. Factors to consider when using desk research. A circle is used to represent a chance point. Future events that may occur present variables that may affect the success of the project. For indifference, the contribution from outsourcing needs to fallto $5 per unit. (b) We will calculate the Expected Value of profits if we employ the geologist. If the minimax regret rule is applied to decide how many saladsshould be made each day, we need to calculate the 'regrets'. Now let's look at the different values of profit or losses depending on how many salads are supplied and sold. Such samples are morelikely to be representative, making predictions more reliable. Risk is thus closer to probability where you know what the chances of an outcome are. whether to advertise the programme, or not advertise.). That does not, however, mean that they are the same thing. The use of research techniques to reduce uncertainty. The EV gives no indication of the dispersion of possible outcomes about the EV, i.e. A number of research techniques are available: Focus groups are a common market research tool involving smallgroups (typically eight to ten people) selected from the broaderpopulation. The maximum possible change is often expressed as a percentage.This formula only works for total cash flows. The profit expected, before deducting the cost of advertising, at different levels of student numbers are as follows: Demonstrate, using a decision tree, whether the programme should be advertised. The digital revolution, climate change, stakeholder expectations, and geopolitical risk will play major roles. Risk can be controlled if proper measures are taken to control it. Objectives are what matters! It can often eliminate the need for extensive field work. Conversely, many companies, especially blue-chips and public services, can often be seen to produce reams of data for no apparent reason, or because 'we always have done'. Risk and uncertainty are really two ends of a single spectrum. through the use of cameras withinsupermarkets to examine how long customers spend on reading thenutritional information on food packaging. 3. ‘Regret' in this context is defined as the opportunity loss through havingmade the wrong decision. win, lose, draw, 2-1,3-0, etc), Quoted odds can help estimate probabilities, The outcomes of the simulation could be used to assess impact on cash flow, whether bets should be laid off with other betting agents to reduces risk, etc. Introduction to Risk: 2008 Financial Crisis; 3. It assumes that changes to variables can be made independently, e.g. Best estimates for variables are made and a decision arrived at. Word association testing – on being given a word by the interviewer, the first word that comes into the mind of the person being tested is noted. The maintypes of measurement are: Random sampling– where each person in the targetpopulation has an equal chance of being selected. Some decision makers do not like uncertainty at all. The ISO 31000 standard on risk management. 2. Here, the highest maximum possible pay-off is $140. Profits are therefore maximised at 50 salads and amount to $90. Label the tree and relevant cash inflows/outflows and probabilities associated with outcomes. Some common symbols can be used: a square is used to represent a decision point (i.e. If there is no oil, the probability that she willsay prospects are poor is 85%. An expected value is a weighted average of all possible outcomes.It calculates the average return that will be made if a decision isrepeated again and again. A risk is the effect of uncertainty on certain objectives. All businesses face risk. The first one is risk is defined as the situation of winning or losing something worthy while uncertainty is a condition where there is no knowledge about the future events. There is only a 10%chance that you will strike oil if you drill, but the profit is$200,000. Market research is an important means of assessing and reducinguncertainty. The branches coming away from a circle with have probabilities attached to them. where a choice between different courses of action must be taken. Since this is less than the cost of buying the information($7,000), we should not employ the geologist. If there is oil, the probability that she will say there aregood prospects is 95%. How much is this new system worth to Mr Ramsbottom? Group interviewing – where between six and ten people are asked to consider the relevant subject (object) under trained supervision. The Spanish flu (1918–1920), Asian flu (1957–1958), Hong Kong flu (1968–1969), and Swine flu (2009-2010) are among the best known. Treatment of risk and uncertainty vary in international management literature based on their interpretation of the terms “risk and uncertainty” and the categorization of risk. For example, about the likely responses of customers to newproducts, new advertising campaigns and price changes. Using maximin, a pessimist would consider the poorest possible outcome for each product and would ensure that the maximum pay-off is achieved if the worst result were to happen. MOst technological hazards are characterized by substantial uncertainty. Market research findings, for example, are likely to bereasonably accurate - but they can still be wrong. If there is oil, the probability that she will say there aregood prospects is 95%. Panelling– where the sample is kept for subsequent investigations, so trends are easier to spot. If the business is willing to take on risk, they may prefer project B since it has the higher average return. Risk perception. We should therefore decide to supply 70 salads a day. The value of information (either perfect or imperfect) may be calculated as follows: Expected Profit (Outcome) WITH the information LESS Expected Profit (Outcome) WITHOUT the information, Test your understanding 4 - Geoffrey Ramsbottom. There is a 40% chance that economic conditions will be good. Then we … A great deal of information is freely available in this area from sources such as government ministries, the nationalised industries, universities and organisations such as the OECD. This sort of information can also be collected in retail environments at the point of sale, for example, through the use of loyalty cards. Ithas a number of potential films that it is considering producing, one ofwhich is the subject of a management meeting next week. If we employ the geologist, the probabilities of her possibleassessments can be tabulated as follows (assume 1,000 drills in total): A decision tree can be drawn to calculate the expected value of profits if a geologist is employed: EV(A) = (41.30% x $200,000) - $10,000 drilling costs = $72,600.The decision at 'C' should be to drill, as this generates higherbenefits than not drilling. If 40 salads will be required on 25 days of a 250-day year, the probability that demand = 40 salads is : Likewise, P(Demand of 50) = 0 .20; P(Demand of 60 = 0.4) and P(Demand of 70 = 0.30). At the first (and only) decision point in our tree, we shouldchoose the option to advertise as EV ('D') is $82,000 and EV ('C) is$75,000. Imperfect information The forecast is usually correct, but can be incorrect. If we decide to supply 40 salads, the minimum pay-off is $80. It obtains existing data by studying published and other available sources of information. The financial outcomes and probabilities are shown separately, andthe decision tree is ‘rolled back' by calculating expected values andmakingdecisions. However, it is quicker and cheaper than field research. Observation– e.g. The random numbers generated give 5 possibleoutcomes in our example: A business is choosing between two projects, project A and projectB. Risk management is important in a business. Risk management is the process of identifying, assessing and controlling threats to an organization's capital and earnings. Depth interviewing – undertaken at length by a trained person who is able to appreciate conscious and unconscious associations and motivations and their significance. It helps to break surprise down to three types: risk, uncertainty and ignorance. Here C would be chosen with a maximum possible gain of 100. Tangible and Intangible Risks; 8. Diversifiable and Nondiversifiable Risks; 7. Project B has a higher average profit but is also more risky (more variability of possible profits). The information is collected from secondary sources. EV(B) = (0.65% x $200,000) - $10,000 drilling costs = -$8,700. Accountants (IESBA), published by the International Federation of Accountants (IFAC) in December 2012 and is used with permission of IFAC. Exploring Risk - Lesson Summary Quota sampling– where samples are designed to be representative with respect to pre-selected criteria. Such information will be both commercial and technical, for example, the level of sales of competitors' products recorded by the Business Monitor or Census of Production; the product range offered by existing or potential competitors; the number of outlets forming the distribution network for a company's products; the structure of that network by size, location and relation to the end user; and the best overseas markets for a company. The incentive is to significantly reduce the cost of projects by curbing unnecessary spend, especially In summary it suggest when faced with missing or imperfect information about an event, probability, or outcome, we are uncertain. Developing themes in Management Accounting. This helps to model what is essentially a one-off decision usingmany possible repetitions. For example, it may be that the estimated selling price can fall by 5% before the original decision to accept a project is reversed. Takes uncertainty into account by considering the probability of each possible outcome and using this information to calculate an expected value. They are not. Basically, when unsure, there is risk of the results being different than our expectations. The words Risk and Uncertainty are often used interchangeably, and for good reason: The one cannot exist without the other. Decision trees force the decision maker toconsider the logical sequence of events. View our, « A video of the great grandchild of the product of the first HALT, Probability and Statistics for Reliability. Risk is the variability of possible returns. material prices will change independently of other variables. If the project is chosen, those areas can be carefully monitored. Copyright 2020. This meanswe need to find the biggest pay-off for each demand row, then subtractall other numbers in this row from the largest number. Therefore, our analysis must extend to deal with imperfect information. However,the technique may be unfeasible in practice. It can include all random events that mightaffect the success or failure of a proposed project - for example,changes in material prices, labour rates, market size, selling price,investment costs or inflation. Answer - University advertising decision tree. Risk Exposure; 6. It provides information on the basis of which decisions can be made but it does not point to the correct decision directly. Internal company data is perhaps the most neglected source of marketing information. Test your understanding 3 - Applying maximin. It cannot be used for individual units, selling prices, variable cost per unit, etc. 4. Following up from the pay-off table example, Geoffrey Ramsbottom's table looks as follows: The manager who employs the maximax criterion is assuming thatwhatever action is taken, the best will happen; he/she is a risk-taker.How many salads will he decide to supply? These threats, or risks, could stem from a wide variety of sources, including financial uncertainty, legal liabilities, strategic management errors, accidents and … The time and costs involved in their construction can be more than is gained from the improved decisions. The paper argues that such methods can be used to enhance the risk management of projects. If conditions are poor it is expected that the programme will attract 40 students without advertising. The company knows that it is possible for them toeither find or not find oil but it does not know the probabilities ofeach of these outcomes. The EV may not correspond to any of the actual possible outcomes. You have the mineral rights to a piece ofland that you believe may have oil underground. Risk and Uncertainty Management Light and dark, joy and pain, yin and yang…everything good in this world must come with an opposite, and your business is no exception. Risks can be managed while uncertainty is uncontrollable. For example, a supermarket may use a focus group before a productlaunch decision is made in order to gather opinions on a new range ofpizzas. The probabilities used are usually very subjective. Helping you understand and navigate uncertainty and respond to risk in a crisis scenario The COVID-19 pandemic has forced middle market organizations into completely uncharted waters. This approach would be suitable for an optimist, or 'risk-seeking'investor, who seeks to achieve the best results if the best happens. In some cases we have a very accurate idea of the odds of an event happening, such as the McDonalds example above. The question often requires the candidate tocalculate the value of the forecast. Risk management deals with the issue of uncertainty. It provides an organisation with a picture of past and future trends in the environment and with an indication of the company's position in the economy as a whole. We will calculate the Expected Value of profits if we employ the geologist. Created at 5/24/2012 4:39 PM  by System Account, (GMT) Greenwich Mean Time : Dublin, Edinburgh, Lisbon, London, Last modified at 5/25/2012 12:54 PM  by System Account. In other words, it is obtained by multiplyingthe value of each possible outcome (x), by the probability of thatoutcome (p), and summing the results. In many questions the decision makers receive a forecast of afuture outcome (for example a market research group may predict theforthcoming demand for a product). The maximin rule involves selecting the alternative that maximisesthe minimum pay-off achievable. Risk metrics, or how to measure risk and safety. It is the process ofunderstanding and managing the risks that an organisation is inevitablysubject to. It costs $10,000 to drill. Itsstaff has asked you to help them decide how many salads it should supplyfor each day of the forthcoming year. Choose the best option at each decision point. This includes: The small sample size means that results may not be representative. Risk management is all about managing surprise. A manager is considering a make v buy decision based on the following estimates: You are required to assess the sensitivity of the decision to the external purchase price. Viral infections kill lots of people. A decision tree is a diagrammatic representation of amulti-decision problem, where all possible courses of action arerepresented, and every possible outcome of each course of action isshown. The Risk and Uncertainty Management Center provides knowledge, frameworks, tools and experiences that lead to better decision-making in situations involving a wide variety of risks confronting organizations. Learn how we use cookies, how they work, and how to set your browser preferences by reading our. On the other hand, uncertainty is beyond the control of the person or enterprise, as the f uture is uncertain. A particular salad is sold tothe canteen for $10 and costs $8 to prepare. The number of students starting the programme is dependent on economic conditions: If the programme is advertised and economic conditions are poor,there is a 65% chance that the advertising will stimulate further demandand student numbers will increase to 50. Economic intelligence can be defined as information relating to the economic environment within which a company operates. Possible outcomes are easy to identify (e.g. Beyond the profound health and economic uncertainty of our current moment, catastrophic events are expected to occur more frequently in the future. Which project should the business invest in? For example, what is the chance of the selling price falling by more than 5%? Perfect information is only rarely accessible.
