Goldilocks is an interesting technique and basically doing the opposite of estimating: You shape the work into the desired sizes.
- Vote each item into one of three piles: “Too Big”, “Just Right”, and “Too Small”.
- Split any “Too Big” items into “Just Right”-sized ones.
- Group any “Too Small” items together into “Just Right”.
The Goldilocks Principle applied to sorting stories reminds of potato grading machines that sort potatoes into different sizes.
Enjoy the flow.

A Big Visible Two-Day Agenda is an excellent visual reference for a training, workshop, or conference.
Each half day is based on a simple 3 × 3 grid with a title. Key:
- Pink—game or exercise.
3″ × 5″ Post-it notes cut into 3″ × 1¼″ strips allow for a landscape text that fits nicely in one of the nine cells. It is easy to move the contents around.
The day before, you can prepare the whole to save time setting it up at the site:
- use sheets of A4 paper with the grid and small Post-it strips;
- prepare four flip charts in landscape orientation with the grid structure—one flip chart accommodates morning and afternoon, each with a 3 × 6 grid;
- prepare the full 3″ × 5″ Post-it notes; you can even already stick them on the flip chart; they might curl up a bit, though.
At the site, stick the four flip charts to the wall, and the Post-it notes to the flip charts.
- Simple, clear purpose and principles give rise to complex and intelligent behavior.
- Complex rules and regulations give rise to simple and stupid behavior.

From team charter:
- Team—A group of people or animals linked in a unity of purpose.
- Self-organization—The tendency of an open system to generate new structures and patterns based on its own internal dynamics. Organization design emerges from the interactions of the agents in the system; it is not imposed from above or outside. Facilitating Organization Change: Lessons from Complexity Science
Three factors influence the patterns that emerge:
- The container sets the bounds for the self-organizing system. It defines the “self” that organizes.
- Significant differences determine the primary patterns that emerges (power, level of expertise, gender, …).
- Transforming exchanges form the connections between system agents.
Just as a person needs time and space to incubate thoughts before a new Idea can emerge, a system needs a bounded space for the emergence of new patterns. Patterns imply structure, organization. Self-organizations gives you order for free. Effortless organization? don’t just do something, stand there!
Life is a serious game. life is a broccoli.
The 7th Key Principle of Lean Software Development is Optimize the whole.
The burning question is, how to boost collective evolutionary power from a participative, co-creative agile organizational point of view? Large Scale Intervention (LSI) provides principles, patterns and practices to just this? LSI is also known as Whole Systems Change.

Highlights from Past the Tipping Point: The Persistence of Firefighting in Product Development by Nelson Repenning, Paulo Gonçalves, and Laura Black.
Putting out fires is not improvement. Finding a point out of control, finding the special cause and removing it, is only putting the process back to where it was in the first place. It is not improvement of the process.
—W Edwards Deming
Unplanned allocation of resources to fix problems can switch the entire company to epidemical firefighting and organizational pathology. Even a temporary increase in workload can initiate the firefighting dynamic and cause a permanent decline in system performance and health.
- snaps into place when pushed beyond the tipping point or threshold
- drives out disciplined and more structured (development) processes, becoming the (development) process instead
- can significantly degrade an organization’s ability to create high quality products in a stable, predictable, sustainable and resilient way
- is a self-reinforcing syndrome with a tipping point, and is, therefore, fragile
- is hard to recognize (its symptoms), causing corrective action to be taken too late
- comes very naturally
- be an innovative, competitive, stable, predictable, sustainable and resilient organization;
- stay clear of the tipping point when you are on its productive and innovative side;
- get close to the tipping point a.s.a.p. when you are in firefighting mode, and then nimbly nudge it over;
To avoid firefighting to become a company-wide disease:
- Discourage, ignore or penalize heroism and heroic behavior.
- Use a boom buffer with a clear policy and managerial impact when excepted.
- Keep current tools and technology, avoiding time needed to invest in learning them that (temporary) lowers productivity
- Have a laser focus on top quality for product, process and people as lower quality will push the organization into the death spiral of declining competitiveness, reduce revenue and future innovation.
- Do root cause analysis and resolution of the top problems. Just postponing problematic projects does not prevent the spreading of firefighting, it just pushes them downstream to bite you next year, and probably harder.
- Perform aggregate resource planning to prevent fires.
- Reduce the number of parallel products or projects—so bring focus.
- Avoid full utilization of human assets. Cherish slack resources as a buffer against uncertainties (also see boom buffer).
- Aggressively cancel failing projects early.
- Revisit the product plan instead of trying to catch up.
- Do not rent or steal people from or lend people to other parts of the organization as it might start a fire.
- Reduce workload effectively to stabilize the system, e.g. by skipping a model year altogether.
- Do fewer projects and cancel more.
- Put a strict (Work In Progress or WIP) limit on many or all parts of the value stream, and use those to maximize flow.
- Undercommit and overperform.
- Uphold a strict policy of only accepting finished, done work. Mercilessly reject any unfinished work and loose ends.
- Perform thorough up-front work. Make policies and admission criteria to pull something into the next step crystal clear. This will:
- increase the likelihood that the item will get done in time;
- reduce or avoid the need to cancel it later;
- make owners face strong incentives to invest in the early phase activities and develop clever ways to demonstrate the efficacy of a proposed product far in advance of its detailed design.
All this resonates with agile, scrum, lean, and kanban.
Scrum has much ado about Definition of Ready and Definition of Done.
The Definition of Ready for the current phase equals the Definition of Done for the previous. Likewise, the Definition of Done for the current phase equals the Definition of Ready for the next. They are the two sides of the same membrane.
So, why not simplify it and talk about the membrane only?
