(f) Time as a factor is con 
sidered although an actual cost function is not evaluated. 
Obsolescence of an instrument is not considered as very- 
serious but depreciation is a factor of concern. 
(g) While one member reported 
no consideration to Performance as a factor, others consider 
• this as very significant. 
(h) Geographical location is con 
sidered with emphasis in countries which are dependent on 
equipment, material (sometimes labor also) and even job 
sponsorship coming from abroad. However, these are 
generally job related. 
(i) One member indicated that a 
cost-benefit analysis is performed for development projects. 
II. 1. It seems that no Effectiveness model as such is used, 
although similar factors are taken into consideration in 
decision making in very vague empirical approaches by some. 
2. Performance/Accuracy is generally evaluated. The criteria 
are varied. Some follow U.S. Standard specifications. Some 
have their own patterns and tables of performance giving 
lists of areas mapped according to time taken, terrain type 
(for difficulty assessment), etc. 
Availability, Reliability, and Survivability are not considered 
by one of the eight. Sometimes limitations in the equipment 
and material cause limiting reliability in them. Survivability 
of a technique or its updating is dependent on the available 
fund. 
III . None reported using any Cost-Effectiveness model. 
IV. 1. Half of the members reported some form of Program Evalua 
tion Review technique being used. While for some, this is 
done in terms of the total production of the agency, for the 
others this is done with regard to some items (e.g., on 
imported equipment like aircrafts or plotting instruments). 
2. Only one member reported the use of a form of Critical Path 
Method. The others, although generally aware and conscious 
of the principles, do not use it in practice (use it intuitively). 
V. No Decision Theory is used apparently. The decisions are generally 
based on the experience and expertise of the management personnel. 
VL 1. Some form of production control is implemented by all 
respondents, which include routing, loading, scheduling, 
estimating, and expediting.
