MOTIVATION• Here is my current view on the unification of the many flavors of the month in the business
and management literature. . All of them can be regarded an subsets of Systems Dynamics and Boyd’s OODA Maneuver. For completeness I add Goldratt’s thought processes for change management. Of course, change management can be seen as a subset of System Dynamics. Donnella H. Meadows emphasizes the dynamics of change. She brings together the disparate views of systems. In her ‘Thinking in Systems’ she opens with a 1979 quote from Russell Ackoff:”Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other. I call such situations messes…. Managers do not solve problems, they manage messes.” I suggest that Ackoff’s managers were not fluent with Forrester’s Industrial Dynamics (1961).The work of Forrester, Sterman and, more recently, Boyd brings order to these “messes”. See especially Sterman’s Business Dynamics and the archived journals of the Systems Dynamics Society.
• I’ve minimized the Cynefin Framework content….it’s a subset of the OODA maneuver.• I recommend Chet Richards web site, Fast Transients. The name is most appropriate.• Change is a dynamic process as seen in OODA and Systems Dynamics, both supported by
Newton’s Calculus and “Laws” of Motion.

SUMMARY
CJMaday 2012
• Set Goals ( Legally, Ethically and Morally) Victory Money Mislead or Confuse Opponent Your Goal?
• Compare Goals With Current Reality – OBSERVE; then Work to Realize the Goals – ORIENT Yourself
• HOW?• Set your Strategy – What to Do? Make Changes that
Produce the Most Return.

INTUITIVE COMPETENCEand
SOFTWARE COMPETENCE • Rizzo points out– that humans handle small systems; such as cars,
bicycles, some aspects of flight and video games. This uses intuitive competence.
– that humans cannot handle large systems; such as open loop unstable aircraft, power plants, large airports, etc. This requires modeling competence (aka decision-by-wire or software competence)
CJMaday 2012
BACKGROUND• Forrester’s Industrial Dynamics -- 1961, Sterman’s Business
Dynamics -- 2000• Deming’s PDCA (including DMAIC) -- 1950’s …• Profound Knowledge• Hopp and Spearman, Factory Physics, 3rd Edition, 2008• Boyd’s O-O-D-A Maneuver – Implicit Cascaded Feedback Dynamics,
Intuitive Application of the Principle of Optimality -- 1996• Rizzo’s Model-Predictive Control -- 2010• Goldratt’s TOC & TP -- 1984 + …..• Casparis’ Management Dynamics -- 2004• Debra Smith’s The Measurement Nightmare -- 2000
CJMaday 2012
OVERVIEW
• Merge/Integrate Business Dynamics, Factory Physics, and O-O-D-A to form an innovative and winning strategy in competition. O-O-D-A contains much, if not all, of Sun Tzu’s Art of War and Deming’s Profound Knowledge.
• The term “dynamics” is used in the systems or engineering sense, continuous, discrete, deterministic, stochastic.
• Merge these concepts using a feedback control system framework to 1) confuse, outsmart, and overcome your opponent or 2) achieve your goal.
CJMaday 2012
APPROACHES AND TOOLS
• Decisions within decisions. Cascaded feedback system. Variation and Disturbances may be manageable.
• Qualitative and Quantitative approach to problem solving.
• Value Streams (Cash, Materiel, and Information)• Profound knowledge.• Intuitive (implicit) competence – small systems.• Software (explicit) competence – large systems.
CJMaday 2012
PDCA
• Deming’s Plan-Do-Check-Act. Can be enhanced by adding a 5th step, Evaluate, followed by a feedback loop to return to Plan. Chet Richards might refer to this as the PDCA “loop” with power.
CJMaday 2012
O-O-D-A
• Observe-Orient-Decide-Act• It is a loop that contains internal or cascaded
feedback.• Richards calls it a “loop” with power.
CJMaday 2012
O-O-D-A
• SET THE GOAL• OBSERVE Get and absorb all the information you can by whatever
means possible. This usually takes time, years even. Can we do it faster? We better!
• ORIENT – This is the essence of the process and is supported by the
Observe, Decide and Act contributions.. It is formed at least by genetic heritage, surrounding culture, experience and previous learning.
– The mind combines all or part of this background to form the “many-sided cross-references”, implicit and explicit, which then become a new orientation.
CJMaday 2012
O – O – D – A
• ORIENT (continued)– Seek out and find data that don’t fit your conventional wisdom or
biases….QUICKLY!!– Analysis and Synthesis
• Axiomatic Design– System– Project– Process– Product
• Optimization– Design of Experiments– Design of Components– Dynamic Programming– Linear Programming
• TRIZ CJMaday2012

O-O-D-A
• ORIENT (continued)– Profound Knowledge• Heuristics• Intuition• Insight• Similar to abductive reasoning, hunches, that is
CJMaday 2012
O-O-D-A
• DECIDE– Intuitive competence or implicit decision making (aka
agility) based on Observation, Orientation and Profound Knowledge.
– Explicit decision making based on System Dynamics modeling and simulation, Optimality Principle or Dynamic Programming, Design of Experiments, TOC, Lean, Six Sigma, TRIZ, Monte Carlo Methods et al. This can lead to software competence. Current computational speeds provide some agility.
– Set Strategy
CJMaday 2012
O-O-D-A
• ACT– Deception– Ambiguity– Generate surprise and panic– Seize the initiative and keep it– Practice, Test, and Evaluate• Equivalent to Complex and Chaotic Domains in Cynefin
Framework• Implement Tactics
CJMaday 2012
SYSTEM DYNAMICS
• System Dynamics– Model the system to be controlled– Controller dynamics – feedback– Simulation
• Software Competence• How does change occur?
CJMaday 2012
OVERALL GOAL
• CREATE DISORDER AND CONFUSION - OUTSMART THE COMPETITION - WINNING STRATEGY– Faster decision cycle-----air-to-air-combat, intuitive
competence– Different decision cycle-----outside the box – Decision-by-wire competence (System Dynamics)

• This diagram is not meant to be unique. It is a guide to be used in your situation. Essential features include feedback and Implicit Guidance and Control. It is qualitative and quantitative.

CJMaday2012
OVERVIEW
• TOC, Drum-Buffer-Rope and Critical Chain Project Management use buffer management such that the buffers provide the feedback signals that allow the control processes to successfully deal with variation.
• Is buffer feedback the reason for their effectiveness? IMO YES!
• CONWIP is a process that combines feedback and feedforward implicitly. Total WIP is controlled explicitly. An innovative and insightful approach; clever, that is!
MORE OVERVIEW
• Apply System Dynamics and OODA• Identify the problem, make sense of it• Use Cynefin Framework to categorize problem– Simple or Complicated = Small; Implicit or
Intuitive Decision Making– Complex or Chaotic = Large; Explicit Decision
Making -- aka Decision-by-Wire
CJMaday 2012
Some Necessary Requirements
• Profound Knowledge • Understand goal and context – choose form of
decision analysis• System Dynamics Model– Implicit and intuitive– Explicit computer model
• Feedback algorithm
CJMaday2012
WHAT NEXT?
• How to sell Software Decision Making?• How to model the system?
• HOW TO BRIDGE THE GAP BETWEEN SOFTWARE AND INTUITION ? (Many thanks to Jim Bowles for this input!)
