Title: Objectives:
1More Definitions
- Objectives
- It is a specific thing that you want to achieve
- Decision making can be guided by one or multiple
objectives - Values
- An individuals objectives taken together make up
his or her values - Outcomes
- The possible things that can happen while trying
to resolve an uncertain event through a decision
analysis process
Ref slides from Dr. Loerch
2More Definitions (contd.)
- Information
- Information relates to a specific decisionit is
what the decision is based on.
Information can be measured as the probability
that the preferred choice in a specific decision
with specific alternatives will lead to the
outcome most desired from among the outcomes
actually achievable from the available
alternatives
3Strategic decisions involve four critical
components
Values What do we want?
Future What could happen?
Information What do we know?
Alternatives What can we do?
- Understanding of the future is critical to all
three elements. - Use strategic values to identify future
decision opportunities.

6Types of decisions
Static Decision
- One time decisions
- Analysis performed only once
- Sequential decisions but Analysis performed only
once - Dynamic Decisions
- Analysis performed more than once
- Time is a factor
7Decision Analysis For System Design
- The purpose of a design is
- To solve a problem
- To overcome a shortcoming
- To improve a situation
- Design involves decision making
- The same procedures that provide a framework for
other decision processes work for design
decisions as well
8Measurement
- Most important step in analysis - What should be
measured? - Goes by many names
- Measure of Effectiveness (MOE)
- Measure of Performance
- Measure of Merit
- Objective
- Measure of Benefit (vice Cost)
- Metric
- Must reflect outcome of decision
9Risk
- Definition (Oxford English Dictionary)
- Exposure to the possibility of loss, injury, or
other adverse circumstance - Risk is the variability in our estimation of the
outcome of a choice, including both better and
worse-than-hoped-for events. - Three Issues
- How bad could it get? Must measure bad outcome
in some sense - How possible is the bad outcome? Need probability
distribution on possible outcomes. - How much do I care? Risk attitude of decision
maker
10-
- Decision Analyst
- vs
- Decision Maker
11Purpose of Decision Analysis
- To provide insight to the Decision Maker
- Not make the decision for him/her
- Difference between Decision Maker and Analyst
- 3 things that a decision maker can do with your
analysis - Use it
- Modify it
- Throw it away
- Do a good job and dont worry about it!
12Analysts need to better understand
decision-making process
Political
Rational
Emotional
13Interacting with Decision Makers
- We as systems engineers and analysts are seldom
the decision maker! - Understanding
- Senior level decision-making
- Senior decision-makers
- Decision analysts
- Presentations to senior decision-makers
- Discussing potential new analyses
- Obtaining approval for analysis plan
- Providing a decision briefing
-
14- Who are Decision Makers ?
15Characteristics of Decision Makers
- Busy
- Difficult to see
- Gatekeepers control access
- Establish vision and strategic objectives
- Interested in how your idea fits with their
agenda - Knowing their objectives is valuable
- Control resources
- Analysis champion requires their approval
- Their support is usually critical
Get access to senior leaders early in the
analysis and at key decision points.
16Senior decision-makers need to better communicate
with analysts
- Define the problem
- Describe the desired product
- State the need date
- Identify the constraints
- Provide resources
17Three proven guidelines to successful
presentations to senior leaders
- Allow time for the senior decision-maker to talk
- Once you are in let them determine how long you
stay - Use fewer and better slides
- Use 10-15 slides for 30 minutes
- Always state (restate) the problem/issue/challenge
- Put a summary of the key message on every chart
- Brief the message
- Seek first to understand then to be understood
- Listen to the question
- Answer questions briefly and clearly
- Make sure you are working the right problem.
18Decision analysts need to provide executive
summary presentations to senior decision-makers
- When the analysis is finished you are 50 done
- Pre-brief key advisors
- Incorporate their comments and suggestions
- Used more detailed briefings
- Do not use your own perceptions
- Summarize the results of your systematic analysis
- Tell what is means to the decision-maker
- Keep the charts clear and concise
- Tell a story
- Avoid extraneous information
Bring the decision-maker through the front
door.
19- Extensively use graphs, colors, and pictures
- A picture speaks a thousand words
20- Extensively use graphs, colors and pictures
- Example 1
Cumulative density function
21- Extensively use graphs, colors and pictures
- Example 2
- Chart displays the potential range of value
- Range increases and value declines with volume
22- Extensively use graphs, colors and pictures
- Example 3
Colors can be used to highlight the differences
in the 5 alternatives.
23Summary
- Communicating with senior managers
- Get access early and often
- Make sure you are working the right problem
- Respect their time
- Need to remind them of your project
- Provide executive summary briefings
- One chart summary
- Three communication opportunities
- Get started understand the decision-makers
problem - Obtain approval for work plan - systematic
approach - Provide a decision briefing - tell a story
24Definition
- Consequence
- Its the final fate of the Decision Maker
25Time value of Money
- If an investment at 10 inflation yields 110
after 1 year its present value (PV) is - PV X
- (1r)n
The net present value is NPV PV of returns on
investment investment If you invest
100 for 1 year at 10 interest, you will earn
100(1.1) 110. The PV is 110/(10.1)100. NPV
100-100 0. The interest earned (10) has
been adjusted for inflation.
26Time value of Money
- The return on 425 investment is
- Year 1 2 3 4
- Return 110 121 133.1 146.41
- Assume inflation 10
- Is this a good investment?
- Total return 110121133.1146.41 510.51
27Time value of Money
- Calculate PV
- PV 110/(10.1) 121 /(10.1)2 133.1
/(10.1)3 146.41/(10.1)4 - PV 100100100100400
- NPV PV investment 400-425 -25
- Its not worth investing!!
