Despite it may look simple, an estimation process is quite a challenging task (image by Luk Strak). Did the user require response time or throughput? According to COCOMO Complexity, the software effort is calculated based on predetermined coefficients based on complexity and, lines of code, for example, if we considered that we are using organic project type our calculation will be as follow: Effort Applied (E)= a*(KLOC)^b = 3.2 * (10) ^ 1.05 35 Person Months, Development Time (T) = c*(Effort Applied)^d = 2.5 * ( 35) ^ 0.38 9.7 Months, People required (P) = Effort Applied / Development Time = 35/9.7 +/- 3.6 Persons, Development Productivity = LOC/Effort Applied = 10,000/35 286 LOC/Person Month. If we assume that our EAF is 1.17 then the adjusted effort will equal to 35 * 1.17 41 Person Months. any suggestion would be much appreciated .. Development.

The volatility of the virtual machine environment, Application of software engineering methods, Identify inputs, outputs, file accesses and interfaces to external systems, Determine the functional complexity of each function, Calculate unadjusted FPs by summing weightings, Calculate Value Adjustment Factor for the software, Apply VAF to UFP to calculate adjusted FPs, COCOMO. In agile development, the product owner is tasked with prioritizing the backlog the ordered list of work that contains short descriptions of all desired features and fixes for a product.
