The company is rendered “Directionless”!!!!!
HR
PPC
Sales

Manufacturing
Each department would like decisions to be made in a different direction!
What decisions to make?

Why is the company rendered “Directionless”?
• Performance Targets are set for each function so as to get desired behaviour to control financial and operational elements.
• Unfortunately, an action which has positive impact on one element creates negative impact on some other element. For example:• Reducing inventory may result into unavailability of
materials for production thereby increasing lead times.• Trying to deliver on time may result in sacrificing quality
or increase in costs.• Management is continuously engaged in doing a tight rope
walk to achieve balance between these elements.• The strategy of the company based on its Vision and Mission is
lost in the process.

Why is the company rendered “Directionless”? (Cont..)
The Company is continuously struggling to reach a balance between Sales and Cost…
We do not have a mechanism to know what is the optimum balance among sales and cost related elements.
As a result it becomes impossible to get consensus of all functional heads for the target levels of all the elements together.

What is the conventional way of managing a company?
• Decide a Vision and derive the Mission for the company
• Prepare the Annual Business Plan based on goals and objectives it strives to achieve
• Divide the goals and objectives and distribute it to the departments
• The departments set annual targets and distribute the same to there functions
• Each department/function initiates multiple improvement programmes to achieve desired objective
What is the hidden assumption?The Assumption
Sum of improvements in each part of the system.
Overall improvementin the system.

But is the assumption true?
No!! The additive rule does not apply when the components in a system are interdependent
To analyze and manage organizations, the four fundamental principles of Theory Of
Constraints have to be applied!
Is there another way to manage an organization?

I smile and start to count on my fingers: One, people are good. Two, every conflict can be removed. Three, every situation, no matter how complex it initially looks, is exceedingly simple. Four, every situation can be substantially improved; even the sky is not the limit….
