A bit of context

• Bonitasoft is a 7-year old company, founded by 3 technical experts in Java:

– Everything started with R&D– They once were in charge of:

• Product requirements• Design, Implementation• Quality• Pre-Sales• Usability, Documentation

– New actors and teams only took tasks (and control) away from them

10

A bit of context

• As Bonitasofters, we:– Are passionate human with substantial egos

-> involvement– Think we are quite clever

-> self-confidence– Like to enjoy ourselves

-> motivation– Are a little shy or…

-> Space for improvement

… have behavior preferences

– All pursue the same goal: create a product that rocks!11

A bit of context

• Common says about usability:

“Everyone has common sense.”

“UX is an optional polish on top of the technical base.”

“It is an additional constraint when time is short.”

12

A bit of context• With common sense: no UX person, no users involved

Formal specs Technical POC(feasibility) Working Alpha

Bad user

feedback.

⇒ Lots of rework after it’s delivered. Sad. Hurts egos.⇒ If developers code for someone else than themselves, they need UX

14

A bit of context

“We can all be part of UX, with a Usaband a Tech writer.”

“UX is an optional polish on top of the technical base.”

“It is an additional constraint when time is short.”

15

A bit of context

• Polish: UX people as a disastrous post-disaster relief– After the feature / product is developed– External consultant– An audit/validation, as the last testing suite.

Usability in an R&D Team

“We can all be part of UX, with a Usaband a Tech writer.”

“It’s a needed integrated layer of our piece of software.”

“It is an additional constraint when time is short. ”

19

• Usability in an R&D team• Reduce risk / improve value• Non-Negotiable Usability• To take away

• A bit of context

20

Usability in an R&D team

• UX person as an internal influencer– Why “influencer”?

• The difference between a shirt and a piece of software

Nice shirtTaylor

Useful and usable productDeveloper

Raw material Finished product

Nice fabricTextile worker

Clean, smart, bug-free codeDeveloper

Piece of software

21


• When influence is not enough:– UX design comes last in a thick roadmap:

• A new feature always start with technical feasibility⇒Feasibility of what? For what value?

– UX improvement comes last in a sprint planning:• New features and maintenance go first

⇒Some bugs are less critical than users getting stuck(Usability improvements have severity levels too)

⇒Usability debt

22


• UX person as a Silly Crusader vs Team Manager– “Release date is fixed”– “Other features are in the queue for this release”– “The time spent on the feature is enough”– “You cannot argue till you get to the perfect UX” – “You have to let go”

Just - Based – On – TimeRegardless – Of – The – Value – Delivered

LET GO ?!23


– Fight for UX.

– UX can become a person-to-person struggle24

• Reduce risk / improve value- Train


• A bit of context• Usability in an R&D team

25

Train

• UCDDD Corners (User-Centered Design, Development, and Documentation) 30 min sessions

- Pick a hot theme chosen by the team or the tech writer or the usab

- Give guidance and tips- Create quick tips and tricks & theoretical rationale

26

Train

• Simplified documentation guide

27

Train• Usability guidelines per topic

28

Train• Now in Google drive, migrating to Confluence

29

Train• Usability Principles• ISO 9241-11: Guidance on Usability. Interface and interaction

– User guidance, information structure, incitation– Help – Minimal workload, concision, low density– Consistency & standards– Visibility on the system status, feedback, waiting time– User control and freedom– Flexibility, variability intra-individual– Avoid errors and help error recovery, manage delete

⇒ Hard to translate into clear UI items⇒ Implementation depends on the context and the purpose

Train

• Users and developers share the cognitive schema and the principle that drive human activity

• But they are many elements of the system software use that the developers are not aware of

• A definition of activity

– Each situation is unique– The piece of software is just a part of the picture– Relationship to the piece of software: Bonitasoft has designed and

built the system – users haven’t 34

What Bonita BPM needs to do to let Dave use it

User-centered design

Techno-centered design

What Dave needs to do to use Bonita BPM Studio

• Bonitasoft needs to bridge the gap, not the users35

Train• User eXperience = make your

– Users, whoever they are– Succeed on all use-cases– Avoid and recover from error– Be efficient– Learn– Enjoy

⇒ Make R&D work worth it

⇒ Make the value real: create perceived quality⇒ Let Usab handle usability principles, work with her⇒ Let Tech Writer write the right articles and wording⇒ Developers learn/train as they go

36

Train

May include:1. The fact that there is an issue2. Its cause3. Its severity4. Its consequences5. What the user can do to recover6. Shortcuts on buttons

… in words the persona can understand

• Error messages

37

• Reduce risk / improve value- Wake up the craftmen / heroes


• A bit of context• Usability in an R&D team

38

Wake up the craftmen / heroes

• Facts:– 68% of users give up because they think you don’t care

about them– 50% development time is about fixing avoidable issues– 97% of users cite “ease of use” as the main factor in

selecting enterprise applications– By 2020, customer experience will overtake price and

product as the important brand differentiator

⇒ There is no other way than spend time on UX⇒ No code artist can manage ⇒ Need to turn into code craftmen

39

Wake up the craftmen / heroes

- Heroes’ qualities• Solid logic• Sense of responsibility• Empathy• Courage• Humility

• …. But no super-hero: not reading users’ minds

- Bonitasoft Marketing launched an external campaign

40

Craftmen / heroes… is not enough

“We can all be part of UX, with a Usab.It’s a needed integrated layer of our piece of software.It is a team purpose when time is short. ”

But time is still very short. So what?

41

• Reduce risk / improve value- Be creative


• Introducing Bonita BPM, Bonitasoft, R&D Bonitasofters• Usability principles

42

Be creative

• Solid logic, that’s what it is!⇒The team needs:

• Data from the field• Thresholds

⇒ Turn usability into a Boolean system:• Good to release / Not good to release• Feedback on non-negotiable items are bugs• No perfect UI. Good enough UI. Checked.

⇒That is Non-Negotiable Usability43


• A bit of context• Usability in an R&D Team• Reduce risk / improve value

44

Non-Negotiable Usability

• A goal:– The user needs to be successful to find value in

what we produce

• A team:– We want to build pride on what we release– We all play a part in this goal– We work with data from the field and thresholds

to avoid endless discussions and tension

45

Non-Negotiable Usability

• A process, methods, tools:

46

Process, Methods, and Tools

• A simplified checklist

UX = make your– Users, from the VIP personas– Succeed, on the basic use-cases– Avoid and recover from error– Be efficient whatever their “profile”

– Learn– Enjoy

47


• Translates into:– Users, from the VIP personas

• Create and know your personas, work with them, for them– Succeed, on the basic use-cases

• Get use-cases from them, and User Acceptance Criteria– Learn

• Easy to notice• Easy to guess the value• Easy to understand words, controls, flow

– Avoid and recover from error• Guidance• Clear, complete messages

• What is negotiable, in the end?– Efficiency, to be dealt with later on– More advanced use-cases, write tutorials until then– Graphical waows, yet another, fundamental job
