6. Why invest in er gonomics?
The status and value of ergonomics in a companycan be determined by answ ering the following questions:
Does the organization have problems w ith: yes no
i nc re asing m anufac tu ri ng costs
i nc re asing c os ts fo r main tenanc e a nd re pa ir
d ec re asing p roduc t qual ity
s uscep tibi li ty to pr oduc tion br eakdow ns
k eeping to dead lin es
c ustomer sati sfac tion
Does the organization w ant to:
improve safe ty at w or k
r educ e i llness-r elated absenc e (e.g . for back p ro blems)
m ot ivate
improve the w el l-be ing o f employees
Is the organization planning to: r es tr uc tu re the w or kp laces i nsta ll new fac il it ies i nt ro duce n ew manu factu ring sequences and e qu ipment
If several of the questions w ere answ ered w ith "yes", there is probably a need for ergonomic improvements in the organization, andthe next steps are as follow s:
Using t he ques tionna ire in chapter 10, pinpoint the w eaknesses o f t he w or kp lace a nd analyze them. Formula te goals. Dec ide w ha t a c tion to take. Calc ulate the i nves tment re qu ired and c ompare .

??
What are the benefi ts ofergonomics?
1. Well-being in the work placeIf all aspects of the workplace, inclu-ding the nature of the work, its orga-nization, the environment and the
space available, are in accordancew ith the abilities of the individual, thenthe condi t ions for maximum worksatisfaction have been met.
2 Less il lness-related absencesWhere w orkplaces have been ergono-mically designed there are less acci-dents and bodily c omplaints, so thereare less days lost.
3 Higher productivityA human-engineered wor kplace is thebasis for increased motivation andperformanc e by its user.
4 Better business resultsThe holistic inspection of the w orkpla-ce and the optimum implementation ofergonomic expertise lead to betterbusiness results.
Why i nvest in the Leica er gonomicsprogram?
The investment in the sensible planning of microscopy work
stations brings benefits to employee and employer alike if all
involved (user, planner, wor k-scienc e spec ialist, medical spe-
cialist and microscope manufacturer) cooperate to introduce
measures to reduce specific stresses. As microscope manu-
facturer s, we c an design our instruments so as to minimize the
stresses on the user and therefore to promote better
working. Leica has therefore given more thought than any
other stereomicroscope manufacturer to this subject and has
created a r ange of ergonomic ac cessories (see section 5). It is
now up to the organization to make use of the opportunities
offered. The higher initial investment in ergonomic c onditions
pays off in healthier, more contented employees, and also in
higher productivity and improved performanc e.

The Leica ergonomics program employee andemployer both gain
The Leica ergonomics program
prevents a forced posture, t i redness, reduced performance and bodily
discomfort.
offers better, healthier view ing conditions through the options of adapting the
eyepoint individually and of c hanging the posture at any time.
reduces static exertion during precision work, because the arms and hands
can be supported.
improves visual work, because the high-quality optical system does not sub-
jec t t he eyes to the s tr ain o f a ccommoda tion .
enables the user to concentrate and w ork for long periods at a time.
The advantages for the company:
Higher productivity
Better quality
Lower costs
Less absenteeism
Greater safety
M ore rel iable
Competitiveness
Better business results.
