  7. Decisions, Decisions, Decisions • People make decisions all the time. • Which job offer to take? • Which market to expand into? • Decisions include a number of criteria. • Some decisions include a small number of criteria • Other decision include a large number of criteria some of which are practically impossible to quantify. • When making decisions, one usually has alternatives. It is difficult to select the “best” alternative. Management Information Systems for the Information AgeSecond Canadian Edition

  8. Decisions, Decisions, Decisions Decision making is one of the most significant and important activities in business. This is why organizations spend tremendous amount of time and money to the decision making process. Management Information Systems for the Information AgeSecond Canadian Edition

  9. Decisions, Decisions, DecisionsHow You Make a Decision Figure 4.2Four phases of decision makingpage 135 Management Information Systems for the Information AgeSecond Canadian Edition

  10. Decisions, Decisions, DecisionsHow You Make A Decision Step 1: Intelligence Find or recognize aproblem, need, or opportunity. • This is the diagnostic phase of the decision making • Involves the detection and interpretation of signs • Consistent customer request for new feature or product • Threat of new competition • Declining sales • Rising costs • Offer from a company to handle your distribution needs Management Information Systems for the Information AgeSecond Canadian Edition

  11. Decisions, Decisions, DecisionsHow You Make A Decision Step 2: Design Consider ways to solve the problem, fill the need, or take advantage of an opportunity. This is the phase where you would study all possible solutions and develop those that are most interesting and feasible. Management Information Systems for the Information AgeSecond Canadian Edition

  12. Decisions, Decisions, DecisionsHow You Make A Decision Step 3: Choice Examine and weigh the merits of each solution, estimate the consequences of each, and choose the best one. • This is the prescriptive phase of the decision making. • In this stage a course of action is prescribed and this course of action could simply be to do nothing. • Selection of best solution requires selection criteria such as: • Cost • Ease of implementation • Staffing requirements • Timing Management Information Systems for the Information AgeSecond Canadian Edition

  13. Decisions, Decisions, DecisionsHow You Make A Decision Step 4: Implementation Carry out the chosen solution, monitor the results, and make adjustments as necessary. The implementation of final solution is seldom enough and will practically always need fine-tuning. Management Information Systems for the Information AgeSecond Canadian Edition

  14. Decisions, Decisions, DecisionsTypes of Decisions You Face Figure 4.3Viewing Structured Versus Nonstructured Decision Making as a Continuumpage 136 Management Information Systems for the Information AgeSecond Canadian Edition

  15. Decisions, Decisions, DecisionsTypes of Decisions You Face • If you want to decide which cheese to by then the criteria would be based on: • Expiry date • Price • If you have to decide which job offer is better to accept, then the criteria for your decision would be based on: • Salary • Intrinsic motivation • Location • Company • Position • Benefits • Many other criteria Management Information Systems for the Information AgeSecond Canadian Edition

  16. Decisions, Decisions, DecisionsTypes of Decisions You Face • In the cheese case, the criteria are pretty straight forward, hence the decision making is rather STRUCTURED. • In the case of the job offer, the criteria are many and most are not straight forward and are difficult to quantify, hence UN-STRUCTURED. Management Information Systems for the Information AgeSecond Canadian Edition

  17. Decisions, Decisions, DecisionsTypes of Decisions You Face Structured decision Processes information in a specified way so that you will always get the right answer. • Does not involve any “feel” into the process • Does not require intuition • These types of decision can be easily programmed • Fixed set of input • Same processing • Produce correct result Management Information Systems for the Information AgeSecond Canadian Edition

  18. Decisions, Decisions, DecisionsTypes of Decisions You Face Non-structured decision One for which there may be several “right” answers and there is no precise way to get a right answer. • No rules or criteria exist that guarantee you a good solution. • Examples • To introduce a new product line or not • To employ a new marketing campaign • To change the corporate image Management Information Systems for the Information AgeSecond Canadian Edition

  19. Decisions, Decisions, DecisionsTypes of Decisions You Face Recurring decision One that happens repeatedly, and often periodically. • Usually use the same set of rules each time. Management Information Systems for the Information AgeSecond Canadian Edition

  20. Decisions, Decisions, DecisionsTypes of Decisions You Face Nonrecurring decision One that you make infrequently. • Or ad-hoc decision • May have different criteria for determining the best solution each time • Example • Company merger Management Information Systems for the Information AgeSecond Canadian Edition

  21. Decision Support Systems Management Information Systems for the Information AgeSecond Canadian Edition

  22. Decision Support Systems Highly flexible and interactive IT system that is designed to support decision making when the problem is notstructured. Management Information Systems for the Information AgeSecond Canadian Edition

  23. Decision Support Systems • A DSS is an alliance between • you, • the decision maker and • specialized support provided by IT Management Information Systems for the Information AgeSecond Canadian Edition

  24. Decision Support Systems • A DSS brings • Speed • Vast amounts of information • Sophisticated processing capabilities To Help YOU Create information USEFUL to make a DECISION Management Information Systems for the Information AgeSecond Canadian Edition

  25. Decision Support Systems • You bring the know-how in the form of • Experience • Intuition • Judgment • Knowledge of relevant factors • You must know the right kind of questions to ask and how to process the information so you may get useful answers from the IT.
