Complaining is like releasing gas.

It’s a natural occurrence. Everyone does it.

But no one wants someone else to do it next to them.

We all complain. I believe branding this behaviour as a binary concept like “good” or “bad” rather than evaluating it in a spectrum doesn’t help at all.

Because both extreme ends of this spectrum harm trust. Acting like we are sublime creatures who never complain fosters artificial harmony and politics in the environment, which can easily turn into an impediment against transparency. …


As described by Neil deGrasse Tyson, an influential American scientist, it can be argued that there are three categories of truths: Personal, political and objective truths.

The beautiful thing about the objective truths is that they are established by evidence. Not by faith or incessant repetition. They are observed, experimented and measured.

Neil DeGrasse Tyson explains the importance of objective truths

These objective truths can offer insights about “why” and “how” some approaches usually help us get better results than others.

In this short post, I’ll introduce an objective truth that resulted from a scientific study and that could explain…


Regardless of the framework chosen, any iterative and incremental product development approach can be reduced to one goal: Creating a working product in short cycles.

A working product is “Done”. Done means “there is nothing left to do”.

“There is nothing left to do” implies that the result of the work is in a state that can be used by the end-users when released. Not only does it address the core functionalities but it also includes all performance and security-related concerns.

Ken Schwaber, co-creator of one of the most popular frameworks to deal with complex problems, explains it here crystal…

Treacherous bottlenecks can nullify all your hard work, no matter how industrious you are.

Have you ever wondered where “bottleneck” term comes from? Let’s try to understand it a bit better.

Imagine you have a bottle of water and your goal is to empty it as quick as possible.

Scenario 1: You overturn it, the water runs out by itself, and it’s done.
However, you realise that the bottle neck (literally the narrower part of the bottle) limits the flow speed of the water.

It makes you wonder…

Scenario 2: So you decide to get another bottle of water. Identical. You overturn it, but this…


As a servant leader, a Scrum Master focuses on the needs of others, before her/his needs.

“Reveal, not resolve” mentality plays an important role in this context. Because any time the Scrum Master steps in and takes action on behalf of the team, this may create two negative impacts:

  1. The team may lose an opportunity to self-organise, learn & grow together.
  2. Scrum Master’s solution may turn out to be a premature solution that’d cause even more problems in the future (Today’s problems come from yesterday’s solutions, one of the 11 Laws described in Fifth Discipline).

As a result, the Scrum…


Suppose you run a bakery. You bake some of the finest cupcakes in town.

A customer walks into your store and says, “I want a cupcake with chocolate flavour, royal icing, a cherry on top and in brown wrapping, please”.

You write the details down and send it to the kitchen. Then the chef bakes a cupcake against these requirements.

However, would you serve this cupcake to your customer without satisfying the below criteria?

  • Customer confirmed they are not allergic to any of the ingredients
  • All ingredients are fresh and edible
  • The product/kitchen environment comply with the FSA (Food Standards…

“He puts everything in place to get the ball up to the final third of the pitch and then trusts his team to finish the job in the only area of the field that can’t be planned for.

This is how Thierry Henry, the legendary French striker, describes the football mentality of his former coach in F.C. Barcelona, Pep Guardiola.

F.C. Barcelona will probably be best remembered for the period they dominated the competition in the late 2000s and early 2010s. …


It’s 9:30 am.

The Scrum Team gathers around their team desk to hold the Daily Scrum.

Jamie, one of the team members, highlights a problem that he faced yesterday:

“I cannot deploy the code into the staging environment due to pipeline issues.

I need help from the infrastructure team.

I raised a ticket, but since they had so many things in the queue, it’s not been prioritised yet.

Daniella, could you help us remove the impediment?”

Daniella is their Scrum Master. She’s a new member of the team. …
