Whitfield Technology Plan Mission Statement
–
We believe that Whitfield School is a world-class
institution which trains students to be leaders in a rapidly
changing, global community. Thus it is our mission to
provide members of our community with the appropriate
tools and experiences to create leaders in such an
environment.

●
Commodification of information
Need for synthesis and knowledge creation
Need to access larger team and audience
Leadership

Need for true technological literacy

Project Justification
●
Reduce Digital Divide
–
–
–
Goal #4: Seek opportunities to use
technology to access diverse resources and
communities as a means to participate in a
wider community of learners
Create replicable model for other schools
Be a mentor or host (ASP) for other schools
in transition
Project Design
Rationale
●
Reliability
–
●
Stable Linux
–
●
Tough ThinkPad (“ruggedized” for students)
Reduce malware risks and downtime
Secure Citrix
–
Tighter, accessible anywhere and FAST!
Higher reliability = Lower TCO
Rationale
●
Manage the TCO
–
–
–
–
–
Tough ThinkPads = fewer spares
Linux OS reduces cost of machine
(purchased w/o Windows OS)
Linux/Citrix combo requires less beefy
machine extending life to 4 years (from 3)
Citrix reduces software costs (concurrent use
model)
Lower unit cost = lower insurance
Rationale
●
Widen Community of Learners
–
–
–
Tool provides greater access to people and
resources
1:1 computer allows students to develop
literacy while following personal interests
Reducing TCO will hopefully lead to
increased diversity in 1:1 schools

Reliability
–

–
Per 100 laptops, we re-imaged 13
laptops/year versus 40/year at peer schools
(hardware and software failure)
Per 100 laptops, we had 5 insurance
claims/year versus 28/year at peer schools
with different hardware
Citrix has remained available 99.996% of the
time
Results
●
Manage TCO
–
–
Acquisition cost down
Day to day maintenance down
●
●
–
Fewer re-image sessions
Almost no trouble shooting due to spyware
Software cost down
●
●
We employ more open source
Concurrent licenses for Windows apps
through Citrix (except Microsoft)
