academic achievement is Regents’ diploma rate: the percent of
students receiving a state diploma by passing eight Regents’ exams.
Lead indicators are short-term and process-oriented. Starting in 2000,
the lead indicator for the Regents’ diploma rate was performance on
new fourth and eighth grade state tests.
Finally, annual projects are defined, based on cause-and-effect
analysis, that will improve performance. In 2000–2001, four projects

A personnel department wanted to improve social activity within the company in order
to increase loyalty levels. A theory was put forwards that soft-skills training contributed
significantly towards this in-house socializing. The personnel manager consequently
decided to use a Matrix Diagram to investigate this. The steps taken were:
Objective: Investigate effect of soft-skills training on social activity.
Matrix: T-matrix, with people on main stem, in-house training courses to left,
attendance of social clubs to right, plus an extra column for years of service.
Comparison: In-house training - tick for attendance within last three years; social
clubs - three bands corresponding to under 30%, 30% to 70% and over 70%
attendance in the same period.

The resultant matrix, showed that people with higher levels of
social training also tended to be more committed members of
social clubs. It was also noticed that there seemed to be a
particular increase in commitment after going on the team-building
course. The length of service showed no particular pattern.
As a result, the training was expanded, and people were given
more encouragement to attend (particularly the team-building
course). This resulted in a steady increase in social activity and a
reduction in attrition rates.

PRIORITISATION MATRIXPRIORITISATION MATRIX
This tool is used to prioritize items and
describe them in terms of weighted
criteria. It uses a combination of tree and
matrix diagramming techniques to do a
pair-wise evaluation of items and to
narrow down options to the most desired
or most effective.

Pay and work overload, as the highest scoring motivational
problems, were selected for carrying forward for further
investigation. As a result of consequent work in the project,
the pay structure for certain grades was revised and training
on job scheduling was introduced. In the following year, the
survey improved in these areas by 2 and 3 points,
respectively.

PDPCPDPC
A useful way of planning is to break down tasks
into a hierarchy, using a Tree Diagram. The
PDPC extends the tree diagram a couple of
levels to identify risks and countermeasures for
the bottom level tasks. Different shaped boxes
are used to highlight risks and identify possible
countermeasures (often shown as 'clouds' to
indicate their uncertain nature). The PDPC is
similar to the
Failure Modes and Effects Analysis (FMEA) in
that both identify risks, consequences of failure,
and contingency actions; the FMEA also rates
relative risk levels for each potential failure
point.
http://en.wikipedia.org/wiki/Seven_Management_and_Planning_Tools#Interrelationship_Diagraph
32. ProcessProcess
PDPCPDPC
From the bottom level of some activity box, the PDPC
adds levels for:
•identifying what can go wrong (failure mode or risks)
•consequences of that failure (effect or consequence)
•possible countermeasures (risk mitigation action plan)
http://en.wikipedia.org/wiki/Process_Decision_Program_Chart
33. ExampleExample
PDPCPDPC
A dress production team at a clothes manufacturer was
improving the cutting-out process in order to minimize
material wastage. They decided to use PDPC on the work
breakdown structure to identify potential problems and ways
of avoiding them.
As the most expensive element is the material itself, they
defined a significant risk as, 'Anything that might cause the
cut cloth to be ruined', and viable countermeasures as,
'Anything that will reduce the risk, and which costs less than
100 pieces of cloth' .

35. ExampleExample
PDPCPDPC
http://syque.com/quality_tools/toolbook/PDPC/example.htm
As a result of this, the cutting was tested on cheaper
material, resulting in the material clamp being redesigned to
prevent drag, a start notch provided for the cutter and the
general area being inspected for sharp corners to minimize
snag problems. The cutting operator was involved in the
PDPC process and the subsequent tests, resulting in her fully
understanding the process. The final cutting process
thereafter ran very smoothly with very little error.

This tool is used to plan the appropriate sequence
or schedule for a set of tasks and related
subtasks. It is used when subtasks must occur in
parallel. The diagram enables one to determine
the critical path (longest sequence of tasks). (See
also PERT diagram.)

ACTIVITY NETWORK DIAGRAMACTIVITY NETWORK DIAGRAM
Drawing the Network
List all the necessary tasks in the project or process. One convenient
method is to write each task on the top half of a card or sticky note. Across
the middle of the card, draw a horizontal arrow pointing right.
Determine the correct sequence of the tasks. Do this by asking three
questions for each task:
Which tasks must happen before this one can begin?
Which tasks can be done at the same time as this one?
Which tasks should happen immediately after this one?
It can be useful to create a table with four columns —prior tasks, this task,
simultaneous tasks, following tasks.

Diagram the network of tasks. If you are using notes or cards,
arrange them in sequence on a large piece of paper. Time
should flow from left to right and concurrent tasks should be
vertically aligned. Leave space between the cards.
Between each two tasks, draw circles for “events.” An event
marks the beginning or end of a task. Thus, events are nodes
that separate tasks.

Look for three common problem situations and redraw them
using “dummies” or extra events. A dummy is an arrow drawn
with dotted lines used to separate tasks that would otherwise
start and stop with the same events or to show logical
sequence. Dummies are not real tasks.

In the activity on arrow (AOA) diagram each
activity is represented by an arrow connecting two
circles (nodes)
The nodes represent transitions between activities –
referred to as events
The duration of an activity is written by the arrow
representing it.

four days, between events 1 and 2.
