     Phases in assimilating
     emerging technologies

1. Technology identification and investment

2. Technological learning and adaptation

3. Rationalization and management control

                                          block C
       Phase 1: Technology Identification
Initiated by decision to invest in ICT
      • one or more complementary project developments
      • lack of precision in cost estimation and ultimate stream of benefits
      • each step characterized by much uncertainty
reasons for failure
      • vendor failure
      • discovery that technology is inappropriate to the firm
      • poor user involvement
      • lack of management attention
      • bad choice
fault only discovered after 1 or 2 years
result: not clear technical disaster , but unwillingness to invest more
        perceived as adding more work to the organization
        significant cost overruns
    Phase 2: Technology Learning and Adaptation


   involves learning to adapt new technology to particular
    tasks beyond those identified in the initial proposal

   often quite different benefits than those anticipated

   projects still highly uncertain in their cost and benefits

   typical example are knowledge systems or CAD/CAM
       insufficient understanding of possibilities leads to stagnation
        and competitive disadvantages

   management in adaptive manner permits management to
    capture , develop, and refine new understanding of IT
    Phase 3: Rationalization/Management Control


   Change in organization’s approach to the technology
       continued evolution to ones originally not considered
       development of precise controls for guiding the design and
        implementation of IT systems
       various aspects of project life cycle are analyzed
       role of IT staff and users becoming clearer
       results becoming more predictable


   failure if excessive controls are developed
       controls can be so onerous that profitable expansion of the
        use of IT is inhibited and prevents logical growth (p379)
       Phase 4:Maturity/Widespread Technology
       Transfer

   Program of technical diffusion
        expand experience gained in one operating division

   A firm is confronted over time with a series of waves of
    technologies

   assimilation of several technologies in different phases



    To enable and encourage unprogrammed or inno-
    vative activity , it is recommended that organiza-
    tions make special and separate provisions for it.
            Special units for innovative purposes
         Emerging Technology Group
   Often initially in IT at level of operations and applications
   Difference between leading and lagging companies is the
    early creation of the ET group
   Sometimes put outside IT , to help ensure that it is not
    swamped by the IT control philosophy

     Characteristics of effective management of ET groups by phase
    Management        Innovative-phase          Control-phase
       issue            effectiveness             efficiency
Organization         Organic (ET)          Mechanistic (trad IT)
Management control Loose , informal        Tight
Leadership           Participating         Directive (telling,delegating)
         Innovative Phase
   atmosphere in ET group : exploratory, experimental
   organizational structure and management controls must
    be loose and informal
   cost accounting and reporting : flexible
   no requirements for cost-benefit analysis
   leadership : participating
   temporary relaxation of performance standards
   ET independent unit due to growth in information centers
   ET responsible for intra-organizational technology
    transfer
       Merging the Islands of IT

Three Islands
        • Office support
        • data processing
        • telecommunications
   Integration required for several reasons
    1. all three areas require
        •   large capital investment
        •   large protracted projects with complex implementation
        •   extensive user training
        •   more and more supplied by one single vendor
    2. key sectors of all three islands physically linked in a network
    3. dominant suppliers market products as base for co-ordinated
       automation of three islands
         Reasons for merging

   decisions in each island involve large budgets and
    complex technical and cost evaluations , whereby
    similar staff backgrounds are needed to do the analysis

   great similarities exist in type of management skills and
    staff needed to do the implementation

   most applications require integrated technological
    networks to handle computing , telecommunications
    and office support

    Conclusions on Architectural Alternatives

   Merge technologies and distribute hardware and data must be
    managed carefully in combination
   periodic re-examination is needed
     establish a permanent corporate policy group
     uniformity in management practice should not be pushed too far
     respect differences in international activities
     address the issues in a broad strategic fashion
           •   corporate organization structure
           •   current operating administrative processes
           •   corporate strategy and direction
           •   availability of human resources
     ensure adequate innovation-phase investment in experiments
           • ensure proven expertise is distributed
     ensure balance between long-term and short-term needs
