Modeling Principles of Decision Support Systems

The Interactions of Man-Power

The formal sector uses standard methods and generally employs technicians often considered as focal points for each job category. These technicians usually have a regular contract of employment compared to those in the informal sector. Most often, the technicians are very few and responsible for contacting the temporary workers in the informal sector, who are essentially jobbers, and whom their availability and the competence are not always cannot be ascertained. It is the responsibility of the focal points of the formal sector to respect the general work schedule, involving several jobbers from the informal sector with varying skills and uncertain work pattern or availability. This dependence on jobbers shows the importance and risk of delivery construction projects using the informal sector’s workforce. This dependence becomes more complex as each team leader (i.e. from focal points) have to manage many other team leaders from the informal sector with most on non-permanent contracts. For example, Figure 1 shows how a bricklaying team leader Mi manages others bricklayers m_jl from the informal sector.
