This paper emphasizes total self-development of the individual for improved motivation and organization management. It builds on Maslow's hierarchy of needs theory to examine motivational levels for four levels of engineering staff at a public construction agency. The researchers studied these engineering groups qualitatively through interviews and quantitatively using a questionnaire. Using a holistic approach, this study focused on 15 parameters from Maslow's five essential needs-the physical, safety, social, esteem, and selfactualization levels. Considerable emphasis was placed on the development of Maslow's principle of ''self-actualization.'' This difficult-to-grasp concept, as Maslow reported, is a prerequisite for enlightened management. The researchers analyzed engineers' perceptions regarding the fulfillment of need parameters and measured their perception of the importance of those parameters. Among specific findings were that junior project engineers had higher scores on self-actualization than senior engineers. Findings showed that changes are desirable for satisfying meaningfulness of tasks, increasing self-sufficiency in doing the job, and improving individuality and sense of mission of employees. The application of the findings based on Maslow's model directly benefits the agency studied and other organizations in development programs. It also helps in increasing morale. BACKGROUND General Early psychologists, belonging to Freud's school, studied mentally ill people to learn about human nature and its deficiencies. Psychological principles were primarily developed by subjective interpretation of diseases and neuroses. Their theories also relied on methods such as interpretation of dreams to expand knowledge of the human inner self. The theories placed major motivational emphasis on deep urges and inner drives. Second-generation psychologists belonged to the Behaviorism school led by John Watson (Globe 1970). This group used strictly ''scientific'' principles. Their theory established an approach based on external, environmental influences. Behaviorists put great stress on the associative or stimulus-response learning as the major explanation for human behavior, made through assumptions such as that man is flexible, malleable, and a passive victim of his environment.
