About This Presentation
The Thinking Processes of Goldratt's Theory of Constraints enable decision makers to improve and even transform their in-live systems - process-oriented organizations or problems to be solved - with an minimum of effort.

1. Digital Maturity
Theory of Constraints – The Scope
Domain-specific
applications
Management system and
problem solving tool set
Efficient operativions of an in-
use system
• Production
• Project management
• Accounting
• Logistics, etc.
Effective system improvement /
reconfiguration
• Strategy development
• Change management
• Planning (strategical / tactical)
• Go-to-market
3
1. Digital Maturity
End-to-end thinking – Focus on the intended result
A purpose system‘s task is to deliver the maximum output.
The Thinking Processes consider and tackle
• Dilemata
• Decision making problems
• Questions to be answered, etc.
as flow problems.
Throuput: Performance rate at which a purpose system (an
organization) achieves its goal.

2. Impacts
Focusing on one core control parameter
Identification of the constraint
• Pivotal system parameter
• What is the limiting factor which hinders throughput?
• Where does the problem solution stall?
Types of constraints
• physical (also the market)
• political (e.g. a policy)
• psychological (e.g. a bias or an impasse)
5
2. Impacts
TOC‘s Thinking Processes at a glance
The Thinking Processes enable
• problem solving in complexe environments
• support decision making
• development of strategies and tactics
They answer three deceptively simple questions
1. What to change?
2. To what to change?
3. How to cause the change?

• The <requirement>
that we want to satisfy
by the <action>.
resp.
To satisfy this
<requirement>, we
have to achieve this
<prerequisite>.

• Valid arguments as to why an action is required to satisfy a need.
• Assumptions are the
key to the solution.

• Cross check: Do

jeopardize each other?
• Is the conflict really
a conflict – do
the prerequisites
contradict each other?

3. Becoming Agile
ToC-Thinking Processes vs Agile
Similarities with agile approaches
• Current system as the starting point
• disciplined approach
Differences with agile approaches
• T oC also clarifies objectives and vision
• Defines target state ex ante
• Blue O cean strategy

3. Becoming Agile
Evaluation: ToC-Thinking Processes
Scope: Answers all key questions
• What to Change?
• T o what to Change?
• How to Change?
Benefits
• Comprehensive management philosophy
• Robustness
Pragmatism combined with systematics
• Easy communication of results
• Danger of the illusion
of understanding
Shit In, Shit O ut
• Discipline and practice
