Introduction
• In this project, critical success factors approach will be
used in measurement of organizational performance.
• Performance: output/outcome at the end of a certain
period of time of an activity.
• Outcome: extents the organization reached its objectives.
• Performance measurement: evaluation of all efforts
made to achieve objectives.
2
• Critical success factors refer: posses to be successful in
the industry they work in.
Method
multi-criteria analysis techniques
•
Technique for Order Performance by Similarity to Ideal Solution (TOPSIS)
– determine ranking of the critical success factors.
•
Analytical Hierarchy Process (AHP):
– calculate the weights of critical success factors.
3
Step 1: Determining the factors that enable the
organization to be successful in its sector.
In this step, first the factors necessary for the organization to be
successful in its sector have been determined.
4
The factors considered for the example
organization in the project are as follows:
SF1: financing
SF2: brand image
SF3: effective advertising
SF4: pricing
SF5: customer satisfaction
SF6: distribution skills
SF7: managerial ability
SF8: consumer loyalty
SF9: low product cost
5
Step 2: Ranking of success factors
In this step, firstly, the factors that attribute a success factor as
“critical” have been determined.
Criteria (main factors) which are considered to determine the
“critical” of a success factor are as follows:
•
Strategic character
•
Create value
•
Priority of factor
6
In this step secondly, weights of factors had been calculated by the
AHP technique. In other words, relative importance has been
calculated.

comparisons of AHP

• After forming the pair-wise comparison matrix, weights of factors
have been calculated. In this project, weights vectors had been
determined as follows:

Calculate consistency of pair-wise
comparison matrix
• Calculate of consistency ratio (CR) as follows
10
Then consistency vector is formed as follows:
11
n indicates number of factors. The avarage value (
) of the elements in the
consistency vector is:
λmax
= 9,09807÷3 = 3,032576
The consistency index (CI) have been calculated using the following formula:
12
Depending on n number of factors, random index (RI) had been determined.
Random index obtained from the Table 4. For this example RI is 0,58.

• Consistency ratio (CR)
• CR is smaller than 0.10 pair-wise comparison matrix is consistent.
14
Ranking:
• After calculating weight of the main factors, ranking of
the success factors have been determined using
TOPSIS technique.
• The calculations have been made in Excel program.
15
Each success factor has been evaluated a number between 1-10. And,
each column (SC, CV, PF) have been summed (Table 5).

According ranking of success factors is as follows : First factor is SF09, second is
SFO6 and third is SF03 etc.

Step 3: Determining threshold value for determining critical
success factors
At this step, a threshold value had been determined so that critical success factors
have been selected from above in Table 7.
In this project threshold value was accepted 0.10
According to this value, these factors are:
•

Step 5: Determining organizational performance
At this step, performance of the organization has been calculated using critical success
factors weights (Table 9) and evaluation scale (Table 10) that provide in the literature.

There are five columns in Table 11.
• The first column: critical success factors;
• the second column: weight of critical success factors;
• the third column: evaluation level of each factor;
• the fourth column: numerical equivalent of the evaluation level and
• the fifth column: performance level of each critical success factor.
• calculation: factor weight and scale value had been multiplied.
25
• In the last row, general performance level had been determined,
• The sum of performance level of each factor in fifth column was yielded
general performance,
• This value takes a value between 0 and 1,
• If the value of the general performance level is close to 1, it means that
organizational performance is excellent
26
• If the general performance level value is close to 0, this means
that organizational performance is very bad,
• Of course, the decision and evaluation of organization
management are also important,
• In other words, whether the level is considered sufficient or
insufficient depends on the organizational management.
