Q. Explain the relationship between Productivity and difficulty?

Productivity refers to metrics as well as measures of output from production processes per unit of input. Productivity P perhaps conceived of as a metrics of the technical or engineering efficiency of production. In software project planning efficiency is defined as the number of lines of code developed per person-month Difficulty The ratio (K/t_d2) where K is software development cost and t_d is peak development time is called difficulty and denoted by D which is measured in person/year.

D= (K/t_d2)

The relationship demonstrates that a project is more difficult to develop when the manpower demand is high or when the time schedule is short. Putnam has experiential that productivity is proportional to the difficulty Pa D_b The average productivity may be defined as P=Lines of code produced/Cumulative manpower used to produce code =S/E Where S is the lines of code produced as well as E is cumulative manpower used from t=0 to td (inception of the project to the delivery time).
