In the context of ICSE’19 Software Engineering and Education Track (SEET), I presented a paper on Dual-Track Agile in Software Engineering Education. The presentation focussed on two questions: (1) Why do we need to teach Interaction Design (IxD) to Software Engineering (SE) students (http://se-edu.org/why-teaching-interaction-design/)? and (2) How could we teach IxD while staying away from “Big-Design-Up-Front” (http://se-edu.org/dual-track-agile-in-software-engineering-education/)?

Course objective
Enable students (M.S. in Software Engineering)
to design and implement software systems that
are at once useful, usable, and enjoyable to use
while making a unique contribution to society

Course topics
Interaction design and software product management
in the context of dual-track agile

Dual-track agile is at the intersection of Human Computer
Interaction (HCI) and Software Engineering (SE)

Why do we
need to teach
Interaction
Design?

6. © 2019 Cécile Péraire
If we don’t teach interaction design, our students
“might get a sub-optimal design right, but will
almost never get the right design” (Bill Buxton)
Explore various equally viable alternatives

Co-evolve Problem and Solution spaces

Interaction design supports creativity.
It encourages students to explore early solution concepts
so they can deeply understand the problem,
select the best alternative,
and hence create the right solution.

Introduce Interaction Design (IxD) and
Software Product Management (PM) practices

Stay away from teaching “Big-Design-Up-Front”
2012-V0: No Process Model
IxD-PM practices applied sequentially
(no implementation)
2018-V2: Dual-Track Agile
(based on Pivotal empirical study)
Concurrency between IxD-PM practices
and MVP implementation
2015-V1: Double-Wheel
(adapted from UX Book’ Wheel)
IxD-PM practices applied sequentially
followed by MVP implementation
MVP: Minimum Viable Product

Dual-track agile is introduced in a semester-long project
Students propose their own projects
by identifying product opportunities
with unique contribution to society
Students auto-form their teams
based on project interest
Students recruit their own stakeholders
