Introduction
The department of human resource (HR) is extremely important in the proper functioning of any given organization. This is because it controls and manages the most important resource: the human resource.
It is usually a tremendous challenge to HR managers to coordinate the activities of all employees in the running of the organization as one unit. This is because there are changes every now and then in terms of organization’s activities and policies and introduction of new employees.
The HR managers have to take up this role of orienting new employees to the organization for them to fit in effectively and the role of orienting the existing employees to new changes in the organization.
In doing this, the HR managers need to ensure that there is effective communication which will bring about cooperation and coordination among the employees and in relation to their superiors. Proper training which requires, patience as one deals with a diverse workforce is vital in facilitating individual adaptation to the new environment or the new changes (Christensen, 2006).
Validity
Validity is the level to which a given study may answer scientifically the question/s it is set to answer by relating to the real word. The conclusions made after the end of a study should be connected to the study design. There are various types of validity. They include among others external, internal and construct validities.
External validity refers generalized conclusions. It is related to the actual real world studying whether for example a sample selected to study a given population is representative of that population. Internal validity on the other hand involves the cause relationship between the variables in a given study.
It involves studying the how dependent variables may be influenced by independent variables. Finally construct validity refers to concepts of a given constructs show or measure what they are said to be doing. It is measuring the strength of research tools like for instance questionnaires.
These validities although different as has been described are all integrated in a research project. They should all conform to the research theory as this the central aspect of the research. In a research project, for instance you can not only concentrate on the external environment without considering the internal environment and in both you have to ensure that the tools used do measure up to attaining plausible results.
A major threat to external validity is determining whether the correct sample to represent the entire population has been selected. There could be biases also in selecting a representative sample of a population. If incorrect or non-representative sample is selected, then the whole research project may be jeopardized.
Construct validity may give wrong conclusions regarding a research tool. If for instance interviewing is carried out in place, where questionnaires were required could lead to problems in data collection. These among many other problems should be carefully addressed for a research project to be successful (Christensen, 2006).
Validity issues are vital in any research. For instance in studying the role of human resource management in facilitating individual adaptation of the employees, one has to ensure that a representative of data of both the managers and the employees is collected. You also have to determine which construct tool is the most effective in gathering of information as noted by Christensen (2006).
