1. Building a Great City – Together
IT Best Practises - Enabling City
Services from the Ground UP
Bob Gaspirc, Manager GCC

2. Problems cannot be
solved at the same
level of awareness
that created them.

3. What makes a great City?
• a great city is one that is known around
the world for the quality of life it offers
its citizens.
• It’s safe, strong, creative and clean.
• It has a great transit system.
• And leaves no one behind by creating
opportunity for all.

4. Toronto is home to 2.7m people

5. Toronto is a place of work

6. Toronto:
A place to play

7. A place to learn and grow

8. A place of
inspiration to
many

9. Toronto is a major centre of
economic growth and
opportunity for Ontario and
Canada

10. Toronto is... Diverse and Multicultural

11. • Our population
continues to grow
• 2.6 million more
people will move
to Toronto by 2021
11

12. Who will need 1.6 million more jobs . And
12

13. … 1.25 million more homes 13

14. By 2021 we will need 19
additional lanes of
expressway capacity to move
suburban commuters to jobs
in the City and City residents
to jobs in the 905 region
which cannot be effectively
served by public transit.

15. From a simplistic point of view
Uncontrolled growth may ...
• Lead to more air pollution
• Limit our ability to attract new business
15

16. Globalization and new telecommunication
technologies mean ...
16

17. …can flow into the City … or flow out of it.
17

18. We need to grow,
we need to grow smarter

19. What do we want ?
Toronto is a caring and friendly city
Toronto is a safe, clean, green and sustainable city
Toronto is a dynamic city
Toronto invests in quality of life

24. IT Service Management

25. Agenda
 What is IT Service Management/ITIL?
 Continual Service Improvement Process
 ITSM/ITIL Status at the City of Toronto
Q & A
25

26. What is ITSM?
IT Service Management
A best practise set of specialized
organizational capabilities for
providing value to customers in
the form of services. IT Service
Management takes the form of a
set of functions and processes
for managing services over their
lifecycle.
26

27. ITIL is an approach to ITSM
• Service Strategy
Design, develop, implement service management
• Service Design
Design and develop services and service mgt. processes
• Service Transition
Transition new and changed services into operations
• Service Operation
Manage IT Service delivery and support
• Continual Service Improvement
Create and maintain business value through
better service design, transition and operations
Describes the organisation of IT resources to deliver
business value, and documents processes, functions
27 and roles in IT Service Management

32. What is CSI?
CSI focuses on maintaining value for
customers through the continual
evaluation and improvement of the
quality of services and the overall
maturity of the ITSM service lifecycle
and underlying processes.
32

33. What is CSI?
The primary purpose of CSI is to
continually align and realign IT
services to the changing business
needs by identifying and
implementing improvements to IT
services that support business
processes.
33

34. Continual Service Improvement
Plan, design, develop, deploy CSI Process:
– Generate and manage process metrics
– Formalize Process Maturity
Assessments
– Conduct Process Compliance Audits
– Implement Process defect tracking and
enhancement repository and
procedures

support the delivery of public services

71. Service Improvements
• Provide spatial data on a known and
dependable schedule
• Provide meta-data, warranty, fit for use
statements
• Obtain contractor certificates: QC/QA
• Enable distributed data maintenance
• Coordinate user training regarding use of
tools

72. We need spatially enabled
technologies to document events

Environment

73. WHAT IS TOPOGRAPHIC MAPPING ?
• A map “view” that represents the
horizontal and vertical positions of
features
• Distinguished from planimetric by the
addition of relief & contours
• 3D mapping introduces the concept of 3D
planimetric

74. How do we model topo features?
