Costs & Benefits from IS
• Economic aspects of IS (or IS economy) is assessed in planning of IS as well during IS production stage.
• Cost/Benefit analysis is a necessary component in any assessment of IS economy.
3 of 14
Tangible Costs
- Direct investment in software & hardware (one time)
- IS installation & employee training (one time)
- Operating costs for an IS (recurring) – expenditures on software licences, labor costs of IS staff, IS maintenance, overhead for facilities, expenses of communications carried out by computer networks partaking in IS.
- Loss of money and time with new IS that does not perform as expected (opportunity cost).
- Total Cost of Ownership sums up all the costs in a system life cycle.

Intangible Costs
- Effort put in learning a new IS and associated process
- Employees’ loss of work motivation due to new processes/IS
- Employees’ resistance to new processes/IS
- Lower customer satisfaction due to improperly performing IS
- Limitations in decision making when a new IS cannot deliver reports managers need to make decisions.
- Note that intangible costs may result in tangible costs.

Tangible Benefits 1/2
- Savings on many counts:
- savings on labor expenses
- savings due to reduced process time (e.g., reducing inventory costs in supply chain process)
- savings due to avoiding to add more employees when improved process/IS can carry a larger volume of operations
- Organizational performance gains: new IS & process organizational productivity (output value/input cost) financial returns (profit figures).

Tangible Benefits 2/2
- Better decision making resulting in income increase (e.g., moving
into new product and geographical markets)
- Cutting losses by improved management control (e.g., ERPS case
of detecting fraudulent purchases)
- Data error reduction eliminating waste of business time & labour
for repeated tasks.
7 of 14
Intangible Benefits
- Customer value that does not translate directly into monetary gains for a company
- Better control and decision making, which do not translate readily into monetary gains
- Improvement in the appearance of reports and other business documentation (better quality but no more money).
- Increased knowledge capabilities (note: these are a condition for making more attractive products, but before this products are made and sold no monetary gains accrue).

Financial Assessments of IS Economy
• 1. Returns’ size focus: Various ratios of how much an IS returns in relation to its costs (Benefit/Cost Ratio, Net Present Value, Return on Investment):
– The higher the ratios, the more economically valuable the IS
– Present value of money used (future returns as well as costs discounted for some rate) as finances flow over years (NPV function in Excel)
• 2. Returns’ timing focus: Assessment of when returns will occur (e.g., Break-Even Analysis)
0 1 2 3 4 Time (years)
- The shorter the wait period, the more economically
valuable the IS.

Mixed Methods of AssessingIS Economy 1/2
1. Portfolio Analysis
– The focus is on controlling risks that different systems can bring
– Risks: potential known difficulties (complications, problems)
– In planning IS, different IS projects compared on risks they bear (e.g., completion within budget & time, technology demands, size of organizational change required)
– Risk = Weight (impact) of problem X Probability a problem will happen
– Risk can be thought of as a special and critical cost
– Riskier projects: Expensive systems*, new technologies, and larger org. changes (e.g., enterprise systems)

Mixed Methods of AssessingIS Economy 2/2
2. Balanced Scorecard
– The focus is on achieving organizational goals
– A combination of tangible and intangible benefits in select areas – finances, customer relations, key processes, growth potential, anything else important for a company.
– IS contribution to these performance indicators is assessed periodically.

Software and Hardware Acquisition
• Three options: Make, Buy, Rent
1. In-house Development (company's IS Department does programming, hardware acquisition, and IS installation)
2. Buy:
– Off-the-shelf software (e.g., Microsoft Office, SAP)
– Buy custom-built software (a software vendor writes software according to the client company’s requirements).
– Note: If there is a system development capability in the IS Department, the buy options are called “outsourcing” (sourcing outside of own company)
• For pros & cons (benefits & costs) see the chapter.

• 3. Rent:
– Annual licencing of software or hardware
– Rent via the Cloud (partial or total IS services).
• Cloud Advantages:
– Reduce costs: pay-per-use, avoiding development & maintenance costs
– Client benefits from new IT as vendor keeps updating it to remain competitive gains in client’s business processes.
• Cloud Disadvantages:
– Synchronizing business processes between client and vendor
– Risk of compromising confidentiality of business data
– Vendor lock-in (it is hard to get out of Cloud as a company relies more on a cloud vendor)
– Unexpected changes in pricing services.

Summary
• Costs of IS can be tangible (expressed in monetary terms) & intangible (all other forms). Examples of tangible costs are investment in computer software and hardware, and system’s operating costs.
• Benefits of Information Systems can be tangible & intangible. Examples of tangible benefits are cost reduction and income gains.
• Financial Assessments of IS economy focus on the size of returns (e.g., NPV) and on timing of returns (e.g., payback period).
• Mixed Assessments of IS economy cover tangible and intangible C/B (portfolio analysis, and balanced scorecard).
• Software can be developed by the company’s IS department, purchased, or rented; hardware is usually purchased or rented. Each option has pros and cons.
• Cloud (cloud computing) is the trendy rental option with significant pros & cons.
