What is Cocomo 2 model?
COCOMO-II is the revised version of the original Cocomo (Constructive Cost Model) and is developed at University of Southern California. It is the model that allows one to estimate the cost, effort and schedule when planning a new software development activity.
What is the effective use of the Cocomo model?
Cocomo (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code. It is a procedural cost estimate model for software projects and is often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time, and quality.
Why is Cocomo important?
Detailed COCOMO incorporates all qualities of the standard version with an assessment of the cost driver’s effect on each method of the software engineering process. Advantages : It works on historical data and provides more accurate details. Easy to implement with various factors.
How many Cocomo models are there?
three
Types of COCOMO Models. COCOMO consists of a hierarchy of three increasingly detailed and accurate forms. Any of the three forms can be adapted according to our requirements.
How is COCOMO different from COCOMO 2?
It is also called as Basic COCOMO….Difference between COCOMO 1 and COCOMO 2:
| COCOMO I | COCOMO II |
|---|---|
| It provides estimates of effort and schedule. | It provides estimates that represent one standard deviation around the most likely estimate. |
| This model is based upon the linear reuse formula. | This model is based upon the non linear reuse formula |
How is function Point metric advantageous over LOC metric?
LOC is used for calculating and comparing the productivity of programmers. In general, people prefer the functional size of software indicated as Function Point for one very important reason, i.e, the size expressed using the Function point metric stays constant in any case and whichever language or languages are used.
What is the full form of COCOMO?
The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W. Boehm. The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II).
Which of the following is a disadvantage of COCOMO?
The disadvantages of COCOMO include: ® It ignores requirements volatility (but an organization may add this as an extra adjustment factor in computing EAF). ® It ignores documentation and other requirements. ® It ignores customer attributes—skill, cooperation, knowledge, and responsiveness.
Why is COCOMO important in project management?
Advantages of COCOMO estimating model are: – Accounts for various factors that affect cost of the project. – Works on historical data and hence is more predictable and accurate. – The drivers are very helpful to understand the impact on the different factors that affect the project costs.
What is complete COCOMO?
COCOMO or Constructive Cost Estimation Model is a model that estimates the effort and time taken to complete the model based on the size of the source code. It includes 15 multiplying factors from different attributes of the project, and finally calculates time and effort using this information.
Does COCOMO II replace traditional Cocomo?
Does COCOMO II replace traditional COCOMO? You should use COCOMO II for most of your new projects. COCOMO 81 is still the best approach for some software projects.
Which COCOMO II sub model assumes that systems are created?
| Q. | Which model assumes that systems are created from reusable components, scripting or database programming? |
|---|---|
| C. | a reuse model |
| D. | an early design model |
| Answer» a. an application-composition model | |
| Explanation: it is designed to make estimates of prototype development. |
What are the advantages of function point metrics?
Additional function point analysis benefits are the ability to assess the size of an application and to evaluate its ability to meet business or user requirements. It also serves as a productivity solution for evaluating the work completed by your team based on defined units.
Which one is not a category of COCOMO II?
| Q. | Which one is not a Category of COCOMO-II?( |
|---|---|
| B. | Infrastructure Sector |
| C. | Requirement Sector |
| D. | System Integration |
| Answer» c. Requirement Sector |
Where is cost in Cocomo MOdel?
Calculation. In COCOMO, the general calculation steps of COCOMO-based cost estimation are the following: Get an initial estimate of the development effort from evaluation of thousands of delivered lines of source code (KDLOC). Determine a set of 15 cost factors from various attributes of the project.
When was COCOMO made?
History. The constructive cost model was developed by Barry W. Boehm in the late 1970s and published in Boehm’s 1981 book Software Engineering Economics as a model for estimating effort, cost, and schedule for software projects.
