1 Factors to consider System component costs Methods
Selection Methods Factors to consider System component costs Methods

2 FACTORS Cost: often hard to estimate Intangibles
If technology enabled without modifications, easier to estimate development costs Still hard to know benefit impact Intangibles Market share, better customer service Better corporate image Better access to data

3 Hidden Outcomes Organizational power shifts Imposition of work methods
Get more done with fewer people Big impact on how people work Subject to technology changes

4 Hinton & Kaye (1996) Two capital budgeting approaches:
Capital investment Apply rigorous cost/benefit analysis Revenue enhancement Disregard cost/benefit details IT tends to be treated as a capital investment Maybe it shouldn’t be If critical to firm strategy If needed to keep up with competitors

5 IT Budgeting Techniques
FINANCIAL Discounted cash flow Long term – reflects time value of money Cost-benefit analysis Do not need to include time value of money Payback Quick and dirty Usually sufficient

6 IT Risk Factors Project manager ability (often hire consultant)
Experience (probably won’t have in ERP) Experience with programming Availability of critical equipment, software Probably not a problem in ERP Project team completeness Make it complete Personnel turnover Especially after adoption of ERP Project team size (make sure enough) Relative control of project manager over project team

7 Criteria Type % companies % projects Rank by value Business objectives Managerial 88% 57% 1 Support decisions 29% 7 Required (legal) 71% 13 Implicit objectives 69% 44% 3 Budget constraint Financial 68% 64% 8 Payback 61% 51% 5 Competition 28% 6 IRR 54% 2 NPV 48% 58% 4 Rate of return 16% 47% 10 Profitability index 8% 14

12 Cost Benefit Example Adopt a small ERP ($3 million) 1st year BPR
Internal team doubles in cost in year 2 Consulting costs double in year 2 Year 2 – more hardware Year 3 – finish implementation Operate ERP begins year 4 Cost of capital 20% per year

17 Value Analysis DSS benefits usually very nebulous
Keen (1981) DSS benefits usually very nebulous Unfair to apply cost-benefit analysis benefit estimates unreliable Costs - identify as in cost-benefit Benefits - leave in subjective terms Managerial decision: are you willing to pay this much for that set of benefits? Value analysis was proposed by Keen (MIS Quarterly, 5:1, 1981, pp. 1-16). It assumes that benefits cannot be quantified in monetary terms, but that costs can. Therefore, the problem is converted to a consumer-purchase decision: Is the manager willing to pay this price for this set of subjective benefits? (Are you willing to pay $40,000 for a Lexus?)

18 SMART Simple Multi-attribute Rating Technique
develop hierarchy, score alternatives, weight value =  weight x score

19 terminology objectives - what you want to accomplish
attributes - features of a thing criteria - measures of things of value tradeoffs - one alternative better on one attribute, the other better on another attribute Vendor fast, has better perceived quality, higher price ASP fast, but less control In-House slow, risky, but best fit

20 SMART technique 1. identify person whose utilities are to be maximized
2. identify the issue or issues 3. identify the alternatives to be evaluated 4. identify the relevant dimensions of value for evaluating alternatives (attribute scales) 5. rank the dimensions in order of importance 6. rate dimensions in importance, preserving ratios 7. sum the importance weights, & divide by total(wi) 8. measure how well each alternative does on each dimension(sij) 9. U =  wi sij

21 points in Step 4, limit criteria
there are only so many things a human can keep track of at one time 8 plenty if weight extremely low, drop

22 methodology Step 4: Vendor, ASP, In-house Step 5: rank order criteria
cost > quality > control Step 6: rate dimensions least important = 10 control = 10 quality = 35 cost = 50

23 methodology Step 7: sum, divide by total
cost = 50/95 = .526 quality = 35/95 = .368 control = 10/95 = .105 SWING WEIGHTING (check) give most important 100, others proportional cost = 100, quality = 60, control = 25 cost = 100/185 = .541, quality = .324, control = .135 maybe average: cost .53; quality .35; control .12

24 methodology purpose of swing weighting
the input is admittedly an approximation giving values based on a different perspective additional check should yield greater accuracy

25 scores Step 8: score each alternative on each criterion
need as objective a scale as you can get doesn’t have to be linear COST: maximum feasible = 0 minimum available = 1.0 Vendor about 0.8 Outsource 1.0 In-House 0

26 scores QUALITY: Vendor excellent 1.0 ASP less 0.4 In-House good 0.8
CONTROL Vendor average 0.3 ASP low 0.1 In-House maximum 1.0

27 recommends the Vendor system
calculation of value U =  wi sij COST QUAL Control weights scores: TOTALS Vendor ASP In-House recommends the Vendor system

28 SMART provides a very workable means to implement the principles of MAUT in fact, it can be MORE accurate than MAUT (more realistic scores, tradeoffs) identify criteria develop scores over criteria identify alternatives available, measure scores simple calculation
