Antifragility

The history of antifragility

Black Swan events.

A Black Swan event is defined by Taleb as: “…the Black Swan problem – the impossibility of calculating the risks of consequential rare events and predicting their occurrence. ”

The concept of being antifragile

The idea of being antifragile is to be the opposite of fragile. The fragile items or systems break when they are mishandled. The antifragile wants to be pushed, it wants to receive impacts and chaos, that is the way it learns and improves.

for a system to not only withstand or endure chaos, stress and high-impact events but to improve and upgrade itself. By looking at a system to be antifragile it adapts to the surroundings, and it is here that the antifragile system changes from the robust system. The robust system can withstand high-impacts and will not break when negative scenarios happen but neither will it take in the possitve impacts or scenarios, it will never improve before the whole system is changed. The antifragile system learns from the impacts, negative and possitive, and thus becomes stronger with each hit it takes.

The antifragile loves randomness and uncertainty, which also means— crucially— a love of errors, a certain class of errors.

To understand and use the aspects of antifragility it is important to remember it is the opposite of fragile. The chaos has to be around an hit the antifragile system or else it will not improve.

The concept of antifragility is developed by Nassim Nicholas Taleb and discussed in his books, Fooled by Randomness, The Black Swan and Antifragility. In his book Antifragility, Nassim Nicholas Taleb talks about the idea and thoughts of the antifragility.

Defenition of antifragile:

Some things benefit from shocks; they thrive and grow when exposed to volatility, randomness, disorder, and stressors and love adventure, risk, and uncertainty. Yet, in spite of the ubiquity of the phenomenon, there is no word for the exact opposite of fragile. Let us call it antifragile. - Nassim Nicholas Taleb

"At the core of antifragility is the conviction that planning is, to a large extent, futile, as unforeseeable events keep destroying our carefully laid out plans and detailed schedules."

Recall that the fragile wants tranquility, the antifragile grows from disorder, and the robust doesn’t care too much. - Nassim Nicholas Taleb

Crucially, if antifragility is the property of all those natural (and complex) systems that have survived, depriving these systems of volatility, randomness, and stressors will harm them. They will weaken, die, or blow up. - Nassim Nicholas Taleb, Fooled by Randomness

something that is robust merely tolerates adverse or unexpected conditions, whereas something that is antifragile thrives—its performance actually improves. - Robert W. Lucky, Antifragile Systems

The antonym of “fragile” is not robustness or resilience, but “please mishandle” or “please handle carelessly,” using an example from Taleb when referring to sending a package full of glasses by post. - Terje Aven, The Concept of Antifragility and its Implications for the Practice of Risk Analysis

‘Fragility’ can be defined as an accelerating sensitivity to a harmful stressor: this response plots as a concave curve and mathematically culminates in more harm than benefit from random events. ‘Antifragility’ is the opposite, producing a convex response that leads to more benefit than harm. - Nassim Nicholas Taleb, ‘Antifragility’ as a mathematical idea

Using the antifragile system in Project, Program and Portfolio Management

Starting a new project has a great deal of unknown and "has a posibility to happen" scenarios. In the first steps of planning the project, the project manager might have done a Gantt Chart, a Stage-Gate Model, an FMEA analysis and used other planning and risk tools for planning the time line and the steps of the project. Using these tools create a more robust project but events will happen, some foreseen and some might suddenly hit and create an unwanted situation. Therefore a very important and often occurring (also reoccurring) event for manager of projects, programs and portfolios are dealing with risk and the uncertain aspects of when or how something will happen . Protecting their projects and making them able to respond to threats and survive the negative events is a big part of managing projects, programs and portfolios. Here the antifragile system enters the picture.

An antifragile system thrives in disorder and with stressors. Therefore the antifragile system is the ideal match for venturing out into the unknown. It is important to note however that being antifragile does not solve all solutions and antifragility is an idea and a state a project can be in, it still requires planning, errors, and a lot of learning by doing (maybe even burning) to keep the antifragile system afloat.

Implementing the antifragile idea

When working with Project, Program and Portfolio Management the implementation of the antifragile concept can be difficult to handle. There is as such no list to follow on how to make an antifragile system, being antifragile is a state the system is in when outside actions and impacts have a positive effect on the system.

In order to work towards being antifragile the article Complexity management for projects, programmes, and portfolios proposes 5 rules to follow:

• Rule 1: Think of projects as human bodies, not machines.
• Rule 2: Create project portfolios that can collectively learn from the others' mistakes.
• Rule 3: Small projects and project teams are efficient.
• Rule 4: Fail often, fail cheaply.
• Rule 5: Project managers must have real skin in the game.

The 5 rules can be used by managers to work towards becoming more antifragile.
