Lessons learned play a valuable role in understanding the dynamics of
building immunization registries. These extend beyond technical issues
. Arizona has identified 10 steps in the natural evolution of a system
that are leading to a successful state immunization registry developm
ent project. Identifying the technical solutions for implementing a re
gistry is somewhat straightforward. Providing a cost-constrained, user
-efficient, timely, and implementable solution is somewhat harder. Eli
minating barriers and convincing providers to participate to create a
''win-win'' environment for all involved is harder still. Maintaining
user enthusiasm and energy is the challenge. The Arizona immunization
project has identified and is following 10 steps that are key to meeti
ng these challenges and achieving the required success. The steps are
as follows: (1) establish a coalition of statewide private and public
partners; (2) develop a technical plan; (3) review the plan with the c
ommunity of providers and associated immunization organizations; (4) s
ecure adequate funding; (5) create an integrated development team that
includes technical, immunization-specialist, and user-support members
; (6) market, educate, and sell the solution to providers, schools, nu
rse associations, managed care organizations, and parents on the syste
m; (7) develop and test components of the system in a pilot mode, buil
ding and expanding upon success and not being afraid of failure; (8) m
aintain project visibility; (9) provide ongoing and timely user suppor
t and interaction, listening to providers; and (10) change with the ti
mes, adapt the program as the need arises. Medical Subject Headings (M
