The Lost Art of Task Modelling - Agile in the City Bristol 2018

Updated for Agile in the City Bristol, November 2018
Task models are a simple, yet incredibly powerful, design tool. They help us to record user needs in a way that the whole team can work with, all the way from discovery to deployment and beyond. In the UX community, task models have been somewhat eclipsed by experience maps and service blueprints of late. I’m all for a juicy mapping exercise when I’m helping an organisation make strategic decisions. But what if the job at hand is the result of all that strategising: designing a website or an Alexa skill, say?

  52. 52. Eye of the Tiger by Survivor Risin' up, back on the street Did my time, took my chances Went the distance, now I'm back on my feet Just a man and his will to survive So many times, it happens too fast You trade your passion for glory Don't lose your grip on the dreams of the past You must fight just to keep them alive It's the eye of the tiger, it's the thrill of the fight Risin' up to the challenge of our rival And the last known survivor stalks his prey in the night And he's watchin' us all with the eye of the tiger Face to face, out in the heat Hangin' tough, stayin' hungry They stack the odds 'till we take to the street For the kill with the skill to survive It's the eye of the tiger, it's the dream of the fight Risin' up to the challenge of our rival And the last known survivor stalks his prey in the night And he's watchin' us all with the eye of the tiger Risin' up, straight to the top Had the guts, got the glory Went the distance, now I'm not gonna stop Just a man and his will to survive It's the eye of the tiger, it's the dream of the fight Risin' up to the challenge of our rival And the last known survivor stalks his prey in the night And he's watchin' us all with the eye of the tiger The eye of the tiger The eye of the tiger The eye of the tiger The eye of the tiger It's the eye of the tiger, it's the thrill of the fight
