6. THE
ESTIMATING
DILEMMA
If each task is given more time, it will prevent any
task delays, but then the project end date will be
delayed
The project will end sooner if I give myself less time, but
it is more likely to overrun
But we have to deliver the Project on time
Parkinson’s Law, Murphy’s Law and Student’s Syndrome
06
7. HOW MUCH TIME
SHOULD A TASK BE
ALLOTED IN A
PLAN?
The amount of time a task should take on average for
a focused average performer
PLUS, The time we expect to be spent on distractions
• The difference between mediocre and poor performers
• Our uncertainty in the average time
• Our uncertainty in the time for distractions
• How risk-averse we are or have to be
07
PLUS, A contingency time to take account of
8. If we set our estimates so that we are 90% sure that any task will be completed on time
If we have 20tasks in our Project
The Probability that all the tasks will be on time is: 0.920 = 12%
For 50 tasks, the Probability of all on time is: 0.950 = 1%
Some simple maths
So,therehastobeabetterway...
08
9. PLANA PLANB PLANC
INVEST OUR ENERGY IN REDUCING THE VARIABILITY COPING BEHAVIOURS FIND A DIFFERENT APPROACH
Allowing longer in Project planning stage for estimates Fight to be assigned the most viable Projects
We can reduce variability, but
we cannot eliminate it, because
it is inherent to the nature of a
project
Training staff in estimating Fight for the best staff
Measuring progress and feeding results into estimation Fight to keep the Project scope down
Use of formal estimating methods Exploit scope changes to extend timelines & budgets
More detailed specifications Sandbag Project plans to create headroom
Less flexibility over changes to specifications Quit long Projects well before the delivery date
Training the staff better in their job content Disregard targets they know to be impossible
Identify poor performers using individual performance measures Staff work double shifts in the final weeks / months
Shorter projects, breaking larger projects into several short ones Dumping the blame elsewhere
Doing this can help, but doesn't solve the problem These may help individual, but not the org.
We must manage remaining
variability
09
10. HOW TO HANDLE VARIABLITY
IN CRITICAL CHAIN
We do not build in any contingency at the Task level
We move all the contingency to the Project level - this
is the Completion Buffer
Individual Tasks can now be late without affecting the
completion date of the Project
The Project due date is protected as long as the
cumulative delay along any one chain is less than the
completion buffer
10
11. HOW DOES THIS AFFECT THE
PROBABLITY OF BEING LATE?
Under 'normal' practice, if any task is later than its
contingency allows, we have a problem
Under Critical Chain, we only have a problem if
the total delay exceeds the total contingency
This second condition is much less likely than the first
[Law of averages / Central limit theorem] and
increasingly so as the number of tasks increases
11
12. The Completion Buffer
A Buffer is a block of time which protects a
deliverable from being affected by delays
upstream. The Completion Buffer protects the
Project completion date.
Over the course of the Project, we expect our
buffers to be used up, in proportion to progress
made
Scarcity of Resources
In putting together, the plan, we must consider
the scarcity of resources
If two tasks want exclusive use of the same
resource, at the same time, they must be
staggered
This affects the plan in a similar way to the task
dependencies
12
13. Task A – 10 D
Task C – 10 D
SCARCITY OF RESOURCES
Project Time Required - 20 D
Task B – 10 D
Task C depends on both A and B
Each task uses a different resource
13
14. Task A – 10 D
Task C – 10 D
Task B – 10 D
Project Time Required - 30 D
Resource conflict
Task C depends on both A and B,
Both A and B need exclusive use of
the same resource
SCARCITY OF RESOURCES
14
15. THE
CRITICAL
CHAIN
We identify the longest chain of dependent tasks by
resource through the Project - this is the Critical Chain,
at the end we place the Completion Buffer
The time taken to complete the Project is the time taken to
complete the Critical Chain
Any delay in the Critical Chain delays the Project
completion
15
17. In Practice
The buffer is 25-33% of
chain length
Completion Buffer
Project duration held constant
Task A
Task C
Task B
Task A
Task C
Task B
17
18. FEEDING CHAINS
All the other chains of tasks we call Feeding Chains,
because each one at some point feeds into the Critical
Chain
Every task in the Project is part of either the Critical
Chain or a Feeding Chain
FEEDING BUFFERS
We must not allow anything to delay the Critical Chain
We must protect the critical chain from being delayed by
lateness in the Feeding Chains
We start the feeding chains a little early and insert a block of
time to decouple the Critical Chain from each Feeding
Chain
We call these blocks of time Feeding Buffers
18
20. There is no
contingency at
task level
The Project due
date is protected
by the a block of
time called the
Completion Buffer
The Critical Chain
is the longest chain
of tasks through
the Project
All other chains
of tasks are
Feeding Chains
We place
Feeding Buffers
to decouple the
Critical Chain
from the feeding
chains
PLANNING PHASE SUMMARY
20
21. EXECUTION PHASE
We have a great plan - what can happen in execution?
Critical Chain in Execution phase
No multi-tasking - when someone starts a task, they stick to it until it's completed
21
22. VERY BAD
MULTI-
TASKING
When someone stops doing a task on the Critical
Chain, and starts doing something else, they are
delaying the entire Project
MORE BAD
MULTI-
TASKING
If we have two people, each available 50% to our
Project, and they have to work together, they are
effectively 25% available
If we have four such people, it's effectively 6%, so we'll
wait on average 8 working days to get them together
for half a day
Real-life case: Ten team leaders, each on 50%
availability: Out of two Project meetings, 3 came to
both, 5 to one or the other, 2 to neither
BAD MULTI-
TASKING
Whenever I put down one task and pick up another, I
lose productive time
How much time is lost switching depends on how deep
or shallow the task is
Putting a stop to multi-tasking in effect creates extra
capacity
22
23. CRITICAL CHAIN IN
THE EXECUTION
PHASE....
No multi-tasking - when someone starts a task,
they stick to it until it's completed
We begin each task as soon as resource is
available and prerequisite tasks are complete
The timings in the plan are for planning, not a
commitment on execution
Early finishes on Critical Chain tasks bring
forward the whole Project
We finish each task as soon as we can
Early finishes on Feeding Chains increase the
protection of the Critical Chain
Sometimes we call these three together
'ROADRUNNER' style
23
24. PLANNING PHASE
The Project is
analyzed into the
Critical Chain and
Feeding Chains
No Multi-tasking Early finish /
allowing early
start of following
tasks
Subordination

Chain
SUMMARISING PRACTICAL DIFFERENCES...
Contingency is aggregated
into a Completion Buffer
protecting the Project end-
date, and Feeding Buffers
protecting the Critical Chain

A (8 DAYS)
Measures &
Management
Making less progress than planned will
eat into the Completion buffer
Making more progress than planned will
add to the Completion buffer
At day 5, task A has 8 days
remaining (of 10) –
Completion Buffer is eroded by 3
days
Task D is completed - no effect on
Completion Buffer
3 DAYS

29. We comparethepercentageoftheCompletionBufferRemaining (%
CBR) withthepercentageoftheCriticalChainRemaining(%CCR)
We settriggerpointsforcorrectiveaction,forexample:
When the ratio % CBR / %CCR is 1or more, Project status is
GREEN- Watch
When %CBR / % CCR is between 1and 2/3, Project status is
AMBER- Preparearecoveryplan
When %CBR / % CCR is less than2/3, Project status is
RED- Implement recoveryplan
CORRECTIVE
ACTION
29
31. DON'T OVERREACT TO BUFFER EROSION
If we have 2/3 of the completion buffer left and only 1/3 of the Project to do we are doing fine
We expect our buffer to be used up over the course of the project
Our date is not threatened if the buffer is used up in proportion to progress
Our date is threatened if the buffer is used up disproportionately
If we have 2/3 of the Project still to do but have only 1/3 of the completion buffer left we have a problem
31
32. We have simple,
objective measure of
Project progress
We have a simple rule
for triggering - and not
triggering - corrective
action
MEASURES SUMMARY
We have a simple,
objective measure of
Project health status
We can redefine the
Project progress meeting
as the Buffer Management
Meeting- corrective action
32
33. BUFFER MANAGEMENT MEETING
Attendees
Project Manager, Project Sponsor / Owner, Task
Managers, Resource Managers
Agenda
• Reminder of what tasks are on the Critical Chain.
• Review Project status ( % Critical Chain outstanding)
• Review Completion buffer status (Red, Amber,
Green).
• If necessary, initiate corrective actions.
• Review Feeding buffers status (Red, Amber, Green).
• If necessary, initiate corrective actions.
• Review tasks in progress to ensure earliest
completion in full.
• Review tasks not started to ensure earliest start
where appropriate.
33
34. USING BUFFER MANAGEMENT TO
DRIVE ONGOING IMPROVEMENT
• Buffer Management measures are fact-based and
objective
• Buffer Management meetings highlight buffer
erosion / Project delays
• Preventing the causes of delay will speed up your
Projects
• Your process of ongoing improvement is simply to
eliminate the causes of delay by following up on the
issues highlighted in Buffer Management meetings
• As your Projects run faster and more reliably,
continue to eliminate more and more causes of
delay
34
35. HOW DOES CRITICAL CHAIN HELP OUR PROJECT MANAGEMENT ?
Aggregated contingency and 'Roadrunner' style
Effective due-date protection and extra effective capacity
More reliable on time in full to budget delivery performance
Buffer measures
Objectivity and clarity
Better focused meetings, better directed recovery efforts, better
informed stakeholders, less waste and more productivity
Less encouragement of 'coping behaviors'
