Systems - A Journey Along the Way Systems A Journey Along theWay Welcome to a journey in the realm of systems. The journey is still unfolding as this web site continues to evolve over time. Yet, even with the endless changes, there continues to be a connection, in one fashion or another, with systems.

Why I don’t agree that systems thinking is a ‘fallacy’ It’s been some time since I wrote my counterpoint to Bojan’s article on quitting GTD, and in that time I’ve come to know him a great deal better, to respect his opinion, and I consider him a friend. However when I read his latest post on the fallacy of systems thinkers I felt compelled to lay out the things I disagree with, and to defend what I see as my position as one of the ‘systems thinkers’ he refers to. Here’s the case for the defence: Exhibit A: The Review process ‘doesn’t work’ Bojan says that for the ‘majority’ of people, the review part of productivity systems is a ‘complete disaster’.

Fallacy of systems thinking and reversing the productivity game The problem with productivity enthusiasts these days, is that they will pay more attention to the hacks and tricks, than doing the actual work. We’ve created this “work masturbation” environment, where doing it better is more important than doing it at all. The problem lies with the saturation of the marketers in the field. They are creating all these artificial needs, like systems, and gadgets, in order to sustain themselves and their continuous work.

White Paper: Pragmatic Randomized Trials: Considerations for Design and Implementation - Evidera One of the challenges of designing effective PRTs is the choice of outcomes and endpoints. The term outcome is used here to mean a measured variable or event of interest (e.g., time to first occurrence of a composite outcome such as myocardial infarction [MI], stroke, or cardiovascular death, which collectively are referred to as major adverse cardiovascular events [MACE]), whereas an endpoint refers to an analyzed parameter that is expected to change over time as a result of an intervention (e.g., change in LDL-C from baseline). For a PRT to meet the requirements of both regulators and payers, it is important that the selected endpoints and outcome measures resonate with key stakeholders (patients, payers, regulators, and healthcare providers), and be defined with sufficient sensitivity (typically more important for safety) and specificity (typically more important for effectiveness estimates) to translate the trial objectives into precise definitions of treatment effect.

Complex systems science allows us to see new paths forward We’re at a unique moment in the 200,000 years or so that Homo sapiens have walked the Earth. For the first time in that long history, humans are capable of coordinating on a global scale, using fine-grained data on individual behaviour, to design robust and adaptable social systems. The pandemic of 2019-20 has brought home this potential. Never before has there been a collective, empirically informed response of the magnitude that COVID-19 has demanded. Yes, the response has been ambivalent, uneven and chaotic – we are fumbling in low light, but it’s the low light of dawn. At this historical juncture, we should acknowledge and exploit the fact we live in a complex system – a system with many interacting agents, whose collective behaviour is usually hard to predict.
