 Practical No 13 -  Estimate the cost of the project using COCMOII approach for assign project.


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. It was proposed by Barry Boehm in 1981 and is based on the study of 63 projects, which makes it one of the best-documented models.

The key parameters which define the quality of any software products, which are also an outcome of the Cocomo are primarily Effort & Schedule:

  • Effort: Amount of labor that will be required to complete a task. It is measured in person-months units.
  • Schedule: Simply means the amount of time required for the completion of the job, which is, of course, proportional to the effort put in. It is measured in the units of time such as weeks, months.
There are three types of COCOMOII model 

COCOMO consists of a hierarchy of three increasingly detailed and accurate forms. Any of the three forms can be adopted according to our requirements. These are types of COCOMO model:

  1. Basic COCOMO Model
  2. Intermediate COCOMO Model
  3. Detailed COCOMO Model

The first level, Basic COCOMO can be used for quick and slightly rough calculations of Software Costs. Its accuracy is somewhat restricted due to the absence of sufficient factor considerations.

Intermediate COCOMO takes these Cost Drivers into account and Detailed COCOMO additionally accounts for the influence of individual project phases, i.e in case of Detailed it accounts for both these cost drivers and also calculations are performed phase-wise henceforth producing a more accurate result. 


Result: Hence,We have calculated cost of bank management system using COCOMOII.

 Develop a activity diagram to represent a flow from one activity to anotyher for software develpment Activity diagram for Bank management system Activity diagram is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system. The control flow is drawn from one operation to another. This flow can be sequential, branched, or concurrent. Activity diagrams deal with all type of flow control by using different elements such as fork, join, etc.i t captures the dynamic behavior of the system. The purpose of an activity diagram can be described as − Draw the activity flow of a system. Describe the sequence from one activity to another. Describe the parallel, branched and concurrent flow of the system. Result - Hence,We have developed activity diagram to represent the flow of one activity to another for bank management system.

 Develop a data dlow diagram using dfd ,division table & ER diagram Data Flow Diagrams  are used to represent the flow of data as well as the processes and functions involved to store, manipulate, and distribute data among various components of the system and between the system and the environment of the system by a specific set of graphical representations. It also depicts the logical flow of information in a system and appropriately defines and determines the physical requirements for the construction of the system. The key features of a Data Flow Diagram involve simplicity of notation as well as generation of a clear overview of the manual and automated requirements of the system. Level 0 DFD : This level is also known as Context Level DFD. At this level, only the interacting inputs and outputs with a system are described. The DFD of this level is shown in the diagram Level 1 DFD : At this level, more detailed information is given about the processing of the ATM system....

Bank Management System Problem Statement The bank management system is an application for maintaining a persons account in a bank.The system provides the access to the customer to create an account deposit and withdraw his/her money anytime in his bank account using bank management system.Bank management system also allows its user to check their account report.The software is easy to use, and makes banking simple both for the bank and customer. Introduction The main purpose of bank management system is to provide an interface to the user  so one can easily deposit or withdraw cash or create a bank account.Bank management system solves financial application of a customer i...
