Flexibility to respond to systems Costs and benefits of information systems ( + ) ( - ) ( +, - ) address subunit interdependencies subunit needs for locally unique information 3. Costs of designing and implementing information • Note: tradeoffs might be different for each sub-unit. • Most successful if sub-units: (1) interdependent and (2) not highly differentiated.

Kirsch, “Strategic Data Planning: Lessons From the Field”, MIS Quarterly , March 1992, pp. 23. 10Benefits from Integrated, Sharable Data + • Improve communications across subunits (view for top mgt) – Data integration facilitates the collection, comparison, and aggregation of data from various parts of the organization, leading to better understanding and decision making when there are complex, interdependent problems. Devlin Electronics: Issues: They found a number of interlocking problems: lant capabilities, and plants Outcome: corrective action. ML On-time deliveries (a critical competitive issue in the semiconductor market) fell to only 70 percent, a multi-disciplinary team at Devlin Electronics used organization-wide integrated scheduling data to track how production schedules were made, changed, and adjusted by the many different groups involved. some plants were not properly updating their inventory levels and equipment conditions, marketing was overriding the schedule without regard to pwere overriding the system without regards to plant capabilities, and plants were overriding the system without regard to critical order requirements. Organizational-wide integrated data allowed Devlin to understand its problems and take On time delivery improved from 70 percent to 98 percent Merrill Lynch (ML) - Current State: has identified data integration issues and has launched several initiatives to standardize a minimum set of data definitions that will leverage the benefits of data integration within their different systems. Example: Venezuela 11Benefits from Integrated, Sharable Data cont.+ • Improve operational coordination across subunits (between units) – As the interdependence between subunits
