TYPES of WORK

Project: a series of activities to be executed by more than one specialist group acting in a temporary (begin-end) co-operative relationship directed at a specific result to be attained within a certain time and with defined resources. Project Management: the managing of a set of activities, directed at a specific goal, which are executed once only within a limited time, with certain humans resources and with a certain budget.

Improvise Project Routine

New object Unknown results Problem oriented Unconscious Intuitive / ad-hoc Flexible approach Open structure/ intuitive management

New object Planned results Result oriented Once, unique Rules Planned approach Temporarily structure/ project management

Known object Known results Means oriented Repeated Standard rules Standard approach Standing structure/operational management

TOC is all about time management, becomes vivid in project management

A revolution in Time Management: critical chain

2 problems for overruns: - Multi-tasking: shifting between tasks and/or projects - Student Syndrome: start too late (have time enough), and

unforeseen problems can often not be resolved on time

Via the 5 focusing steps: - Critical Chain (CC) vs. Critical Path (PERT) - Focus on one task (no-multi-tasking) - Staggering: prioritizing projects (multi-project context) - Project Buffer, no task protection but for WHOLE project - Feeding Buffers for non-critical paths into the CC - Buffer Management

Critical Chain = longest chain of depending steps (time & resources) Note: Critical Path only takes time in consideration

Summary

38

There is plenty of safety embedded in projects but it is masked and wasted due to our mode of operation.

It is not important to complete each task on time, it is essential to complete the project on time.

Get consensus to stagger projects.

Quotes of Goldratt


39

Bad Multitasking The dropping of work on one task before it is finished in order to start another.

Parkinsons Law The satirical statement that work expands to fill the time allotted to it.

Students Syndrome The type of procrastination students are prone to when they are assigned a project or are facing a test.

Common Cause Variation a source of variation caused by unknown factors that result in a steady but random distribution of output around the average or mean of the data

Special Cause Variation variation caused by known factors that result in a non-random distribution of output; also referred to as "exceptional" or "assignable" variation.
