Organizational culture 
refers to a system of shared meaning held by members that
distinguishes the organization from other organizations. It  describes how employees
perceive the characteristics of an organization’s culture, not whether or not they like
those characteristics.   The dominant culture is the overall organizational culture as
expressed by the core values held by the majority of the organization's members.
Subsets of the overall culture, or subcultures, tend to develop in larger organizations
to reflect the common problems, situations, or experiences that are unique to members
of certain departments or geographical areas. 
A  strong culture exists when an organization's core values are both intensely held and
widely shared.  Strong culture achieves the same ends as formalization, but without
the need for written documentation.  They are two means to the same ends:
predictability, orderliness, and consistency. Since strong organizational culture
increases behavioral consistency, strong culture can act as a substitute for
formalization.
There are seven key characteristics of organization values. They are
    1. Innovation and risk taking - the degree to which employees are encouraged to
        be innovative and take risks.
    2. Attention to detail - the degree to which employees are expected to exhibit
        precision, analysis, and attention to detail.
    3. Outcome orientation - the degree to which management focuses on results or
        outcomes rather than on the techniques and processes used to achieve those
        outcomes.
    4. People orientation - the degree to which management decisions take into
        consideration the effect of outcomes on people within the organization.
    5. Team orientation - the degree to which work activities are organized around
        teams rather than individuals.
    6. Aggressiveness - the degree to which people are aggressive and competitive
        rather than easygoing.
    7. Stability - the degree to which organizational activities emphasize maintaining
        the status quo in contrast to growth. 
There are five basic functions of culture:
     Defines boundaries - culture creates distinctions between one organization and
        another.
     Identity - culture conveys a sense of identity for its members.
     Commitment - culture generates commitment to something that is larger than
        one's own self-interest.
     Social stability - culture is the social glue that helps hold the organization
        together by providing appropriate standards for socially acceptable employee
        behavior.
     Control mechanism - culture serves as a sense-making and control mechanism
        that guides and shapes the attitudes and behavior of employees. 
There are some potentially dysfunctional aspects of culture, especially a strong one,
on an organization’s effectiveness that need to be noted. They are
    Institutionalization: When an organization undergoes institutionalization and
       becomes institutionalized, that is it is valued for itself and not for the goods or
       services it produces, it takes on a life of its own. Behaviors and habits that
       should be questioned and analyzed become taken for granted, which can stifle
       innovation and make maintaining the organization’s culture an end in itself.
    Barriers to change: Culture is a liability when the shared values are not in
       agreement with those that further the organization’s effectiveness.
    Barriers to diversity: Hiring new employees who differ from the majority in
       race, age, gender, disability, or other characteristics creates a paradox. Since 
       diverse behaviors and unique strengths are likely to diminish as people attempt
       to assimilate, strong cultures can become liabilities when they effectively
       eliminate these advantages.   A strong culture that condones prejudice, supports
       bias, or becomes insensitive to people who are different can even undermine
       formal corporate diversity policies.
    Barriers to acquisitions and mergers:  All things being equal, whether the
       acquisition actually works seems to have more to do with how well the two
       organizations’ cultures match up.
The ultimate source of an organization's culture is its founders who have a vision of
what the organization should be.  A new organization's small size facilitates the
founder’s imposition of his or her vision on all organizational members.  Founders
create culture in three ways:
          1.
          o   Employee selection - founders hire and keep only those employees who
              think and feel the same way the founders do.
          o Socialization - founders indoctrinate and socialize their employees
              toward the founders’ way of thinking and feeling.
          o Modeling - the founder acts as a role model and encourages employees
              to identify with him or her and to internalize the founder’s beliefs,
              values, and assumptions. Any organizational success is attributed to the
              founder’s vision, attitudes, and behavior. 
The selection process of an organization needs to identify and hire employees with
relevant knowledge, skills, and abilities. One of the more critical facets of this process
is ensuring that those selected have values that are consistent with those of the
organization.  The verbal messages and actions of top management also establish
norms of behavior throughout the organization.
Socialization is the process by which new employees adapt to the organization culture.
There are three stages in the initial socialization of an employee in an organization.
    Prearrival stage: This encompasses all the learning that occurs before a new
      member joins the organization. Each individual arrives with his or her own
       unique set of values, attitudes, and expectations both surrounding the work and
       the organization. That knowledge, combined with how proactive their
       personality is, are the two critical predictors of how well the new employees
       will adjust to the new culture. The perception of being able to “fit in” is critical
       in the hiring process.
      Encounter stage: This is when the new employee sees what the organization is
       really like and confronts the possibility that expectations and reality may
       diverge. If the employee's expectations prove to be reasonably accurate, the
       encounter stage merely provides a reaffirmation of the perceptions gained
       earlier. But when expectations and reality differ, new employees must undergo
       socialization that will detach them from their previous assumptions and replace
       them with another set the organization deems desirable.
      Metamorphosis stage:  In this final stage, relatively long-lasting changes take
       place as the employee has adjusted to the work itself and internalized the work
       group’s values and norms. Successful metamorphosis should have a positive
       effect on new employee productivity, organizational commitment, and turnover
       as the employee would have internalized the norms of the organization and
       their work group.
There are various options for socializations.
     Formal versus Informal:  Formal programs segregate the employees from
       ongoing work and differentiate them in some way as a newcomer.  Informal
       programs simply put the new employee to work.
     Individual versus Collective: Socialization can occur on an individual or group
       basis.
     Fixed versus Variable: refers to the time scheduled when newcomers make the
       transition from outsider to insider.  A fixed schedule establishes standardized
       stages of transition, such as probationary periods.  Variable schedules give no
       advance notice of transition timetables.
     Serial versus Random:  Serial programs use role models to train and encourage
       the newcomer, such as in apprenticeship programs.  In random programs, role
       models are deliberately withheld and employees must learn to figure things out
       on their own.
     Investiture versus Divestiture:  Investiture socialization assumes and confirms that
       newcomers have the necessary qualities and qualifications for success. 
       Divestiture programs try to strip away certain characteristics of the recruits to
       reshape them into the proper role.
Setting a positive ethical organizational climate starts at the top of the organization.
When top management emphasizes strong ethical values, supervisors are more likely
to practice ethical leadership. This positive ethical attitude transfers down to line
employees, who show lower levels of deviant behavior and higher levels of
cooperation and assistance. Employees whose ethical values are similar to those of
their department are more likely to be promoted, so we can think of ethical culture as
flowing from the bottom up as well.
