WAYS TO EVALUATE OUR STRATEGY
"How do we know if our strategy is on the right track?"


Basis for         Why?         - Does it leverage our competencies?
the strategy                   - Does it build on our history & reputation?
                               - Does it exploit competitive dynamics?
                               - Does it reflect trends in market conditions?

Depiction of      What!        - Is it clear and powerful enough to guide us?
the strategy                   - Is it compelling to our prospective partners?
                               - Is it distinctive enough to command attention?

Consequences      So...        - Does it give us organizational focus?
of the strategy                - Can it generate valuable points of view?
                               - Does it drive specific products & services?

A NEW DIGITAL ERA HAS ARRIVED: UBIQUITY

The steady quantitative progress of the past 40 years - more MIPS, more MBs,
more transistors, etc. - has fostered a qualitative change. BIOLOGICAL MODELS
OF THE ECONOMY ARE REPLACING MECHANICAL ONES. MOMENTUM AND INNOVATION WILL BE
MORE IMPORTANT THAN CONTROL.

CONSEQUENCES OF UBIQUITOUS TECHNOLOGY
"PSC has a clear vision of what's coming."

IN THE CASE OF COMPUTERS AND NETWORKS, MORE IS DIFFERENT.
At 1 million nodes, it's a university research network, with many discussion
groups; at 100 million nodes, it's a global platform for commerce and
communication.

DIGITAL TECHNOLOGY: NOT JUST FOR PROPELLER-HEADS ANYMORE.
Chips and software are present in products ranging from ears to toasters to
toys. In the US alone, 45% of adults have net access; by 2000, 36 million US
households and 380,000 businesses will be online; women account for 60% of US
online shopping. Asia and Europe are already ramping up for similarly rapid
growth.

INVESTING MORE TO GET MORE.
Yesterday's IT investments, made primarily to cut costs and streamline
processes, are now a foundation upon which companies can build new revenues. On
this base, relatively targeted investments can reap relatively colossal
rewards.

NOBODY'S DRIVING THE BUS.
Thirty years of aggressive IT investment has produced a thicket of platforms,
standards and other interdependencies that go well beyond what managers - or
even conventional outsourcers and integrators - can control. IT services firms
must respond with creativity and continual reinvention.

HOW OUR STRATEGY CAUSES US TO ACT
"PSC's approach is novel, bold, and creative."

We build new kinds of capabilities
     powerful intranets like TRAIN, comprehensive CRM offerings, rapid
     reengineering, user-centered strategies

We blaze new paths to market
     Value webs; cross-industry, cross-competency systems like e-treasury,
     e-home, and health care network

We foster reward-sharing relationships
     e.g. Swiss Bank, Galileo, others

CRUCIAL BEHAVIORAL SHIFTS
"PSC's strategy will be real only when we begin to
behave in fundamentally new ways."


TARGET INDIVIDUAL CUSTOMERS
     Our vertical industry groups must decide specifically who to target and
     what value we would add.

MAKE COMPETENCIES EASILY ACCESSIBLE
     Our verticals must have instantaneous, effective ability to access
     and apply our technical and process competencies.

CLOSE DEALS QUICKLY
     PSC must be willing to move boldly and imaginatively in constructing
     partnerships, which means we have to take risks.

EXECUTE ON WHAT WE SELL
     PSC  must improve the quality, thoroughness, and reliability of our
     service delivery.

BUILDING CAPABILITIES AND ADDING COMPETENCIES
Recommendations from the New Competencies task force

PSC must continue to grow and add technical capabilities (skills, methods, and
processes we will routinely need) as well as technical COMPETENCIES
(differentiating skills and methods that we can aggressively market).

STABILIZING TECHNICAL OPERATIONS
Recommendations from the Operational task force


PSC must be an industry leader in effectively executing any projects or
programs it sells. To achieve this we will:


- -    Migrate current technical capabilities from a model that appears to be
     commodity to a value-added service

- -    Create systems that are more open, ubiquitous, and robust

- -    Create management tools that make our capabilities easier to understand,
     access, and apply

- -    Create voluntary conventions that will better leverage our routinely
     applied technical capabilities

- -    Address specific improvements in security, network backbone, networking,
     message and directory services

- -    Examine systems for cost reallocation

ACQUIRING NEW COMPETENCIES AND CAPABILITIES
Recommendations from the M&A task force


PSC must more systematically drive acquisition plans out of units, in a manner
that leverages our concept of the Emergent Economy.


1.   BUSINESS UNIT STRATEGY MUST DRIVE M & A
     -    Better screening process
     -    M & A team alignment to business unit
     -    M & A can support achievement to sales objectives

2.   CORPORATE RESOURCES MUST BE RATIONED
     -    Annual budget set by corporate
     -    Competition for resources
     -    General allocations to business units

3.   THERE MUST BE CLEAR ACCOUNTABILITY WHEN RESOURCES ARE OMITTED TO M & A
     PURSUITS
     -    Business units sponsor from initial contact thru close
     -    Define and assign budgets for pursuit & close

4.   WE MUST IMPROVE OUR ABILITY TO EFFECTIVELY INTEGRATE ACQUIRED COMPANIES
     -    Transition planning (sooner, more comprehensive)
     -    Cross functional teams, lead by business unit

5.   KEY CLIENTS, PARTNERSHIPS AND ALLIANCES WILL INFLUENCE AND INFORM BUSINESS
     UNIT STRATEGY
     -    Identify Key Accounts/Prospectus
     -    Cooperative strategy development

DELIVERING OUR COMPETENCIES
Recommendations from the Competency Life Cycle task force


PSC must combine our technical capabilities and project offices into new units
called Applied Technology Centers (ATC's). This will permit us to propagate our
skills more broadly while continually subjecting them to the discipline of
markets.


     -    Integrate competencies and POs into ATCs.

     -    Define strategy relative to competency, service line, and utility,
          which form ATC.

     -    Each competency should have business plans relative to their
          lifestyle stage.

     -    Use pilots to form ATCs for each stage of the lifecycle.

     -    Clearly define PSC sales channel strategy, the role of an integrator,
          function of ATC (level of centralization vs. decentralization).

                       What Is Our Vision of the World?
           A Propensity for Change which will yield opportunities....

The future shape of things to come:

Utilities will be forced to spend significant IT moneys to meet statutory
market restructuring "compliance" requirements, e.g. "Rule of Thumb". $100 for
@ customer. These expenditures are over and beyond normal annual IT spends.
