Timetabling for 2006
Consultative Forum
02 February 2005
1. Objectives
To outline plans for producing a comprehensive 2006
academic timetable for the Kensington campus
To set the proposed changes in the context of an
expanded set of functions in myUNSW for Staff
To obtain support from faculties and schools on those
aspects of the proposal that are beneficial to them
(or largely neutral)
To identify issues and concerns that may affect each
faculty’s ability to participate fully in the revised
timetabling business process
To constitute a timetabling reference group
To reach consensus on the best way forward.
2. The problem
What’s wrong with the timetable?
Low effective utilisation of physical resources and
time
Poor choices for students, especially in combined
programs
No coordinated strategy for updating the academic
timetable
Some parts of the timetable are locked into a 1970s
time warp
No way of investigating feasibility of new programs or
effect of changes in teaching space availability
UNSW uniquely uses no scheduling tools

3. Options
1. Do nothing. Probable consequences:


Increased demands on physical space: more buildings
required
More difficulty in introducing courses and new or modified
programs
2. Construct complete timetable for selected faculties


Blacked out bookings entrench inequities and inefficiencies
Little gain (except in experience) unless fairly extensive
3. Construct complete timetable for all feasible faculties


New timetable can be based on established need rather than
historical accident
Significant challenges to capture all relevant parameters,
especially course compatibility requirements based on
program rules
4. Proposed approach
Brief History




1990s: issue raised repeatedly at Academic Board, no resolution
Since 2003: analysis of time and room utilisation, faculty
consultation (funded by Facilities Dept)
Oct 2004: Academic Services Committee recommends approval of
project, later endorsed by Academic Board
Dec 2004: Funding provided by DVC Resources. Sponsored by
DVC (Academic)
Principles





Improve utilisation, goal is accepted standard of 75% (frequency
x occupancy) compared to current 50%
Increase available course combinations for students
Smooth chronological peaks
Level the playing field for recently introduced courses
Accommodate preferences where possible
Proposed approach – new business process
Class scheduling requirements are captured in NSS



Based on schedule from previous year
New fields created on class schedule for timetabling
parameters such as expected enrolment, room requirements,
eLearning needs etc
Some optional fields become mandatory to improve data
integrity and quality
Provisional schedule generated using external engine
(Syllabus-Plus Course Planner)
Schedule imported to NSS, bookings to CATS
Casual bookings and low-enrolment course needs
forwarded to CATS
Most interaction occurs via myUNSW for Staff
5. Scope
What’s included and what’s not?
Courses: all on-campus above minimum threshold enrolment


All regular large- and small-group teaching activities included
Small Honours seminar courses and similar offerings remain school
responsibility
Sessions: 2006 S1 and S2. X1 and X2 from 2007.
Faculties: all Kensington except undergraduate Medicine (at least
initially). ADFA, CFA, Singapore: 2007.
Staff scheduling: not yet (implemented after 2006 with faculty
agreement)

Staff availability constraints may still be incorporated
Students: allocation of students to classes is not in scope: existing
on-line enrolment procedures apply
6. Integration
Timetabling is just one aspect of maintaining rules governing
what students must or may enrol in to complete their program
Staff should be able to see and manage all aspects of







Calendars
Offerings and enrolment constraints (course catalogue)
Program rules (handbook, or a more structured system)
Class timetable requirements and room needs
Class activities: in-person, eLearning, distance, exams
Class operational schedule: response to changes in demand
Roles for teachers, administrators and supervisors – including Vista
roles
Maintain teachers (according to to school/faculty procedures)
Accessed and updated via myUNSW for Staff
Eventually supports on-line self-service advising processes

7. Some issues – technical
UNSW has little expertise in the use of scheduling software
The volume, complexity and volatility of existing program
rules may make a feasible greenfield timetable elusive
Stage 1 rules are captured in potentially usable form (Sitar),
but many rules are expressed as overall requirements
(courses listed independent of stage)
Not all classes are fully described on NSS


Activities missing; components misnamed
Course linkages not always explicitly recorded
NSS and CATS are only partly synchronised

8. Some issues – policy
CATS-2 system exacerbates scheduling problems and low
utilisation figures (yet some reserve school space is justified)
Need for wider range of learning space, yet no drop in demand
for conventional rooms
Reluctance of some faculties to record small-group classes on
NSS
Reluctance of some faculties to pre-schedule small group
classes at all
Possible reluctance to accept wider range of teaching hours
Conflicting needs and wishes
9. Some issues – operational
Demand is notoriously difficult to predict: how easy will it be to
schedule a new class quickly or cancel an non-viable one (with
automatic advice to the students affected too)?
Room requirements can change after enrolment (low/high
demand; disabled facilities required)
Staff may not be available to teach at the scheduled time
