Productivity
The conceptProductivity, reflects that so or the resources are
used to create exits to other processes or to generate finished
products (outputs). More specifically, this measures the
relation between outputs and one or insumos (inputs).
The labor productivity, presents/displays outputs per
toiled hours. It is the measurement more commonly used.
Nevertheless the labor productivity has been criticized being
single to be a measurable part that does not consider the effects of
others inputs.
Recently a more comprehensive measurement talks about a
total factor of productivity. This measurement includes the
contributions of the work, capital, materials and energy.
The Formula
Productivity = insumos products/(within a period of
time considering the quality) the formula indicates that the
productivity can be improved:
- Increasing products with such insumos,
- Diminishing the insumos, but maintaining products
such, or
- Increasing products and diminishing the insumos to
change the relation favorably.
The companies use diverse classes of insumos as they are
the work, the resources and the capital. The greater opportunity
to increase the productivity is specially in the own work of knowledge
and in the administration.
Importance Of measuring the Productivity
The measurement of the productivity allows to
compare under a same measurement the development of companies, trains
and nations.
Why the productivity is important? The answer is
that directly it influences in many other essential factors. The
high productivity means stop real entrance for the worker, the company
high utilities, discharge investment in investigation and development
and more attention to the problems of the medio.ambiente.
In industries it nails, this means minors costs and a
participation discharge in the international market. And for the
nations this means standard stops of life, less inflation better
balance of payments and a more hard currency.
Many companies, specially those that try the international
competition are very conscious about their slow productivity and
highly are interested in improving their efforts. The companies
use a great variety of directions to improve the productivity.
The three but important directions are:
Technological, which focuses to changes
greater in equipment and technological processes; administrative, which is oriented to
define the strategic mission more clearly, to change the basic
structure, and to apply the techniques of administration of
operations, and conductual which
focuses the worker, to increase its motivation and participation.
Measurement of the productivity in the administrative
employees
The typical form to measure the productivity is
the coefficient between in number of production units (cars,
refrigerators, computers, etc.) and the number of employees who
appear in the list (or worked hours of paid administrative employees).
This measures the competitive level of a company or an industry.
This coefficient allows us in addition to identify the location
of any deficiency in the productivity of the administrative employees
and its causes. Since added to the relation between production
and total use of office personnel, generally also we can measure the
coefficient between the total production and the dowry of
administrative employees. This measurement can indicate
whichever improvement can be expected and compare an organization with
the competition. This measurement indicates to us if a company
or an industry is improving the productivity of its administrative
force. The coefficient between the production and the use of
office personnel, also allows us to compare the past with the present
and establishing objectives for the future. In a company that
grows quickly, the number of administrative employees generally
increases in direct proportion to the production, whereas other things
as the technology and the equipment stay equal.
But the office use would have to increase in form slower
than the production and the sales, perhaps single half of express.
If it increases as fast as the production or the sales, and
worse still, if it increases to more express the company runs the risk
of becoming noncompetitive.
Other three measurements of the productivity of the office
personnel exist that can be compared with the vital signs, first it is
the time that takes to remove to a new product or service from the
development to its launching to the market. Second it is related
to the amount of new products and successful services that have been
offered to the consumers in a given time, specially comparing them
with the national or international competition.
Thirdly it is the number of support people and specially,
of necessary levels of administration for a given production.
Standards of Accomplishment
An important element of the productivity
constitutes the accomplishment standards. These serve to
regulate the conduct and the form to work, also establishes what it is
expected of each position within an organization. They establish
the level of productivity accepted by a person or a group.
Nevertheless this is not sufficient. Some made studies,
indicate that the cohesion of the group determines the form in that
they will extend and which of these standards will be applied.
In other words, the planning and the organization will be of
little utility if they cannot influence so that the groups accept the
standards.
The cohesion is defined as the sum of the attraction of
all the members towards the group. People can be attracted for
many reasons, by estatus of the group, reason why the group does,
reason why the members obtain when acceding to other sources of wished
resources, by the attraction of each one of their members, by the
sense of property or any other reason.
When one compares the time and the resources used in a
work with which one takes place, the productivity is being determined.
And when the work improves, that is to say, when more amount or
better quality takes place such using the same time and resources, an
increase in the productivity has been obtained.
The productivity is a measurement that sample that so
producing is. It indicates as any thing develops.
Increasing the Productivity
The forms are several in which the productivity
can be increased:
To work more intelligently, and intelligence is obtained
with money, time and effort to increase the knowledge and to eliminate
the ignorance.
To find one better tool to make the work easiest, with
smaller effort or to produce more.
Modifying the work technique to facilitate it, to improve
the quality or to increase the amount.
Some Techniques To improve the Productivity
Investigation of operations,
models that represent of a logical way the reality of a problem, I put
and their restrictions to obtain them, variable which they affect the
problem, quantifications of to where it is possible to be arrived and
probabilities, are oriented to determine the optimal combination of
resources to obtain a wished intention.
Planning and control of inventories.
With its formula: Qe = û 2DS/H. Where: Qe = economic Amount of order D = annual Demand S = Costs of ordering H = Cost of maintaining existence by article per year û = square Root
Systems of inventories Just on time, other names of this method are inventory zero and
production without existence. So that it works certain
requirements must be fulfilled:
- The quality of the pieces must be very high, the quality
of the pieces, a defective piece can stop the assembly line,
- They must exist reliable relations and an ample
cooperation with the suppliers,
- Ideally the suppliers must be located near the
company, existing safe transportation.
Improvement of the logistics
Reingenierías and simplifications of the work
Engineering of the Value, consists of analyzing the operation of the product or
service, considering the value of each operation and of trying to
improve that operation being treated to maintain under the cost of
each step or starts off. The specific steps are:
- To divide to the product in parts and operations,
- To identify the costs for each part and
operation,
- To identify the value relative of the contribution
of each part to the final part,
- To find a new approach for those games that seem
to have a high cost and under value.
Circles of quality, equipment of continuous improvement.
CorolarioProductivity is an evaluation of the efficiency of
the process of transformation of the organization to turn the insumos
products. A greater productivity comes from three primary
sources: Technology, administrative ability, and human effort.
A deterioration of anyone of these sources has adverse effects
in the productivity.
The definition of goals or standards is not sufficient.
It is required to put greater attention in the psycho-social
system and to create an atmosphere of greater participation of the
employees which can bring important benefits in productivity terms.
In this sense, the Empower understood like creating an atmosphere in which the
employees and all the levels feel that they have a real influence on
the standards of quality, service, and efficiency of the business
within their areas of responsibility, constitutes a
fundamental tool. One is not to leave the power or to lose the
margin it maneuvers. On the contrary, empowerment, does not divide the piece of
the pie in small pieces. This it promotes to cook a pie greater
than it feeds each one in its table more rich and healthfully.
