Chapter 16 Strategies for Global IS Development (A critical review of a critical analysis) MIS 4/680, Chapter 16
Basic Ideas of This Section • Developing global systems is risky • There are solutions, but costly • Managing global development teams is risky • Designing and operating global systems are risky ventures • Certain kinds of systems (ERP mostly) are likely candidates with their own problems MIS 4/680, Chapter 16
Basic Ideas of the Chapter • Developing global IS is difficult • Strategies are needed to lower risk (which is significant) • Most of what we have to choose from is modeled on existing development strategies • The basic tensions are core vs. periphery, custom vs. package and internal vs. external. MIS 4/680, Chapter 16
Basic Ideas of the Chapter -2 • Selection of strategy depends on four sets of characteristics: • Organizational • System • Core/Periphery match • IS Department What else other than the weather could have an influence anyway? MIS 4/680, Chapter 16
Global IS Development Strategies Development with a multinational design team (MDT) Parallel development (PD) Central development (CD) Core vs. local development (CL) Best-in-Firm Software adoption (BIF) Outsourced custom development (OD) Unmodified package software acquisition (UP) Modified package software acquisition (MP)* * -- in practice all acquired packages are modified to some extent MIS 4/680, Chapter 16
Why This List? • These eight “strategies” actually overlap significantly and do not include all possible “strategies” • Classification scheme is arbitrary, but useful • Primary tensions affect strategic position of organization • Coherence of team and alignment with co. goals are primary quality and cost factors • In fact, organizations evolve through these strategies over time anyway. MIS 4/680, Chapter 16
Later, the core and periphery compromise on services implemented: CL In the early corporate stages, all development is handled centrally: CD Later, elements at the periphery develop their own needs and systems: PD Evolution of Global IT Development Next, the firm either adopts best-in-firm (BIF) or puts together a multinational design team Which is really just another way of exercising core control MIS 4/680, Chapter 16
Evolution…ct’d • Central development first; countered by • Peripheral parallel development; compromised by • Core vs. local development; then negotiated through either • Best-in-firm or multinational design team • But solution might best be brokered through an outside outsourcer or by buying modifiable packages MIS 4/680, Chapter 16

Hurricane in South Florida Hurricane will destroy our data center Cost to us if data center is destroyed Risk Assessment Risk = Σ (risk factors) Risk Factor = Probability of harmful event * Probability that event will cause harm * Cost of harm. MIS 4/680, Chapter 16
Probability of destructive hurricane in any year=0.5 Probability of our data center being destroyed by hurricane = 0.03 Cost to us if data center is destroyed = $1,000,000 Risk Assessment Risk Factor = Probability of harmful event * Probability that event will cause harm * Cost of harm. Our exposure this year to this particular risk factor is the product of 0.5, 0.03 and $1,000,000, which is $15,000. Hence we should spend up to $15,000 to counter or reduce this risk. Note: These numbers and values are not static and may change abruptly or over time. All estimates are controversial and subject to debate. MIS 4/680, Chapter 16
McFarlan’s Risk Analysis • Risk is due to three factors: Size of project, technology gap and project definition stability. • Global projects are all “large” • Global projects are all subject to strong technology strains thus increasing “gap” • Global projects are generally fluid and have multiple parties and interests and are subject to many stresses • Thus global project risk is always “High”. MIS 4/680, Chapter 16
So What to Do? Know what might happen and its causes • If Risk is High, we need to counter one or all of the three risk factors: • P(harmful events) – managed via planning • P(harm from harmful events) – managed via toughening, skilling, control • Recovery costs – managed by contingency planning, redundancy, control • McFarlan describes these along two dimensions: integration and formalization Take action to prevent harm from event or failure to react appropriately Have plans in place to repair damage, recover operations MIS 4/680, Chapter 16
Solutions (á la McFarlan) • Integration (implicit structure) • Internal: team meetings, professional leadership, mutual familiarity • External: user leadership, user communication and direction • Formalization (explicit structure) • Planning: Formal planning methods • Control: Status reviews, change management, organizational learning MIS 4/680, Chapter 16
