It should be carefully noted that an effort 100 PM does not mean that 100 person should work for one month nor does it mean that one person should be employed 100 months, but it denotes the area under person-month curve. The effort estimation is expressed in units of person- months(PM). So estimation of Development Time Basic COCOMO: Person-month curve

Tdev is estimated time to develop the software, expressed in months.Ī1,a2,b1,b2 are constant for each category of software products, Basic COCOMOīasic COCOMO applies the parameterized equation without much detailed consideration of project characteristics. It may vary according to organization by 10% to 20%. COCOMO consider 152 hours per person month.

He considered software size innovation deadline / constraint deadline and development environment and gave three modes which wereĬOCOMO model depends on two main equations:īased onMM- man month (MM)/ person month(PM)/ staff month is one month of efforts by one person. According to him, software cost estimation should be done through three stages.īoehm proposed that there can be three modes of software development project based on development complexity.
