4. CONCLUSIONS AND RECOMMENDATIONS
Working conditions are an important issue, so it should be taken into account when
designing a workspace, thereby, the worker will feel more comfortable and secure and will result
in higher productivity, lower absenteeism, fewer accidents, lower turnover, etc. To achieve this it is
necessary to design each station or place of work according to the needs of the population that
will occupy this space, this implies knowing the dimensions of the population, if not known, it can
hardly meet the target, however when known, can have an assurance that the highest percentage
of people who use the work area, will have no problems in terms of size and awkward postures.
By creating a product would be recommended to be used without problem by the largest
number of users. The reality is that many products do not have the ability to adapt to 100% of
users. For this you can follow two paths, the first would make products of various sizes in such a
way that takes the opportunity to choose the one that best suits the needs of the user, the other
would be to create products that are adjustable over a range measures, making it necessary to
know the cost-benefits so that decision making is correct. The selection of some of the
alternatives mentioned above would be facilitated if known anthropometric dimensions of the
population that is expected to address. From the above highlights the importance of the results of
this research.
