Remove waste from the UxD process
Too much too often product (software) design and development is document-driven. With the agile manifesto and principles in mind, we want to focus on creating great and valuable products (software) and releasing these early and often to get valuable end-user feedback, in order to improve our products (software) iteratively and incrementally.
Forget about the overload of UxD deliverables that are created to communicate “specifications” to “developers”. Re-consider and only create those deliverables that truly serve a purpose. We value “making” over “analysis“; we value “building” over “specification“. Lean helps us to focus on flow and to reduce non-value creation (waste).
What do I mean?
Useful deliverables (depending upon your context):
- Branding and styleguide (by preference a living styleguide, to minimise maintenance effort)
- Low-cost prototypes used in user testing
- Low-cost sketches, mock-ups, designs, etc
- Detailed User Interface specifications (for example including annotations of every screen)
- Wireframes of every screen, every screen size
- Visual designs of every screen
- High-fidelity mockups (not reused in development)
Try to minimise the “upfront” creation of large UxD deliverables to be handed over to developers, instead rely on true cross-functional collaboration.
True cross-functional collaboration (including designers, including UX people, including usability engineers, including developers, including product owners, including business stakeholders, marketeers, etc). True agile cross-functional collaboration is the foundation and the catalyst for collaboration and short development / release cycles. Agile re-focuses product (software) development on value creation and working products (software).
In every step of the cycle, and from the very beginning, the whole team is involved. The whole team approach aims to create a shared understanding with everyone, all the time. Knowledge, user feedback can be quickly spread and shared, and the team minimises the need for handovers (in any form: documents + interpretation, pass-through communication, re-discussions, etc).
Apply the scientific method
BUILD > MEASURE > LEARN
MAKE > CHECK > THINK
The scientific method exists for centuries and we are simply applying it to nowadays product (software) development.
In Lean Startup this is known as the build > measure > learn cycle. This is an on-going process, it obviously doesn’t stop with 1 iteration. We also call this make > check > think.
The only way to create products (software) which matter for your end-users, which mean a difference, which serve their needs is:
- by first focusing on outcomes (objectives) and next on features (solutions)
- by getting in touch with your end-users, observe and measure how they use your products
- by focusing on creating valuable experiments to expose risks and uncertainty
- by improving whatever you’re making based upon that feedback
- by building upon collective knowledge and wisdom and let the whole team flourish in creating the best experience
- by creating products iteratively and not only incrementally
- by minimising the total time going through this process
- by creating an environment of continuous learning

A few articles
“Cross-functional” collaboration in (agile) product development means that the whole (complete) product “development” team is participating. Scrum talks about a “development” team without distinction of role. As such, “developer” means any competence or skill required to create the product or service, not limited to “programming” (writing code).
Lean UX heavily promotes the whole product development team participating during the complete product development cycle from the very beginning. The entire team approach aims to create a shared understanding with everyone (all team roles) from the start and to minimize any waste originating from working in sub-teams or silos (hand-overs, intermediate deliverables, re-discussing the same topic with people who didn’t participate, etc.).
True agile teams (feature teams) are product-oriented and can implement product features end to end, creating value pieces with every item done. Collaboration with all team members is an excellent source of creativity, new ideas and innovation. This kind of cross-functional collaboration is demanding: people are expected to think outside their box, participate in work outside their main domain, and help create that necessary shared understanding to deliver value within an iteration.
Teams working in a phased approach (the so-called staggered sprints) face several worries – this should not be accepted as standard, and such teams should strive for a better working method. A phased approach is some work done in a sprint before the “development” sprint (or even worse, acceptance or testing after the” development” sprint).
The challenges with this phased approach are:
- Sprints become out of sync
- Iteration without agility
- Lack of ownership amongst the developers
- Waste (hand-overs, intermediate deliverables, etc)
The (single) (proper) Scrum team approach has numerous benefits:
- Understanding of concepts and users’ needs amongst all team members
- Improved time to deliver (precondition is to deliver chunks of value you are able to implement within a sprint)
- Less re-work, less waste
- Improved definition of done
- Sense of ownership amongst all team members
And so, we urge you to re-consider any extensive upfront work (before “construction”) and try to create shared understandings with the whole team. That shared understanding will lead to a willingness to collaborate within the same sprint truly. You foresee a regular cadence of user tests in the Lean UX approach. The aim is to create a “test everything” culture: we test what’s available, and given the users’ feedback, we improve (we iterate).
