Objectives Understand Feasibility Study
Understand different types of benefits obtained by using the Information System Different types of cost incurred on the developing and maintaining Information System How to assess Economic Feasibility
3
Initiation and Planning Systems Development Projects
The first phase of SDLC , is the Planning, during which two activities are performed. The first activity of the Planning phase, Project identification and Selection focuses on the activities during which the need for a new or enhanced system is recognized. This activity identifies the portfolio (group) of projects to be undertaken by the organization. The project identification and selection is a pre-project step in the life cycle.
4
Initiation and Planning Systems Development Projects
The second step in the planning phase is Project Initiation and Planning which is used to conduct a more detailed assessment of one particular project selected during the first step i.e. to understand the scope of a proposed project and its feasibility of completion based on the available resources. In this phase, projects are either accepted for development, rejected or redirected. Systems Analyst plays a major role in the system development process.
5
How much effort should be expended on the project Initiation and Planning ?
The time and effort (about 10%) spent on initiation and planning activities is easily paid later in the project Proper and insightful project planning, including determining project scope as well as identifying project activities can easily reduce time in later project phases. e.g. a careful feasibility analysis that leads to deciding that a project is not worth pursuing can save a considerable expenditure of resources.
6
Why is project Initiation and Planning (PIP) such a challenging activity ?
PIP is viewed as challenging activity because the objective of the PIP is to transform a vague system request document into a tangible project description. This is an open ended process. The Analyst must clearly understand the motivation for and objectives of the proposed system, which can be made possible by effective communication among the systems analyst, users and management, as a result give rise to a meaningful project plan.
7
Project Initiating • Project Initiation, the first activity within PIP, focuses on activities designed to assist in organizing a team to conduct project planning.
8
Project Initiating The type of activities performed when initiating a project are a follows: Establishing the project initiation team. Establishing a relationship with the customer. Establishing the project initiation plan. Establishing management procedures. Establishing the project management environment and project workbook.
9
Project Planning Project Planning, the second activity within Project Initiation & Planning is the process of defining clear, discrete activities and the work needed to complete each activity within a single project. The objective of the project planning process is the development of a Baseline Project Plan (BPP) and the Statement of Work (SOW)
10
Project Planning Describing Project scope, alternatives and feasibility. Dividing the Project into manageable tasks. Estimating Resources and creating a resource plan. Developing a preliminary schedule. Developing a communication plan Determining project standards and procedures. Identifying and assessing risks Creating a preliminary budget Developing a statement of work. Setting a baseline Project plan.
11
Accessing Project Feasibility
The feasibility study decides the possibility of developing the proposed system within the budgetary, time and technology constraints. The feasibility study decides if the proposed system is cost effective from a business point of view i.e. if it can be developed given existing budgetary constraints, and if it can be developed within a given time limit and with the available technology depending on the complexity of the project.
12
Assessing Project Feasibility
Accessing feasibility is a required activity for all the information Systems projects. It determines whether a development project has a reasonable chance of success. Feasibility Study requires to evaluate a wide range of factors. Six Categories Economic Technical Operational Schedule Legal and Contractual Political 6.12
13
Assessing Economic Feasibility
The purpose for assessing economic feasibility is to identify the financial benefits and costs associated with the development projects. Economic feasibility consists of two test: Is the anticipated value of the benefits greater than projected costs of development? Does the organization have adequate cash flow to fund the project during the development period? Assessing economic feasibility is also called the Cost – Benefit Analysis
14
Assessing Economic Feasibility
Developing a cost/benefit analysis is a three-step process. Step 1: To estimate the anticipated development and operational (after system is out into use) cost. Step 2: To estimate the anticipated financial benefits (Expected annual savings derived from installation of the new system). Step3 : The cost/benefit analysis step is calculated from the detailed estimates of costs and benefits.
15
Determine Project Costs
Information Systems can have Tangible Costs Intangible Costs Tangible Costs : A cost associated with an Information system that can be measured in dollars and with certainty. From an IS development perspective, tangible cost include items such as Development cost Operational cost
16
Guidelines for Better cost Estimating
Assign the initial estimating task to the final developers Delay finalizing the initial estimate until the end of a thorough study. Anticipate and control user changes. Monitor the progress of the proposed project. Evaluate proposed project progress by using independent auditors. Use the estimate to evaluate project personnel. Study the cost estimate carefully before approving it. Rely on documented facts, standards and simple arithmetic formulas rather than guessing, intuition, personal memory and complex formulas. Don’t rely on cost estimating software for an accurate estimate.
17
Development (One-Time) Costs
One time cost refer to those associated with project initiation and development and the startup of the system. These costs includes activities such as System Development New hardware and software purchases Salaries and wages of development team Consulting fees User training Site preparation Data or system conversion 6.17
18
ONE TIME COSTS WORKSHEET
Year 0 Development costs $20,000 New hardware $15,000 New (purchased) software, if any Packaged application $5,000 Other User training $2,500 Site preparation Other Total one-time costs $42,500
19
Recurring Costs Refers to those costs associated with ongoing evolution and use of the system. These costs includes activities such as: Application software maintenance Incremental data storage expense New software and hardware releases Consumable supplies and other expenses (e.g. paper, forms, data centre personnel) Incremental communications. Telephone expenses Connectivity expenses 6.19
20
RECURRING COSTS WORKSHEET
Year 1 through 5 Incremental data storage Required:20 MB x $ $1,000 3. Incremental communication $2,000 4. New software or hardware leases 5. Supplies $500 Other TOTAL RECURRING COSTS $28,500
21
Fixed and Variable Costs
Both one-time and recurring cost can consists of items that are Fixed or variable Fixed costs refer to costs that are billed or incurred at a regular interval and usually at a fixed rate (e.g. a facility lease payment). Variable costs refer to items that vary in relation to usage (e.g. long distance phone charge)
22
Determine Project Costs (Contd.)
Intangible Costs A cost associated with an information system that cannot be measured in terms of dollars or with certainty. Intangible costs can include Loss of customer goodwill Loss of employee morale Operational inefficiency Even though Intangible costs do not enter into the calculations, they should be considered while deciding whether to work on the project or not. 6.22
23
Types of Costs Examples Procurement Consulting Costs Equipment purchase or lease Equipment installation costs Site preparation and modifications Management and staff time Project-related Application software Software modifications to fit local systems Personnel, overhead from in house development Training users in application use Collecting and analyzing data Preparing documentation Managing development Start Up Operating System software Communication equipment installation Start-up personnel Personnel searches and hiring activities Disruption to the rest of the organization Management to direct start up activity Operating Systems Maintenance costs (hardware, software and facilities) Rental of space and equipment Asset depreciation management, Operation and planning personnel
24
Assessing Economic Feasibility
Determining Project Benefits: An information system can provide benefits to an organization which usually come from two major sources: Decreased costs Increased revenues Cost savings or decrease in expenses come from increased efficiency in company operations. e.g. a new or renovated IS can automate monotonous jobs, reduce errors, provide innovative services to customers and suppliers and improve organizational efficiency, speed , flexibility and morale. 6.24
25
Assessing Economic Feasibility
Benefits can be viewed as Tangible Intangible Tangible Benefits Tangible Benefits refers to associated benefits that can be quantified i.e. can be measured easily in dollars and with certainty
26
Tangible Benefits Reducing staff by automating manual functions or increase efficiency Maintaining constant staff with increasing volumes of work Reducing paperwork cost by implementing electronic data interchange and other automation. Decreasing operating expenses such as shipping charges Reducing error rates through automated editing or validation Achieving quicker processing and turnaround of documents or transactions Reducing bad accounts or bad credits losses
27
TANGIBLE BENEFITS WORKSHEET
Benefits/Cost Saving Amount Comments Increased efficiency in mail order department $125,000.00 5 Increased efficiency in phone order department $25,000.00 1 Increased efficiency in warehousing/shipping $87,000.00 Increased earnings due to web presence $152,000.00 Increasing at 50%/year Other savings (inventory, supplies) $889,000.00 Total Annual Benefits
28
TANGIBLE BENEFITS WORKSHEET
Year 1 through 5 Cost reduction or avoidance $ 4,500 Error reduction $ 2,500 Increased flexibility $ 7,500 Increased speed of activity $10,500 Improved in management planning or Control $25,000 Total tangible benefits $50,000
29
Assessing Economic Feasibility
Intangible Benefits refer to those items that cannot be quantified i.e.cannot be easily measured in dollars or with certainty. The Intangible benefits are to be described in the BPP. Intangible benefits may have direct organizational benefits such as Improvement in employee morale Increased levels of services Increased customer satisfaction More timely information Faster decision making Reduction of waste creation or resource consumption Positive impact on society Improved work process that can improve employee morale 6.29
30
Assessing Economic Feasibility
Intangible Benefits Information processing efficiency Improved asset utilization Improved resource control Increased accuracy in clerical operations.
31
Intangible Benefits Intangible benefits do not enter into the calculations, they should be considered and be also the deciding the factor on whether the project proceeds or not.
32
Cost Benefit Analysis
33
Time value of money (TVM)
The process of comparing present cash outlays (cash spent) to future expected returns is known as Time Value of Money (TVM) The phrase time value of money refers to the fact that a dollar in hand today is worth more than a dollar promised at some time in the future. One reason for this is that we could earn interest while we waited; so a dollar today would grow to more than a dollar later.
34
Time value of money (TVM)
The development of an information system has both one-time and recurring costs Benefits from system development will likely occur sometime in the future but not from year 1. Since many projects may be competing for the same investment dollars, all costs and benefits must be viewed in relation to their present value in that year when comparing investment options.
35
Time value of money (TVM)
The rate at which money can be borrowed or invested is called the cost of capital and is called the discount rate for TVM calculations. The discount factor is like an interest rate, except it is used to bring future values back to current values. The t years from now when r is the discount rate the present value of money (Y) PVn = Y x 1 (1 + r) t
36
The Time Value of Money The present value of $1500 after one year, two years, three years is calculated as: PV1= 1500 x [1 /(1 + 0.I)1] PV1 = 1500 x .9091 PV1= PV2 = 1500 x [1/(1+0.1)2] PV2 = 1500 x = 1239 PV3 = 1500 x [1 /( )3]= 1500 x =
37
The Time Value of Money If a person has to make three payments of $1500 each at the end of a year, the total amount after three year is $ $ $1500 = $4500 To calculate the net present value of the three $1500 , payments simply add the present values calculated above NPV= PV1+PV2+PV3 NPV = NPV = In other words, the person could make a lump sum payment of $ in the beginning or $1500 at the beginning of each year.
38
The Time Value of Money Economic Analysis:
Create a worksheet reflecting the present values of all benefits and costs. The life of many information systems does not exceed five years. Therefore the cost benefits analysis calculations are to be made using five year time horizon. The management has set their cost of capital to be 12 % i.e. discount rate is 12 %
39
Commonly Used Cost Benefits Analysis
Net Present Value Return On Investment Pay Back Period ( Break Even Analysis)
40
The Time Value of Money Overall NPV is calculated as:
Overall NPV= NPV of all BENEFITS -NPV of all COSTs Over all Return on Investment (ROI) is calculated as : Overall ROI = Overall NPV/NPV of all COSTS ROI is calculated as percentage The more the ROI, the better.
41
Break Even Analysis The objective of break-even analysis is to discover at what point benefits equal costs i.e. when break down occurs. The NPV of the yearly cash flows are determined by subtracting both the one time costs and the present values of the yearly recurring costs from the present value of the yearly benefits. The overall NPV of the cash flow reflects the total cash flows for all the preceding years. The break down occurs between year 2 and 3. Since year 3 is the first year in which overall NPV cash flow is non negative.
42
Break Even Analysis Break Even Ratio =
(Yearly NPV Cash Flow-Overall NPV Cash flow)/ Yearly NPV Cash flow (15, )/15304 = .404

Assessing Technical Feasibility
The purpose of assessing technical feasibility is to gain an understanding of the organization’s ability to construct the proposed system. The analysis includes assessment of the development group’s understanding of the possible target hardware, software and operating environments to be used as well as system size, complexity and the group’s experience with similar systems.
46
Assessing Technical Feasibility
All projects have risks, understanding the sources and types of technical risks proves to be valuable tool when a project is assessed. All risks need to be managed in order to be minimized, therefore potential risks should be identified as early as possible in a project.
47
Assessing Technical Feasibility
If the risks are not assessed or managed, it can result to the following outcomes : Failure to attain benefits from the project Inaccurate project cost estimates Inaccurate project duration estimates Failure to achieve adequate system performance levels Failure to adequately integrate the new system with existing hardware, software or organizational procedures.
48
Assessing Technical Feasibility
How to manage risk on a project ? By changing the project plan to avoid risky factors Assign project team members to carefully manage the risky aspect. Set up monitoring methods to determine whether or not potential risk is in fact materializing
49
Assessing Technical Feasibility
The amount of technical risk associated with a given project is dependent on four primary factors. Project size Project structure The development group’s experience with the application and technology area. The user’s experience with development projects and application area.
51
Rules for technical risk assessment
Larger projects are riskier than small projects. A system in which the requirements are easily obtained and highly structured will be less risky than one in which requirements are messy, ill structured, ill defined or subject to the judgment of an individual. The development of a system employing commonly used or standard technology will be less risky than one employing novel or non standard technology.
52
Rules for technical risk assessment
A project is less risky when the user group is familiar with the systems development process and application area than if unfamiliar. Successful IS projects require active involvement and cooperation between the user and development groups. Users familiar with the application area and the systems development process can influence the success of the project.
53
Assessing Technical Feasibility
The selection committee should select a reasonable percentage of high, medium and low risk projects. A matrix for assessing the relative risk related to the general rules described above is shown below
54
Low structured High structured Large Project (1) Low risk (2)
High familiarity with technology or Application Area Large Project (1) Low risk (2) Very Low risk Small Project (3) Very low risk (4) Low familiarity with technology or Application Area (5) Very High risk (6) Medium risk (7) High risk Medium-low risk
55
Operational Feasibility
It is the process of assessing the degree to which the proposed system solves the business problems or takes advantage of business opportunities. The business opportunities are outlined in the systems service request or project identification study. It is related to examining the likelihood that the project will attain its desired objectives.
56
Operational Feasibility
For a project motivated from ISP, operational feasibility includes justifying the project on the basis of being consistent with the IS plan. Operational feasibility also includes an analysis of how the proposed system will affect organizational structures and procedures.
57
Schedule feasibility It relates to project duration.
The purpose of assessing schedule feasibility is to gain an understanding of the likelihood that all potential time frames and completion dates schedules for all the activities within a project can be met and that meeting these dates will be sufficient for dealing with the needs of the organization. e.g. a system may have to be operational by a government-imposed deadline, by a particular point in the business cycle(such as beginning of the season when new products are introduced) or at least by the time a competitor is expected to introduce a similar system.
58
Schedule feasibility Assessing schedule feasibility during project initiation and planning is more of a rough –cut analysis of whether the system can be completed within the constraints of the business opportunities or the desires of the users. If the system is technically feasible then the final schedule of activities produced during project initiation and planning will be very precise and detailed for the analysis.
59
Legal and Contractual feasibility
The process of understanding of any potential legal and contractual ramifications (consequences) due to the construction of the system is known as legal and contractual feasibility. Possible considerations include Copyrights or non disclosure infringements. Labour laws Antitrust legislation, limiting the creation of systems to share data with other organizations. Foreign trade regulations, limiting the access to employee data by foreign corporations Financial reporting standards. Current contractual obligations
60
Legal and Contractual feasibility
Contractual obligations may involve Ownership of software used in joint ventures License agreements for use of hardware or software Nondisclosure agreements with partners Elements of a labor agreement
61
Political feasibility
It is the process of evaluating how key stakeholders within the organization view the proposed system. Since an information system may affect the distribution of information within the organization, and thus the distribution of power, the construction of an IS can have political ramifications. Those stakeholders not supporting the project may take steps to block, disrupt or change the intended focus of the project.
62
Building the Baseline Project Plan
All the information collected during project initiation and planning is collected and organized into a document called the Baseline Project Plan. 6.62
