SYS 2001 Midterm

1. Determine goals of system

2. Establishing criteria for ranking alternatives

3. Develop alternate solutions

4. Rank solutions

5. Iterate

6. Action

effectiveness must be evaluated by its accord with general social, governmental, or other high-order judgments, rather than by simple economic efficiency

A large number of discernible subsystems or parts. May be interconnected in complex ways

A goal-centered approach

Locks-in current technology and operational structure, produces ever-decreasing incremental improvements, tends to focus on short-term problems

It is a powerful aid in getting the study started, it minimizes fear of making initial errors, it minimizes wasted effort on unnecessary subtasks and extraneous dead-ends

When the additional cost of one more iteration exceeds the probable benefit of the additional clarification

Generalize the question, develop a descriptive scenario, develop a normative scenario, develop the axiological component, prepare an objectives tree, validate, iterate

Describes the situation system as is, used to help broaden the analyst's understanding of the generalized component, points out current good and bad features of the system

Reading down any branch of an objectives tree, each goal statement must answer ‘how’ for it’s immediate superior goal, Reading up any branch, each higher statement answers ‘why’ the goal below it is needed, Each goal statement should provide a more detailed goal than the statement above it in the hierarchy, should NOT give solutions

allows analysts to include considerations such as impacts on non-users and the environment, It helps to address the issue of a client often not understanding their own problem, allows the analyst team to consider a greater portion of actors involved within a system

Infer based on other interactions and questions

Measurable, subjective, nonrelativistic, meaningful, understandable

Simple interest is a fixed percentage of the principal amount that was borrowed or lent; compound interest accrues and is added to the accumulated interest of previous periods

no criticism, build on each other's ideas

Improvement over brainstorming, absolute silence, built off of trigger questions2

Client's values are (figure out from behavior)

application of scientific method

negative principal paid minus interest paid

multiply by interest rate from the top diagonal of outstanding cost

i*n = 72% Easy way to figure out how long it will take money to double

Directly from clients/system, indirectly from clients/system, internal research, external research, from your team
