This study explores the key success factors for business success of companies in the
Namibian Tertiary Industry. There is a dearth of scholarly research on key success factors for
business success from a developing country perspective. Considering the differing operating
contexts between the developed and developing countries, exploring the key success factors
from a developing country viewpoint is warranted. The study employed a sequential Mixed
Methods Research Approach, which begins with Interpretivistic research in the first phase
and then progresses to Positivistic research in the final phase. Multiple and triangulated data
sources, such as interviews from 54 participants, archival document analysis and personal
observations were used to capture and socially construct key success factors for business
success. A survey to establish the extent to which the identified success factors are observed
and entrenched in Namibian companies is to be conducted in the latter phase. During the
Interpretivistic research phase, the study used Grounded Theory techniques in collecting and
analysing data. The study preliminary findings suggest that people in the organisation,
especially activities and practices relating to continuing employee training and development,
implementation of company-wide organisational communication, using Unions as
instruments for meaningful employer-employee engagement, establishing a common
organisational value system that appeals to all employees and senior management
consistently practising a high set of personal values, are key success factors for business
success. In view of the prevalent cultural diversities and differing educational levels in
developing countries, managerial patience also emerged as a key success factor that managers
should be aware of and practice.
