Three Philosophical Statements

THERE ARE ALWAYS MULTIPLE

SOLUTIONS

FOR ANY GIVEN PROBLEM.

Every solution leads to a different set of problems.

Doing nothing is often the best solution.

Problem/Symptom/Solution Analysis

Research known solutionsfor each problem and symptom

Research rejected solutionsand analyze why

Brainstorm problems createdby each potential solution

Brainstorm additional solutions for each problem/symptom

Decision Analysis Defined

BABOK®: “Decision analysis is an approach to decision-making that examines and models the possible consequences

of different decisions. Decision analysis assists in making an

optimal decision under conditions of uncertainty.”

Page 9: Designing Alternate Solutions: How to Find Solutions That Meet Your Requirements

Decision Analysis Defined

WIKIPEDIA®:“Decision analysis (DA) is the discipline comprising

the philosophy, theory, methodology, and professional practice necessary to address important decisions in a formal

manner. Decision analysis includes many procedures, methods, and tools for

identifying, clearly representing, and formally assessing important aspects of a decision, for

prescribing a recommended course of action by applying the maximum expected utility action axiom to a well-formed representation of the

decision, and for translating the formal representation of a decision and its corresponding

recommendation into insight for the decision maker and other stakeholders.”

Page 10: Designing Alternate Solutions: How to Find Solutions That Meet Your Requirements

Decision Analysis Defined

TOM HATHAWAY:

“Decision analysis is an excuse for making the right decision.”

For decision analysis to succeed, the decision must be clearly articulated and known by all decision-makers.

Fill in the rules part of the table on the next page.

This real business rule defines the actions that can occur with respect to a loan application.

The loan decision depends on the following:

If the current debt load plus the request is greater than 4 times their gross income, then deny the loan unless their credit is excellent and they have been on the same job for over 5 years. If this is the case, approve the loan but request a co-signer. If the total new debt is less than 4 times their gross income, and their credit is excellent or good, approve the loan. If they only have good credit and have been in their current job less than 5 years, approve with a co-signer. Otherwise, deny the loan.

Paired Comparison Analysis

Identify a set of criteria that distinguish the solutions.

Weight the criteria by their relative importance.

Create a matrix listing potential solutionsas rows and criteria as columns.

Select a group of participants with the knowledge and authority to make decisions and assign each participant a vote (potentially weighted).

For each criteria, compare each solution with each other solution and allow the group to select the better of these two (ignoring all other options).

Symptoms of Solved Problems Are Benefits

EXAMPLE

P. People who use the Eisenhower Tunnel forget to turn off their lights.

S. The cops and other officials are wasting their time helping tourists get their car started.

S. Tourists are upset because their car won’t start.

S. A lot of cars in the parking lot have their

lights on.Problems and Symptoms are starting points for Cost/Benefit analysis. Additional benefits need to be brainstormed.

BP Air would like to expand its customer service from traditional phone and in-person to create a customer web site. This expansion would allow customers to manage aspects of their travel from reserving a flight to baggage retrieval at their final destination. As a plus service, we would like to help our customers book lodging and ground transportation from our secure internet site. book flights; make changes to existing flights, check-in and print boarding passes.

Our expectations are that this project will:• Lower Customer Service inbound calls (or at least shorten the calls)• Increase customer Check-in efficiency• Improve overall customer satisfaction• Reduce the current cost of Reservations sales• Increase Customer Retention by making it easy for customers to sign up for our

rewards program online

This project will encompass all work related to developing and provisioning the online reservation “booking” system for BP customers. However, it cannot involve any modifications or updates to the current airline database system. Also, it must interact with the database modernization project team to ensure compatibility.

Finance wants immediate full payment (or at least a 20% deposit) for flights booked online that accounts for all applicable taxes and service charges imposed by government, governmental agencies, airports, etc.
