THE NATURE OF DECISION MAKING DECISION MAKING The act of choosing one alternative from among a set of alternatives. DECISION-MAKING PROCESS Recognize and define the nature of a decision situation Identify appropriate alternatives Choose and justify the best alternative (Recommend) Evaluated on basis of feasibility, effectiveness, and consequences Implement the recommendation (Put it into practice) EFFECTIVE DECISIONS Effective decisions optimize some set of factors: e.g. maximize profits, sales, market share or satisfaction, or minimize costs, waste, turnover, or unhappiness.
PRECONDITIONS FOR DECISION MAKINGIS THERE A PROBLEM WE REALLY MUST ADDRESS? IS THERE A PERFORMANCE GAP? Assumes there are standards to judge Assumes there is monitoring and feedback IS THE DECISION MAKER AWARE OF THIS GAP? Consciousness of the gap Significance to the organization DOES THE DECISION MAKER HAVE THE RESOURCES TO ACT? Knowledge and ability to fix the problem Budgets, personnel, power IS THE DECISION MAKER MOTIVATED TO ACT ON THE GAP? Rewards and risks weighed Risk-averse or risk-seeker?
TYPES OF DECISIONS ROUTINE (Programmed) COMMON PROBLEMS WITH WELL-DEFINED SOLUTIONS : Rules, procedures, computer software packages There is an obvious “best” solution or alternative ADAPTIVE A COMBINATION OF MODERATELY UNUSUAL AND ONLY PARTIALLY-KNOWN PROBLEMS AND ALTERNATIVES Incremental changes or modifications of past decisions and practices Selecting from a set of known alternatives, but unsure of the outcomes INNOVATIVE (Non-Programmed) UNUSUAL OR AMBIGUOUS PROBLEMS WHICH REQUIRE UNIQUE OR CREATIVE ALTERNATIVE SOLUTIONS Emphasizes radical change, innovation, brainstorming Not sure what the alternatives are, not sure whether any will work
RATIONAL DECISION MAKING MODEL DEFINE AND DIAGNOSE THE PROBLEMS SEPARATE SYMPTOMS FROM CAUSES CLARIFY THE OBJECTIVES TO BE ACHIEVED IDENTIFY CRITERIA TO BE USED SEARCH FOR ALTERNATIVE SOLUTIONS WE MUST HAVE OPTIONS FOR EACH PROBLEM COMPARE AND EVALUATE ALTERNATIVES EXPECTED RESULTS, COSTS, POTENTIAL SIDE EFFECTS? RECOMMENDED SOLUTIONS JUSTIFY WHY THIS CHOICE…WHY NOT THE OTHERS? IMPLEMENTATION STEPS AND PROCEDURES TO FOLLOW TO ENSURE SUCCESS MONITORING AND CONTROL ARE THINGS GOING AS EXPECTED? IS FURTHER INTERVENTION NEEDED?
RATIONAL MODEL ASSUMPTIONS PROBLEM CLARITY The problem is clear and unambiguous. The decision maker is assumed to have complete information regarding the decision situation. KNOWN OPTIONS The decision maker can identify all the relevant criteria and can list all the viable alternatives. Furthermore, the decision maker is aware of all the possible consequences of each alternative. CLEAR PREFERENCES The criteria and alternatives can be ranked and weighted to reflect their importance. CONSTANT PREFERENCES The decision criteria are constant and the weights assigned are stable. NO TIME OR COST CONSTRAINTS The decision maker can obtain full information about criteria and alternatives because it is assumed there are no time or cost constraints. MAXIMUM PAYOFF The rational decision maker will choose the alternative that yields the highest perceived value.
BOUNDED RATIONALITYSIMON (57) BASED ON A LIMITED PERSPECTIVE SOME IMPORTANT CRITERIA ARE NOT IDENTIFIED NOT ALL ALTERNATIVES ARE CONSIDERED SEQUENTIAL EVALUATION OF ALTERNATIVES CONSIDER OPTIONS ONE AT A TIME MAY ONLY COMPARE AND CONTRAST TWO OPTIONS SATISFICING IS THE OPTION UNDER CONSIDERATION “OK” or “GOOD ENOUGH?” SELECTION OF THE FIRST TOLERABLE OPTION JUDGMENTAL HEURISTICS AND BIASES OVERCONFIDENCE – “I’m 70% sure”…more like 50/50 ANCHORS -- Get stuck on some initial info…$15-$50 mill…”Primacy Effect” CONFIRMATION – Bias that remembers only data that supports your predisposition AVAILABILITY– Information that is readily available and vivid, we don’t dig deeper ESCALATION OF COMMITMENT – More investment in a bad decision

THREE “RATIONAL”DECISION PROCESSESCOMPENSATORY, CONJUNCTIVE, DISJUNCTIVE COMPENSATORY PROCESS (CLASSICAL) ALL IMPORTANT CRITERIA ARE CLEARLY IDENTIFIED CRITERIA ARE WEIGHTED ACCORDING TO IMPORTANCE ALL ALTERNATIVES CAN BE MATHEMATICALLY MODELED EXPECTED VALUE IS CALCULATED FOR EACH OPTION THE “BEST” EXPECTED VALUE IS THE OPTIMAL CHOICE USE OF EXPECTED VALUES ALWAYS LEADS TO THE OPTIMAL SOLUTION VERY HIGH PERFORMANCE ON ONE CRITERION CAN OFFSET WEAKNESSES IN ANOTHER ARE YOU CONFIDENT THE WEIGHTS AND VALUES ARE CORRECT?

CONJUNCTIVE PROCESSOR ”MULTIPLE HURDLES” APPROACH ALL IMPORTANT CRITERIA ARE CLEARLY IDENTIFIED CRITERIA CAN BE RANKED OR ORDERED IN IMPORTANCE CUTOFF LIMITS ARE SET FOR EACH CRITERION ALTERNATIVES ARE COMPARED TO THE CUTOFF LIMITS ONLY ALTERNATIVES WITHIN ALL CUTOFF LIMITS SURVIVE NOT AN OPTIMIZING PROCESS---NO SOLUTION GUARANTEED THE PROCESS MAY NARROW DOWN THE OPTIONS, BUT DOESN’T GUARANTEE A “BEST” SOLUTION WILL BE FOUND. IN FACT, IT IS POSSIBLE THAT ALL ALTERNATIVES MAY BE ELIMINATED BY THE CUTOFF LIMITS, LEAVING US WITH NO RECOMMENDATION. EXCEPTIONAL STRENGTH ON ONE CRITERION CANNOT MAKE UP FOR A WEAKNESS OR LACK ON ANOTHER CRITERION. ALL THE MINIMUMS ON ALL THE CRITERIA MUST BE MET.

THESE DECISIONS ARE MUCH MORE SUBJECTIVE THAN THEY APPEAR, AND ARE DIFFICULT TO DEFEND IF CHALLENGED.

GROUP DECISION MAKING ADVANTAGES • BROAD REPRESENTATION • TAPS EXPERTISE • MORE IDEAS GENERATED • EVALUATION OF OPTIONS • COORDINATION • HIGH ACCEPTANCE DISADVANTAGES • TIME CONSUMING • POSSIBLE INDECISIVENESS • COMPROMISE DECISIONS • DOMINATION BY A MEMBER • RISKY SHIFTS • GROUPTHINK
GROUP DECISION MAKING ISSUESVROOM & YETTON (73) • TIME AVAILABILITY • TYPE OF PROBLEM OR TASK • AVAILABILITY OF INFORMATION • NEED FOR ACCEPTANCE OF DECISION • LEVEL OF TRUST • CAPABILITIES OF SUBORDINATES • LIKELIHIID OF CONFLICT
PARTICIPATION IN DECISION MAKINGVROOM & YETTON (73) LEADERS HAVE THREE DECISION MAKING STYLES AUTOCRATIC CONSULTIVE PARTICIPATIVE FACTORS AFFECTING CHOICE OF STYLE: 1. CHARACTERISTICS OF THE PROBLEM HOW IMPORTANT IS THE QUALITY OF THE DECISION? IS THE PROBLEM WELL-STRUCTUERED? IS TIME CRITICAL? HOW IMPORTANT IS SUBORDINATE COMMITMENT TO THE CHOICE? 2. CHARACTERISTICS OF THE MANAGER DOES THE LEADER HAVE GOOD INFORMATION TO MAKE THE CHOICE? 3. CHARACTERISTICS OF SUBORDINATES WILL SUBORDINATES ACCEPT THE LEADER’S DECISION? DO SUBORDINATES SHARE THE ORGANIZATION’S GOALS? IS CONFLICT LIKELY AMONG SUBORDINATES (OVER THE CHOICES)? CAN THEY CONTRIBUTE GOOD INFORMATION TO MAKE THE CHOICE?
VROOM’S DECISION STYLES • A1 YOU SOLVE THE PROBLEM YOURSELF, WITH YOUR OWN INFORMATION • A2 YOU OBTAIN INFORMATION FROM YOUR SUBORDINATES, THEN SOLVE THE PROBLEM YOURSELF • C1 YOU SHARE THE PROBLEM WITH YOUR SUBORDINATES INDIVIDUALLY, WITHOUT BRINGING THEM TOGETHER AS A GROUP. YOU CONSIDER THEIR IDEAS, THEN MAKE THE DECISION BY YOURSELF • C2 YOU SHARE THE PROBLEM WITH YOUR SUBORDINATES AS A GROUP, COLLECTIVELY GETTING THEIR IDEAS, THEN YOU MAKE THE DECISION BY YOURSELF • G2 YOU SHARE THE PROBLEM WITH YOUR SUBORDINATES AS A GROUP. TOGETHER YOU ATTEMPT TO REACH A CONSENSUS ON A SOLUTION. YOUR ROLE IS CHAIR, AND THE GROUP’S SOLUTION SHOULD BE THE ONE IMPLEMENTED
DEFECTS IN GROUP DECISION MAKING • DISCUSSION LIMITED TO A FEW ALTERNATIVES (ONE OR TWO) • FAILURE TO REEXAMINE THE PREFERRED ALTERNATIVE FOR WEAKNESSES AND POTENTIAL RISKS • NO SEARCH TO FIND ADVANTAGES FOR OTHER ALTERNATIVES, AND NO SEARCH FOR WAYS TO MAKE OTHER OPTIONS FEASIBLE • LITTLE OR NO ATTEMPT TO OBTAIN EXPERT OR OUTSIDE ADVICE • A TENDENCY TO IGNORE FACTS AND OPINIONS THAT DO NOT AGREE WITH THE PREFERRED PLAN OF ACTION • NO CONTINGENCY PLANS ESTABLISHED IN CASE SOMETHING GOES WRONG • NO ATTEMPT TO LOOK AT THE SITUATION FROM A CONTRARY OR ANTAGONISTIC VIEWPOINT • LAUGHING AT DANGER SIGNALS; MAKING LIGHT OF INDICATIONS THAT ALL IS NOT PROCEEDING SMOOTHLY • LEADERS WHO DOMINATE DISCUSSIONS AND MAKE THEIR SUGGESTIONS EARLY, BEFORE OTHERS HAVE HAD THEIR SAY
SYMPTOMS OF GROUPTHINKJANIS (72) A VERY COHESIVE GROUP THAT IS LIKELY TO MAKE POOR DECISIONS • OVERESTIMATION OF THE GROUP ILLUSION OF INVULNERABILITY (Superiority) ILLUSION OF MORALITY • CLOSEMINDEDNESS RATIONALIZATION (Discounting Warning Signs) STEREOTYPED VIEWS OF OUTSIDERS (Not Trusted & Not Very Smart) • PRESSURE TOWARD CONFORMITY SELF-CENSORSHIP OF MEMBERS DIRECT PRESSURE APPLIED TO DEVIANTS MINDGUARDS (Don’t Let Others/outsiders Influence Us) ILLUSION OF UNANIMITY (Silence Means Agreement?)
REMEDIES FOR GROUPTHINK • ASSIGN EVERYONE THE ROLE OF CRITICAL EVALUATOR SENSITIZATION • LEADER MUST BE IMPARTIAL DO NOT INITIALLY STATE YOUR PREFERENCES • APPOINT AN INTERNAL “DEVIL’S ADVOCATE” • USE OUTSIDE EXPERTS TO CHALLENGE THE GROUP THEY MAY STRONGLY DISAGREE WITH WHAT YOU WANT TO DO • DIVIDE INTO TWO OR MORE SUBGROUPS TO WORK INDEPENDENTLY ON THE SAME PROBLEM HAVE EACH GROUP REPORT BACK • HOLD “SECOND CHANCE” MEETINGS TO REAFFIRM EARLIER THINKING AND DECISIONS HAVE A “CONFIRMATION” VOTE LATER
BRAINSTORMING USED TO GENERATE NEW IDEAS OR ALTERNATIVES RULES: • FREEWHEELING IS WELCOME --- OFFER ANY IDEAS THAT COME TO YOU • QUANTITY IS DESIRED --- DON’T WORRY ABOUT QUALITY OR RISK RIGHT NOW • NO CRITICISM OR PRAISE OF IDEAS IS ALLOWED • NO QUESTIONS OR DISCUSSION OF IDEAS --- THAT WILL COME AT A LATER MEETING • COMBINATION AND IMPROVEMENT OF IDEAS IS ENCOURAGED --- BUILD ON OTHER PEOPLE’S IDEAS AND SUGGESTIONS
NOMINAL GROUP TECHNIQUE • EACH MEMBER GENERATES A LIST OF THEIR IDEAS AHEAD OF TIME • IDEAS ARE SHARED WITH MEMBERS EITHER AS AN EXHAUSTIVE LIST, OR ARE PRESENTED ONE AT A TIME WITHOUT COMMENT • MEMBERS VOTE BY SECRET BALLOT TO SELECT THE “BEST” IDEAS WHICH THEY WANT TO PURSUE FURTHER • EACH ITEM IS DISCUSSED AND EVALUATED PUBLICLY (Pros and Cons) • FINAL VOTES ARE TAKEN BY SECRET BALLOT REDUCES THE EFFECTS OF POWER AND STATUS DIFFERENCES ALL MEMBERS CAN PARTICIPATE AND GET THEIR IDEAS BEFORE THE GROUP MEMBERS ARE NOT INTIMIDATED BY A DOMINANT MEMBER
DELPHI TECHNIQUE • CAN PROBE THE VIEWS OF INDUSTRY EXPERTS • MATRERIALS SENT TO PARTICIPANTS FOR REACTIONS • OPTIONS ARE INDIVIDUALLY WRITTEN AND SENT BACK • SUMMARIES ARE SENT OUT FOR FURTHER COMMENT • ROLE OF THE IN-HOUSE COORDINATOR IS CRUCIAL • THE “GROUP” NEVER MEETS TOGETHER • NO FINAL DECISIONS ARE “MADE” BY THIS GROUP THIS IS A “VIRTUAL GROUP” WHICH CAN BE INTERNET CONNECTED PROCESS GATHERS THE BEST THINKING & JUDGMENT OF EXPERTS SUCCESSIVE FEEDBACK REDEFINES AND FOCUSES IDEAS FINAL DECISIONS ARE MADE BY COMPANY OFFICIALS, NOT THE GROUP
