PRODUCTIVITY AT
COMPANY LEVEL

2. PRODUCTIVITY AT COMPANY LEVEL
The output at company level includes not only
quantitative measures such as turnover, profit, floor
area and market share, but also qualitative
measure.
To measure a company’s productivity, the overall
productivity level needs to be measured.
This means that productivity at company
(head office) and site level.

Other factors
that affect
productivity are:

project activities
Low Productivity influential Factors can be summarized
as:
ineffective delegation of responsibilities

15. PRODUCTIVITY AT COMPANY LEVEL
use of
inappropriate
tools/equipment
for different tasks
lack of
knowledge of
project
technology
interference by
management
poor site layout.

16. PRODUCTIVITY AT COMPANY LEVEL
Motivation
lack of re-
appraisal of
employees for
promotion;
resentment
regarding
management
policies;
lack of incentives
for good
performance;

17. PRODUCTIVITY AT COMPANY LEVEL
 lack of opportunities to exercise
skills/knowledge;
 slow response in settling
employee’s grievances;
 uncertainties about career
prospects;
 constraints on a worker’s
performance.

Training
lack of
experience
and training;
lack of contact
administration
skills;
poor
knowledge of
scientific skills;

19. PRODUCTIVITY AT COMPANY LEVEL
insufficient
knowledge of
new
technologies;
shortage of
multi-skilled
project
personnel.

21. PRODUCTIVITY MEASUREMENT-PERFORMANCE
ABILITY RATIO
(P.A.R)
 Performance is a ratio of
accomplishment to methods.
 the worth of performance is the value
of the accomplishment divided by the
cost of the methods.

22. PERFORMANCE ABILITY RATIO
(P.A.R)
 The measurement of worth of a
particular crew’s performance is more
than just calculating how it is worth
relative to cost.
 It therefore becomes essential that a
crew’s performance be compared
against a yardstick of acceptable
standard.

23. PERFORMANCE ABILITY RATIO
(P.A.R)
 Time study can help to establish standard
time, although it is expensive and time
consuming.
 Contractors establish estimated rates
based on past experiences, to form their
bases of estimation for new jobs.
 To overcome this problem exemplar
performance has been introduced to
management team.

24. PERFORMANCE ABILITY RATIO
(P.A.R)
 PAR= Exemplar Performance/Current
Performance
 There are a number of ways in which P.A.R can
be used.
 One such a way is the comparison between
current performance and exemplar.
 This will give a measurement of site worker’s
performance.
 PAR=1 It means current work is equal to exemplar
 It is hardly possible for any firm to maintain it.

25. PERFORMANCE ABILITY RATIO
(P.A.R)
 PAR>1 it means there is
potential for improving the
performance
of the crew on site.
 PAR<1 Is an indication that a
company’s performance is
above Average.

26. PERFORMANCE ABILITY RATIO
(P.A.R)
PAR also can be shown as:
 PAR= Exemplar Performance/Weekly
Average.
 The Exemplar Performance can be
measured from daily productivity rate
against weekly average productivity.
 Student to read about:
 Factor models-Project leadership model -
Action response model.
