2.  The session will facilitate the students to know about the
different software development lifecycle models (ref:
Programming and Prototyping course) and to identify the
differences in the activities and tasks in the different
phases.
 The students will be able to explain the integration of
human-centered design (HCD) process with agile
development framework, and in particular, assume
different SCRUM roles.
o HCD process: Activities involved in the interaction design and
digital production process
o Integration of human-centered design (HCD) activities with Agile
Development Framework and Scrum Methodology/Process

3. Most of the reputed books on interaction Design (e.g. Rogers,
Sharp, & Preece, 2013, Chapter 9-15) refers to ISO (the
International Organization for Standardizations) model ISO 13407
and elaborates the following four activities.
1. Establishing Requirements for the user experience design
2. Designing alternatives that meet those requirements. Two
sub-activities: conceptual design and physical design.
3. Prototyping the alternative designs so that they can be
communicated and assessed. Can be (either or mix of) Low-
fidelity and high-fidelity prototypes.
4. Evaluating what is being built throughout the process and the
user experience it offers.
ISO 9241-210:2010 cancels and replaces ISO 13407:1999.

4.  This first edition of ISO 9241-210 cancels and
replaces ISO 13407:1999, of which it constitutes a
technical revision. The changes include the following:
— clarifying the role of iteration in the whole design process (not just
evaluation);
— emphasizing that human-centred methods can be used throughout
the system life cycle;
— explaining design activities;
— clarifying the principles of human-centred design.

5. 1. The design is based upon an explicit understanding of
users, tasks and environments
2. Users are involved throughout the design and
development
3. The design is driven and refined by user-centred
evaluation
4. The process is iterative
5. The design addresses the whole user experience
6. The design team includes multidisciplinary skills and
perspectives

6.  This part of ISO 9241 provides requirements and
recommendations for human-centred design principles and
activities throughout the life cycle of computer-based
interactive systems. It is intended to be used by those
managing design processes, and is concerned with ways in
which both hardware and software components of interactive
systems can enhance human–system interaction.
 This part of ISO 9241 provides an overview of human-centred
design activities. It does not provide detailed coverage of the
methods and techniques required for human-centred design,
nor does it address health or safety aspects in detail. Although
it addresses the planning and management of human-centred
design, it does not address all aspects of project
management.

8.  The new ISO standard for human centered design (HCD)
and the rapid adoption of the software development
methodologies under the “Agile Development Framework”
is now ISO (9241:210) standard practice since 2015.
 Agile framework led to the development of different
methodologies or software development lifecycles. Namely,
Adaptive Software Development (ASD), Agile Unified
Process (AUP), Crystal Methods (Crystal Clear), Dynamic
Systems Development Method (DSDM), Extreme
Programming (XP), Feature Driven Development (FDD),
Kanban, Lean software development, Scrum, Scrum-ban,
etc.

10.  The PACT Analysis is expected to provide sufficient
insight about need and context of use.
 Practically, PACT analysis enables brainstorming and
understanding context of use.
o People: Goals, roles, characteristics
o Activity: (task analysis)
• Role of technology – what and how;
• Role of people – what and how;
o Context: Environmental characteristics
• What are the factors
• How do/might those effect people, technology, and activity
o Technology: System goals and roles
• Functional and non-functional characteritics

11.  Deliverables of this phase
o Persona and Scenarios
o User wish list
o User journeys/stories
o UX requirements

12.  Prototypes are used extensively in the two design phases:
o Conceptual Design: Moving from requirements to first
design (e.g., what the product should do, behave and look
like)
o Physical Design (consider detail of the product including
the colors, sounds, images to use, menu design, icon
design, etc.)
 Types of Prototypes: Low-Fidelity and High-Fidelity
 Some of the prototyping techniques are: Card Sorting,
Wireframe, Storyboard, Paper prototyping, Digital interactive
prototyping, Blank model prototyping, Video Prototyping,
Wizard-of-oz prototyping, Coded Prototyping, Prototyping with
office suite applications, Prototyping with Visio, and
Prototyping with Acrobat.

13.  Evaluation occurs throughout the interaction design process.
At different stages, different methods will be more or less
effective.
o Obtaining feedback to inform early design concepts
o Deciding between different design options
o Checking/testing for usability problems
o Assessing the usability of a finished product
o As a means of involving people in the (participatory) design
process
 Approaches
o Expert evaluation: conducted by interaction designer or usability
expert or alike.
o Participant-based evaluation: conducted in collaboration - by
designer and actual users
o Others

15.  Scrum is an Agile framework for completing complex projects.
Scrum originally was formalized for software development
projects, but it works well for any complex, innovative scope of
work.
 Scrum is the leading agile development methodology, used by
Fortune 500 companies around the world. The Scrum Alliance
exists to transform the way we tackle complex projects, bringing
the Scrum framework and agile principles beyond software
development to the broader world of work.
 When Jeff Sutherland created the scrum process in 1993, he
borrowed the term "scrum" from an analogy put forth in a 1986
study by Takeuchi and Nonaka, published in the Harvard Business
Review. In that study, Takeuchi and Nonaka compare high-
performing, cross-functional teams to the scrum formation used by
Rugby teams.Mon, 13 Feb 2017 Aalborg University 15

16.  Three Roles
1. Product Owner
• Responsible for Return on Investment (ROI)
• Final arbiter of requirements questions
• Make business decisions focused more on what that on the how
2. Scrum Development Team (no hierarchy, ideally 4-9 people)
• Cross-functional Group
• Attempts to build a ”potentially shippable product increment” every
sprint
• Collaborates
• Self-Organizing
3. Scrum Master
• no managment authority of the team
• project management is split up among members
• Enforces time-boxing

21.  Scrum (the name is derived from an activity that occurs
during a rugby match) is an agile software development
method that was conceived by Jeff Sutherland and his
development team in the early 1990s.
 Backlog—a prioritized list of project requirements or
features that provide business value for the customer.
Items can be added to the backlog at any time (this is
how changes are introduced). The product manager
assesses the backlog and updates priorities as required.
 Sprints—consist of work units that are required to
achieve a requirement defined in the backlog that must
be fit into a predefined time-box (typically 1-4 weeks).
Mon, 13 Feb 2017 Aalborg University 21

22.  Demos—deliver the software increment to the customer so
that functionality that has been implemented can be
demonstrated and evaluated by the customer. It is
important to note that the demo may not contain all planned
functionality, but rather those functions that can be
delivered within the time-box that was established.
 Scrum meetings—are short (typically 15 minutes) meetings
held daily by the Scrum team. Three key questions are
asked and answered by all team members:
o What did you do since the last team meeting?
o What obstacles are you encountering?
o What do you plan to accomplish by the next team meeting?

27. A good user story uses the “INVEST” model:
 Independent. Reduced dependencies = easier to plan
 Negotiable. Details added via collaboration
 Valuable. Provides value to the customer
 Estimable. Too big or too vague = not estimable
 Small. Can be done in less than a week by the team
 Testable. Good acceptance criteria
