run without human intervention & no organization can
exist if it cannot serve peopleâs needs.

are hired, trained, compensated, motivated & maintained.

43. HRM Today
We must understand that corporations are not in the
business of human resource development. They are in their
own business, but human resource development is an
important tool which, unfortunately, is being used in a
limited sense. The corporate mission has not been attached
to it. Actually, human resources must become the business
of everyone in the organization.
- T. V. Rao
Equal access to all resources is forcing organisations to rely
on their people as the only source of competitive advantage
today
43
44. HRM Today âŚContd.
Human resource strategy involves a central philosophy of
the way the people in the organization would be managed
and the translation of this into human resource policies
and practices.
It requires human resource policies and practices to be
integrated so that they make a coherent whole and also
that this whole is integrated with the business or
organizational strategy.

45. HUMAN CAPITAL MANAGEMENT

49. Competitive Challenges Influencing HRM
Three competitive challenges that companies now
face will increase the importance of human resource
management practices:
1. The challenge of sustainability
2. The global challenge and
3. Technology challenge
50. The Sustainability Challenge
Traditionally, sustainability has been viewed as one
aspect of corporate social responsibility related to
the impact of the business on the environment.
However, we take a broader view of sustainability.
For our purposes, sustainability refers to the ability
of a company to survive and succeed in a dynamic
competitive environment. Company success is based
on how well the company meets the needs of its
stakeholders.
50
51. The Global Challenge
Companies are finding that to survive they must compete in
international markets as well as fend off foreign corporationsâ
attempts to gain ground in the United States. To meet these
challenges, U.S. businesses must develop global markets, use
their practices to improve global competitiveness and better
prepare employees for global assignments.
51
52. The Technology Challenge
The Internet has created a new business modelâe-
commerce, in which business transactions and relationships
can be conducted electronically. The Internet is a global
collection of computer networks that allow users to exchange
data and information.

54. Managing the Human Resource
Environment
Managing internal and external environmental factors allows
employees to make the greatest possible contribution to company
productivity and competitiveness. Creating a positive environment
for human resources involves:
o Linking HRM practices to the companyâs business objectives
âthat is, strategic human resource management.
o Ensuring that HRM practices comply with federal, state and
local laws.
o Designing work that motivates and satisfies the employee as
well as maximizes customer service, quality and productivity.
54
55. Acquiring and Preparing Human Resources âŚ
Contd.
This area of human resource management deals with:
o Identifying human resource requirementsâthat is, human
resource planning, recruiting employees, and selecting
employees.
o Training employees to have the skills needed to perform their
jobs.
Compensating Human Resources âŚContd.
This area of human resource management includes:
o Creating pay systems.
o Rewarding employee contributions.
o Providing employees with benefits.

o Measuring employeesâ performance.
o Preparing employees for future work roles and
identifying employeesâ work interests, goals, values and
other career issues.
o Creating an employment relationship and work
environment that benefits both the company and the
employee.
57. Strategic Role for HR
For HR to play a strategic role it must focus on the longer-term
implications of HR issues. How changing workforce
demographics and workforce shortages will affect the
organization and what means will be used to address the
shortages over time, are examples of the strategic role. A
strategic role for HR is important, but it requires a high level of
professional and business knowledge. The HR Perspective
shows that the transition to a strategic role is not without
difficulties.
57
58. Enhancing Or ganizational
Performance
Organizational performance can be seen in how
effectively the products or services of the
organization are delivered to customers. The
human resources in organisations are
designers, producers and deliverers of those
services. Therefore, one goal of HR
management is to establish activities that
contribute to superior organizational
performance. Only by doing so can HR
professionals justify the claim that they
contribute to the strategic success of
organisations.

64. EMOTIONAL INTELLIGENCE
⢠Emotional Intelligence (EQ)
â The extent to which people are self-aware, can
manage their emotions, can motivate themselves,
express empathy, and possess social skills
⢠Persons with high EQs may perform better on jobs
that require interaction and directing others.
⢠EQ can be developed and is not biologically based.
65. â˘The ability of an organization to perform depends on the
relationships of the people involved, which ultimately
relates to the degree of emotional intelligence of its
employees and leaders.
â˘Leaders possessing Emotional Intelligence will create an
effective work climate that will further develop emotional
intelligence at the subordinate level.
â˘The higher the level of a jobâs complexity and authority,
the greater the impact of high Emotional Intelligence.
66. â˘The ability of an organization to perform depends on the
relationships of the people involved, which ultimately
relates to the degree of emotional intelligence of its
employees and leaders.
â˘Egon Zehnder International analyzed 515 senior executives.
Those strong in EQ were more likely to succeed than those
who were strongest in relevant experience or IQ. EQ is a
stronger predictor of success than experience or high IQ.
Study included execâs from Latin America, Germany, Japan
with same results across cultures.

76. ESOP
⢠An employee stock ownership plan (ESOP) is a way in which
employees of a company can own a share of the company
they work for. There are different ways in which employees
can receive stocks and shares of their company. Employees
can receive them as a bonus, buy them directly from the
company, or receive them through an ESOP.
⢠In the United States, ESOPs are a very common form of
employee ownership. They have been growing in strength
since about 1974.
⢠The main purpose of an ESOP is to reward and motivate
employees. They are also used to provide a market for
departing owners of successful companies. In most cases,
an ESOP is given to an employee, rather than purchased by
an employee.
77. ⢠An ESOP is similar to a profit-sharing plan.
⢠A trust fund,
⢠contributes either new shares of its own stocks or cash to buy
existing shares.
⢠Another version of the ESOP borrows money in order to buy
existing or new shares.
⢠repay the loan.
⢠Shares in the trust are generally allocated to individual employee
accounts.
⢠When employees leave the company, they receives their share
options, and the company must be able to buy back these options.
They must buy them back at their full market value. In private
companies, employees are able to vote their shares on major issues
such as relocation or closure. In public companies, employees can
vote on all issues.
78. FLEXI-TIME
It is a programme that allows flexible entering and leaving
times for employees.

⢠Sigma is a measure of âgoodness: the capability of a
process to produce perfect work.
⢠A âdefectâ is any mistake that results in customer
dissatisfaction.
⢠Sigma indicates how often defects are likely to occur.
⢠The higher the sigma level, the lower the defect rate.
⢠The lower the defect rate, the higher the quality.
91. ⢠A metric that indicates how well a process is performing.
⢠Measures the capability of the process to perform defect-free
work.
⢠Also known as âzâ, it is based on standard deviation for
continuous data.
⢠For discrete data it is calculated from DPMO.
92. SIX SIGMA METHOD
⢠Six sigma method is a TQM process that uses process
capability analysis as a means of measuring progress.
⢠The smaller the standard deviation, the lesser the
deviation of the product characteristic from its mean value.
If the process has a normal distribution, the upper and
lower specification limits are +/- 6 sigma from the mean u.
The non-conformance is 2ppb and the process capability Cp
is 2.0(1.33 Cp is de facto standard.)
⢠A normal process with mean shifted +/-1.5 sigma from the
target value desired has non-conformance of 3.4ppm and
process capability index Cpk= 1.5, with 1.0 being the de
facto standard.
