Constructive Cost Model II Metrics for Estimating Cost of Indigenous Software

Abstract

There is growing concern over the frequent cases of cost overruns, and underestimation in software cost, especially, indigenous software products. This has a lot to do with the choice of Cost-estimation tools, techniques and models deployed. Constructive Cost Model (COCOMO) II model has been adjudged as the most reliable and accurate. However, the existing cost drivers/variables of this model (COCOMO II) do not capture fully the uniqueness of Nigeria's computing environment. This paper has highlighted the strengths and weaknesses of COCOMO II considering the hierarchy of COCOMO. A new algorithm was proposed to effectively enhance the cost estimation effort of indigenous software in Nigeria Njoku A. Obilor et al.

Prediction based cost estimation technique in agile development

“…These techniques are Scrum methodology, function point, expert analysis, and Delphi technique as shown in Table 1. These all techniques have several limitations to measure the accurate cost and time for agile software development with change requests from the client [8][9][10][11]. Table 1 is describing the cost estimation techniques and adopted features for suggesting a new estimation technique.…”

“…In the last paper, we had done a comparison with the existing techniques and in a survey, we got responses from the participants regarding the estimation technique features, reliability, and accuracy to estimate efforts. However, in the extended version, we have visited software industries to apply the cost estimation technique to projects [6][7][8]. The main difference between the previous version and the extended version is, lastly we had done a survey regarding the proposed estimation technique and done a comprehensive study with the existing estimation techniques but now we have applied the proposed estimation technique to projects and found outcomes [9,10].…”

PSO-GAScript: A Domain-specific Scripting Language for Meta-heuristics Algorithm

“…The PSO-GAScript has to be evaluated with regards to the easiness, conciseness and flexibility. Lines of Code (LOC), words of code (WOC) and characters of code (COC) have been widely used in the software development measurement model to estimate easiness of programming language, including in the COnstructive COst MOdel (COCOMO) [19]. This paper focused on the conciseness aspect as it is formulated from one of the easiness metrics namely COC while flexibility will be reported in the future publication.…”
