Value creation in a networked environment
Benefits from Investments
Category I: Platform improvements (NC)
Organizational benefits

Improve ability to share
information, communicate,
coordinate, and control
activities inside the
organization
Market/Industry benefits

Improve ability to share
information, communicate,
coordinate, and control
activities with customers,
suppliers, and business
partners
Category II: Options Value (Internet-based)
Organizational benefits

Increase functionality,
flexibility, and “useful life”
of the internal ICTinfrastructure
Market/Industry benefits

Increase functionality,
flexibility, and “useful life”
of the industry ICTinfrastructure
Sample metrics

Lower operating and maintenance cost

The learning environment
Assimilating Emerging
Technologies
Phases in assimilating
emerging technologies
1. Technology identification and investment
2. Technological learning and adaptation
3. Rationalization and management control
4. Maturity / widespread technology transfer

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 innovative activity , it is recommended that organizations 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

Organic (ET)
Control-phase

Mechanistic (trad IT)
Management control Loose , informal
Tight
Leadership
Directive (telling,delegating)
Participating
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
