A software company has to develop a smart meter that, along with recording the electric consumption information, also provides services like monitoring consumption behavior, automatic billing, etc. The development team has to build the software that is strongly coupled with the hardware of the smart meter. The company applies COCOMO model for calculating the effort to develop the system.
The values for the constants in the COCOMO model for the different types of the project are as follows:
• Organic project: a = 2.4, b = 1.05
• Semi-organic project: a = 3.0, b = 1.12
• Embedded project: a = 3.6, b = 1.20
