The Basic COMO 81: Constructive Cost Model

A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been

The cost, team size and LOC are measured on the bases of COCOMO model. It is a constructive cost mode. Effort of the project is calculated by the help of algorithm models. One of these models which are widely used is COCOMO model. For the cost estimation of any project, COCOMO (constructive cost model) is used. This model was developed by Boehm in 1981. There are three versions of the COCOMO which are listed below:

With the correct use of Software Development Lifecycle principles and systems analysis tools they can offer significant savings in procurement and maintenance. The biggest motivation for using COTS components is that they will reduce overall system development costs and involve less development time because the components can be bought instead of being developed from scratch. This could prove to be useful for software development because of the ever increasing costs (Wikipedia, 2006).

In current era use of computers and machines are become vital in daily life. To operate these machines, we need to give them instruction of doing some work in specific format which is called software. So, when a problem arises or identified and one want a solution by using machines, need of new software arise. And thus, a software development life cycle starts. To make this life cycle more efficient and accurate, different SDLC model and software development modeling techniques exist. Here in this research paper we will discuss software modeling techniques. The term “model” is derived from the Latin word modulus, which means pattern, measure, and rule. While a modeling language is any artificial

Describe the six main stages of the software development life cycle and for each, add an example of the activities that would be carried out in relation to the development of the calculator software.

Answer: to answer this question very important to see the all four important and basic steps software cost estimation as followed:-

Base on the analysis the reference, the general consensus in the research is that this enterprise project fell into the most basic traps of software development, from poor planning to bad communications throughout the lifecycle of the project. Our team will focus on the following aspects including scope, human resource, procurement, unrealistic scheduling, contracting and contract management, program management and enterprise architecture, the report will analyze each topic and make corresponding recommendation to improve the practice.

For years companies have turned to IT (Information Technology) to make things easier and reduce the waste of paper and human computers. When companies find themselves regularly maintaining and upgrading their software is there room for Lean in software development? With business requirements perpetually changing can a business get to the place where the system is good enough? Cost cutbacks, faster time-to-market, improved products and differentiated services are now the essential pillars in managing any software development process. The shift has been to move away from the customary Systems Development Life Cycle (SDLC) approach to newer standards that provide higher certainty and decreased risk by ensuring that business deadlines are met. (Pillai, A., Pundir, A., & Ganapathy, L., 2012, p. 107).

Unlike conventional forms of financial management, cost management has a backbone effect in any kind of project management as not only does it ensures efficiency in terms of costs, but also efficiency in terms of time and output. The aim to incorporate cost management in organizational operations especially when planning outputs or evaluating viability of a project, cost management helps giving out result oriented indicators that help in decision making that can reduce the level of risk of misjudgement (Richman, 2002). That said, cost management is based on a lot of assumptions, presumptions and fluctuating factors that may implicate the indicators given out by existing cost schedules. This calls for cost schedules to be flexible and keep enough room to accommodate any instability or unforeseen changes and also calls for making certain assumptions so that variables that can fluctuate at a high rate can be stabilized when making calculations.

Choosing a proper method for software design is completely depended upon the requirements and end products of the company. These requirements and goals might change in the process of development of software depending upon the decisions of stakeholders, developers and system analysts.

Please answer all questions, meeting the minimum word count. Do not copy and paste anything, all words need to be typed by your own fingers.

Adjusted engineering hours: the number of hours required to develop a project of average project complexity, based on the adjustment method, which is based on a multiple regression model

In conclusion, ABC stands out by breaking down the costs into a very detailed level. This information will give management a very clear picture of which processes come with high costs but little value and how to improve the process or to eliminate the process entirely. This method is suitable for use when there is high overhead, complex product and in very competitive market.

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.
