Chapter 5 Feasibility Analysis System Analysis Design

Investments in information technology have become crucial for firms to improve the quality of their products and services. Investment in information technology or information system has increased over a decade. They must view it as a tool to help them attain their strategic business objective.

Due to the limited resources and time, companies must wisely choose to invest in the projects that match their business and economic goals. Therefore, the feasibility study is an integral part during the planning phase of the system development life cycle SDLC. One of the feasibility factors that need to be assessed is economic feasibility.

Management can assess economic feasibility by doing the cost-benefit analysis, as well as using financial techniques, such as time value of money or break-even point analysis. In addition to the economic feasibility analysis, this paper will also look at some other feasibility factors, such as technical, operational, scheduling, legal and contractual, and political feasibility.

What is Feasibilty Study? A feasibility study, also known as feasibility analysis, is an analysis of the viability of an idea. The results of this analysis are used in making the decision whether to proceed with the project or not. This analytical tool used during the project planning phrase shows how a business would operate under a set of assumption, such as the technology used, the facilities and equipment, the capital needs, and other financial aspects.

The study is the first time in a project development process that show whether the project create a technical and economically feasible concept. As the study requires a strong financial and technical background, outside consultants conduct most studies. Matson A feasible project is one where the project could generate adequate amount of cash flow and profits, withstand the risks it will encounter, remain viable in the long-term and meet the goals of the business.

The venture can be a start-up of the new business, a purchase of the existing business, and expansion of the current business Hofstrand and Holz-Clause, Why Prepare Feasibility Study? There are many ideas that do not develop i nto business operation. Even though these ideas make it to the operational stage, most fail within the first six months.

Therefore, before investing in the proposed project, one must determine whether that IT projects can be economically viable and the investment advantages outweigh the risks involved Matson Also, many IT projects are quite expensive to conduct and it also involve unfamiliar risks. Moreover, there are numerous possible IT projects that firms could invest in.

If companies had unlimited resources and infinite time, all projects would be feasible Pressman However, in the real world business, there are problems of scarcity of both time and resources. Management is constantly faced with a wide array of possible investment alternatives and forced to choose one project over the others. Also, most projects must be developed within the time constraints and under the limited budget.

The feasibility study allows us to preview the potential outcome and to decide whether they should continue. Although the cost of conduct this study may seem high, there are relatively minor when compared with the total project cost. This small initial expenditure on feasibility study can help to prevent larger loss later.

Types of Project Investment. Chen classifies types of capital investment into three board areas, depending on their impact on cooperate profit:. Pure obligatory investments may not pass the profit tests, as it will reduce corporate profitability from prior-year levels; however, it could expand its scope to include profitable item to justify the investment.

Estimation is to figure out the approximate result which is usable even if input data may be incomplete or uncertain [1]. Estimating is the main part of feasibility analysis. Unexpected changes in any of these variables will impact an outcome of the project. Therefore, making good estimates of time and resources for a project is crucial. Underestimating project needs may cause the inadequacy of time, money, infrastructure, materials, or people to complete the project while overestimating needs can lead to reject of this adequate project, or postpone the project because it is too expensive.

According to the Article in developer. Knowing which of these three different estimates you can provide is crucial. Also, in many cases, we may be able to give more detailed estimates for some items rather than others.

For example, we may be able to provide a rough estimate of the infrastructure we need but only an order of magnitude estimate of the people and time needed.

Estimation Technique for new projects Order of magnitude estimates. Estimation Techniques familiar projects Rough or Fair estimates. There are several techniques for cost estimation, but the 2 basic approaches are top-down and bottom-up.

Using experts in both software development and the application domain to predict software costs. Economic Feasibility. Economic evaluation is a vital part of investment appraisal, dealing with factors that can be quantified, measured, and compared in monetary terms Chen The results of an economic evaluation are considered with other aspects to make the project investment decision as the proper investment appraisal helps to ensure that the right project is undertaken in a manner that gives it the best chances of success.

Project investments involve the expenditure of capital funds and other resources to generate future benefits, whether in the form of profits, cost savings, or social benefits. For an investment to be worthwhile, the future benefit should compare favorably with the prior expenditure of resources need to achieve them. To assess economic feasibility, management has to analyze costs and benefits associated with the proposed project.

The capital cost of a project affects the economic evaluation. Cost estimating is essentially an intuitive process that attempts to predict the final outcome of a future capital expenditure Chen Even though it seem impossible to come up with the exact number of costs and benefits for a particular project during this initial phase of the development process, one should spend the adequate of time in estimating the costs and benefits of the project for comparison with other alternatives.

However, in addition to these tangible costs, there are also some intangible costs, such as loss of goodwill, or operational inefficiency. One methodology for determining the costs of implementing and maintaining information technology is Total Cost of Ownership TCO.

It is a financial estimate designed to help consumers and enterprise managers assess direct and indirect costs. The tangible benefit, such as cost saving or increasing in revenue, would be easier to estimate while intangible benefits are harder to quantify. Time Value of Money. There are several economic evaluation methods available to assess an investment.

Even though, NPV approach and IRR approach will normally provide the same decision result, polls of industry indicate that the IRR is the number one economic evaluation decision method use by about two-thirds of industrial companies Chen This is due to the fact that some managers prefer a percentage rate of return more than the dollar amount from NPV. The concept of Time value of money is that a dollar today is worth more than a dollar available at a future date because a dollar today can be invested and earn a return.

Someone investing a sum of money today at a given interest rate for a given period of time would expect to have larger sum of money at the future date Baker and Powell As different projects may provide benefits at the different time in the future, all costs and benefits of the projects should be viewed in relation to their present value.

Present value is the value of a future cash stream discounted at the appropriate market interest rate, called discount rate. The present value of the future cash flow can be calculated using the following equation:. Adding the present values of each individual positive or negative cash flow based on the opportunity cost of capital.

In this case the present is taken as the time at which evaluation is carried out. Chen The discount rate at which the net present value of an investment is zero. Ross, Westerfield, and Jaffe. For mutually exclusive projects choose one project over others , accept the project with the highest positive NPV.

For mutually exclusive projects, accept the project with the highest IRR that is greater than required rate of return. Break-Even Analysis. Break-even analysis is a type of cost benefit analysis to identify at what point if ever benefits equal costs Hoffer, George, and Valacich. The break-even point is usually expressed as the amount of revenue that must be realized for the firm to have neither profit or loss. It expresses a minimum revenue target. Marshall, McManus, and Viele It can be expressed in numbers or by the use of graphs.

An example of Economic valuation method. After determining costs and benefits of a new system, the system analysts evaluate the project using NPV, IRR, Break-even analysis, or other methods. Also, using a time diagram is helpful to illustrate the timing of cash flows, especially for situations involving cash flows at the different points in time that are not equal Baker and Powell Other Economic Feasibility Methods.

Also, there are other financial methods that are used to evaluate the project investment. Technical Feasibility. Assessing technical feasibility is to evaluate whether the new system will perform adequately and whether an organization has ability to construct a proposed system or not.

The technical assessment help answer the question such as whether the technology needed for the system exists, how difficult it will be to build, and whether the firm has enough experience using that technology.

One examples of the technical feasibility is shown in the credit union management. However, one thing to keep in mind is that a project with the highly risk may still be conducted. Most company would have the reasonable combination among high-, medium-, and low-risk projects. Hoffer, George, and Valarich. Operational Feasibility. Assessing operational feasibility is to gain an understanding of whether the proposed system will likely to solve the business problems, or take advantage of the opportunities or not.

It is important to understand how the new systems will fit into the current day-to-day operations of the organization. Also, system analysts need to assess whether the current work practices and procedures support a new system and how the organizational changes will affect the working lives of those affected by the system.

Schedule Feasibility. Assessing schedule feasibility is to assess the duration of the project whether it is too long to be complete before it is useful. System analysts have to estimate how long the system will take to develop, and whether all potential timeframes and the completion date schedules can be met, as well a s whether meeting these date will sufficient for dealing with the needs of the organization.

The examination of a system or problem with the goal of either improving an existing system or designing and implementing a new one. As a science, systems analysis is related to cybernetics, a branch of engineering that studies the behavior of systems. System analysis is a detailed study of all important business aspects under consideration and the existing system and thus the study becomes a basis for the proposed system may be a modified or an altogether new system. Objectives of the system analysis are to know how a system currently operates, and to identify the users requirements in the proposed system.

Feasibility Study

Feasibility Study in Software Engineering is a study to evaluate feasibility of proposed project or system. Feasibility study is one of stage among important four stages of Software Project Management Process. As name suggests feasibility study is the feasibility analysis or it is a measure of the software product in terms of how much beneficial product development will be for the organization in a practical point of view. Feasibility study is carried out based on many purposes to analyze whether software product will be right in terms of development, implantation, contribution of project to the organization etc. Types of Feasibility Study : The feasibility study mainly concentrates on bellow five mentioned areas.

Understanding Types of Feasibility Study, and Its Importance

Let us now describe the different phases and the related activities of system development life cycle in detail. Preliminary system study is the first stage of system development life cycle. This is a brief investigation of the system under consideration and gives a clear picture of what actually the physical system is?

The growth and recognition of project management training have changed significantly over the past few years, and these changes are expected to continue and expand. And with the rise of project management comes the need for a feasibility study. It tells us whether a project is worth the investment—in some cases, a project may not be doable. A well-designed study should offer a historical background of the business or project, such as a description of the product or service, accounting statements, details of operations and management, marketing research and policies, financial data, legal requirements, and tax obligations. Generally, such studies precede technical development and project implementation.

A successful sport or recreation facility is the result of thorough planning. Without adequate planning, the facility will probably fail — fail to meet the current and future needs of the community, fail to meet financial goals or fail to be managed effectively. A feasibility study should critically assess a proposal to build a facility, and enable the client the owner to make an informed decision about whether to proceed with the proposed project. It should consider all the alternatives within the scope of an identified need in order to establish the most effective investment of funds. It should analyse the social and financial impacts of the proposal and identify the risks involved by studying:.

Сьюзан знала, что остальное - это штурмовая группа АНБ, которая, перерезав электрические провода, ворвется в дом с автоматами, заряженными резиновыми пулями. Члены группы будут уверены, что производят облаву на наркодельцов. Стратмор, несомненно, постарается проверить все лично и найти пароль из шестидесяти четырех знаков. Затем он его уничтожит, и Цифровая крепость навсегда исчезнет из Интернета. - Действуй своим маячком очень осторожно, - сказал Стратмор.  - Если Северная Дакота заподозрит, что мы его ищем, он начнет паниковать и исчезнет вместе с паролем, так что никакая штурмовая группа до него не доберется.

Сьюзан быстро встала и, расплескивая воду, потянулась к трубке, лежавшей на краю раковины. - Дэвид. - Это Стратмор, - прозвучал знакомый голос. Сьюзан плюхнулась обратно в ванну. - Ох! - Она не могла скрыть разочарование.  - Здравствуйте, шеф. - Думала, кое-кто помоложе? - засмеялся Стратмор.

 Какого черта ему здесь надо? - спросил Стратмор, как только они с Сьюзан оказались за дверью Третьего узла. - Как всегда, валяет дурака, - сказала Сьюзан. Стратмор не скрывал недовольства. - Он ничего не спрашивал про ТРАНСТЕКСТ. - Нет.

La Vespa. - Cinquanta mille.

 Табу Иуда, - произнес тот как ни в чем не бывало. Беккер посмотрел на него с недоумением. Панк сплюнул в проход, явно раздраженный невежеством собеседника.

Но он так долго трудился над Цифровой крепостью, что вряд ли ему захотелось бы к ней возвращаться. Сьюзан понадобилось некоторое время, чтобы все это осмыслить. Она вдруг поняла стремление коммандера к необычайной секретности в шифровалке. Стоящая перед ним задача была крайне деликатна и требовала массу времени - вписать скрытый черный ход в сложный алгоритм и добавить невидимый ключ в Интернете.
