Implementation Issues

Introduction

most organizations acquiring GIS technology are relatively sophisticated

some level of investment already exists in electronic data processing

some experience w/ database management & mapping systems . . .

some combination of mainframes, workstations, Pcs

GIS technology moving into an environment w/ its own institutional structures

departments, areas of responsibility

as an integrating technology more organizational changes required

cooperation, breaking down of barriers, etc. may have been arguments FOR GIS in the first place

existing structures may be changing - e.g., centralized computing services disappearing

organizational change is often DIFFICULT to achieve and can lead to FAILURE of a GIS project

organizational & institutional issues more often reasons for failure rather than technical issues

Stage Theories of Computer Growth

several models proposed for the growth of computing within organizations

growth divided into a number of stages

most prominent model proposed by R. L. Nolan in 1973

Stage 1: Initiation

computer acquisition

use for low profile tasks within a major user department

early problems appear!

Stage 2: Contagion

efforts to increase use of computing

desire to use inactive resources completely

top management are supportive

fast rise in costs!

Stage 3: Control

efforts to control computing expenditures

policy & mgmt board created

efforts to centralize computing & control

formal systems development policies introduced

rate of increase in cost slows

Stage 4: Integration

refinement of controls

greater maturity in mgmt. of computing

computing seen as an organization-wide resource

application development continues in a controlled way

costs rise slowly & smoothly

How Does This Model
Fit the GIS Experience?

2 versions:

incremental

radical

Incremental Model

GIS is a limited expansion of existing data processing facilities

no major changes required

GIS will be managed by data processing dept. as a service

probably run on that dept.s server or mainframe

this model fits AM/FM & Land Information System applications best

notion of adding geographical access to existing administrative database

Incremental Model (cont.)

GIS acquisition is expansion of existing facilities

thus implementation really begins at Stage 2 of Nolans model (contagion)

if acquisition successful, use and costs will grow rapidly, leading to control in Stage 3

Radical Model

GIS is independent of existing data processing facilities

e.g., GIS installed on PCs instead of server or mainframe, & promoted by staff w/little or no history of data processing use

data processing dept. may resist acquisition, or attempt to persuade mgmt. to adopt an incremental strategy instead

Radical Model (cont.)

may be strong pressure to make GIS hardware compatible w/ main data processing facility to minimize training/maintenance costs

this model more likely in GIS applications w/ strong analytical component (resource mgmt., planning, etc.)

model assumes GIS will NOT require large supporting infrastructure

unlike central data processing facility w/staff of operators, programmers, consultants, etc.

Radical Model (cont.)

unlike incremental model, implementation begins at Step 1 of Nolans model

few systems progress beyond Stage 2 - process of contagion still underway, GIS is still new

stage 2 is slow with GIS b/c of need to educate/train users in new approach

Radical Model (cont.)

GIS does NOT replace existing manual procedures in many applications (unlike many data processing applications)

support by mgmt. may evaporate before honeymoon is over! No Stage 3 or 4

currently little documentation of well-controlled (stage 3), well-integrated (stage 4) systems, but. . .

this will change rapidly over next few years

Resistance to Change

many organizations are conservative

resistance to change has always been a problem in technological innovation

change requires leadership

stage 1 requires a missionary within an existing department

stage 2 requires commitment of top mgmt., similar commitment of individuals w/in departments

Resistance to Change (cont.)

despite economic, operational, even political advantages of GIS, the technology is new and outside the experience of many senior managers

Resistance to Change (cont.)

leaders take great personal risk

ample evidence of past failure of GIS projects

initial missionary is an obvious scapegoat for failure

Chrisman (1988) documents the role of various leaders in the early technical development of GIS

similar roles within organizations will likely never be documented!

Implementation Problems:
Over-Emphasis on Technology

planning teams made up of technical staff will emphasize technical issues in planning

perhaps they will ignore managerial issues

planning teams often forced to deal with short-term issues

perhaps no time to address longer-term management issues

Implementation Problems:
Rigid Work Patterns

it may be difficult for the planning team to foresee necessary changes in work patterns

a formerly stable workforce may be disrupted

e.g., some jobs may disappear!

or some jobs may be redefined, e.g., drafting staff reassigned to digitizing

Implementation Problems:
Rigid Work Patterns (cont.)

some staff may find their new jobs too demanding

e.g., former keyboard operators may now need to do database query operations

drafting staff may need computing skills

people comfortable in their roles will not seek change

e.g., people must be persuaded of benefits of change through education/training

Implementation Problems:
Organizational Inflexibility

planning team must foresee necessary changes in organization hierarchy, organizations wiring diagram

departments that are expected to interact and exchange data must be willing to do so!

Implementation Problems:
Decision-Making Procedures

many GIS projects are initiated by an advisory group drawn from different depts.

adequate for early phases of acquisition but must be replaced by a group with a more well-defined decision-making responsibility

usually painful to give a single dept. authority (funds must be reassigned to that dept.)

but this usually assures a higher rate of success

Implementation Problems:
Decision-Making Procedures

e.g., many states have assigned responsibility for GIS operation to a dept. of natural resources

consulting is then mandated from related user departments through committees

project may be derailed if any important or influential individuals are left out of the planning process!

Implementation Problems:
Assignment of Responsibilities

subtle mixture of technical, political, and organizational issues

typically made on technical grounds

then modified to meet pressing political, organizational issues

Implementation Problems:
System Support Staffing

at a MINIMUM, a multi-user GIS requires:

a system manager responsible for day-to-day operation, staffing, financing, meeting of user requests

a database manager responsible for database design, planning data input, data security, database integrity

planning team may NOT recognize necessity of these positions

Implementation Problems:
System Support Staffing

in ADDITION, the system will require:

staff for data input, report production

applications programming staff for initial development, although these may be supplied by the GIS vendor

management may be tempted to fill these positions from existing staff without adequate attention to qualifications

personnel dept. will be unfamiliar w/nature of positions, qualifications, SALARIES

Strategies to Facilitate SUCCESS

INVOLVE the MANAGEMENT

management must take a more active role than just providing money & resources

support implementation of multi-disciplinary GIS teams

help to develop organizational strategies for crossing internal political boundaries

support interagency agreements to assist in data sharing & data acquisition

Strategies to Facilitate SUCCESS

TRAINING & EDUCATION

staff and management must be kept current in the technology and applications

short courses

conferences

trade & academic journals

Strategies to Facilitate SUCCESS

CONTINUED PROMOTION

project staff must continue to promote the benefits of GIS, even after it has been adopted

ensures continued financial & political support

projects should be of high quality and value

high profile projects often gain public support

Strategies to Facilitate SUCCESS

RESPONSIVENESS

project must be seen to be responsive to users needs

continue to explore ways to make GIS quick and efficient to use

user interfaces

task automation

Strategies to Facilitate SUCCESS

IMPLEMENTATION & FOLLOW-UP PLANS

carefully developed implementation plans

plans for checking on progress

both necessary to ensure controlled management and continued support

follow-up plans must assess progress

need check points for assessing this. . .

audits of productivity

perhaps study of costs and benefits
