EXPLAIN THE COCOMO MODEL AND THE PURPOSE OF ITS USE SOFTWARE
Since its publication in, the COCOMO model presented in Software Engineering Economics(SEE) by Barry W. Users do further testing in uat before we get signoff. Cocomo (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code. Differentiate between basic COCOMO model and intermediate COCOMO model. If end user or any stakeholder rejects a story in sprint review, should we reject the sprint even though we marked all sprint items as done? We showcase our sprint work in sprint review from uat environment to end users. This means that PO has to test story in test environment like qa and if they accept we can mark story as done. A software company needs to develop a project that is estimated as 1000 function points and is planning to use JAVA as the programming language whose. While product owner cannot accept a story, we cannot mark it done. For example, a time stream of costs and resurfacing projects for one pavement section is shown in Figure 5-11.
We maintain various environments like dev, qa, uat, prod, etc. Using a life cycle model which predicts the economic life of highway pavement on the basis of the effects of traffic and other factors, an optimal schedule for rehabilitation can be developed. Product owner should accept a story is one of acceptance criteria i.e. Should we estimate story points for post production defects to be included in next sprint? Should we include story points for post production in velocity? If we include story points of post production defect in velocity of sprint then aren't we taking credit twice for the same work? How should we manage defects? So when should we do estimations for stories (sprint planning or back log refinement), when should we do it? IF we do story estimation in sprint planning then what is point of backlog grooming? Why do we need 2 ceremonies? If we leave all estimation for sprint planning than backlog will never have estimates of stories before sprint planning?

It should be used if there’s high availability of designers for modeling and the budget is high enough to afford their cost along with the cost of automated code generating tools. When is backlog refinement conducted? We do it before starting of next sprint but my confusion is in sprint planning we pick stories and do estimation as well. When to use RAD model: RAD should be used when there is a need to create a system that can be modularized in 2-3 months of time.
