Just give me a ball park? Yankee Stadium.


Two of my favourite estimation conversations (roles are indicative, not pointing fingers).

The What Is It?

Project Manager: "How long will it take you to test our disaster recovery solution?"
Me: "What's your disaster recovery solution?"
Project Manager: "We don't have one yet, but we need to test it."
Me: "I'm not convinced that is a valid approach."
Project Manager: "Well, what shall we do then?"
Me: "Create an disaster recovery solution."
Project Manager: "Can you do that?"
Me: "Yes."
Project Manager: "How long will that take to test?"
Me: "I don't know, I would be creating it, so I can't test my own work"

The Anything But...

Product Person: "Can you provide a forecast for how long these would take to implement?"
Me: "Are you asking for an estimate?"
Product Person: "Lets call it a gut feeling then. In days"
Me: "Is that different?" 
Product Person: "OK, I'll settle for a quote."
Me: "We may be straying into semantics here."
Product Person: "Just try and gauge it."
Me: "You know humans are rubbish at estimating time right?"
Product Person: "I know but I'm just asking for a projection."
Me: *sighs audibly*

As a heuristic, if this rings true:


Time spent generating estimates > Time spent doing the work

Then you should seriously have a think about estimating how long it takes to come up with an estimate. Mind the magical development unicorns sprinkling star dust on your product while you do. Or talk about alternatives to estimates as a means to gather information, try what success looks like, or a definition of ready. Break the cycle.

  1. My first thought, is that semantics are exactly what's needed in those conversations! Precisely because people rarely say what they mean (or even what they think they mean).

    1. A fair point, my usage is misleading in context there, as I think you are right, most of the time with estimates, the main problem is that people don't make their needs clear. Needs which usually have little to do with estimates!

A Lone Tester at a DevOps Conference

I recently had the chance to go to Velocity Conf in Amsterdam, which one might describe as a DevOps conference. I love going to conferences of all types, restricting the self to discipline specific events is counter intuitive to me, as each discipline involved in building and supporting something isn't isolated. Even if some organisations try and keep it that way, reality barges its way in. Gotta speak to each other some day.

So, I was in an awesome city, anticipating an enlightening few days. Velocity is big. I sometimes forget how big business some conferences are, most testing events I attend are usually in the hundreds of attendees. With big conferences comes the trappings of big business. For my part, I swapped product and testability ideas with Datadog, Pager Duty and others for swag. My going rate for consultancy appears to be tshirts, stickers and hats.

So, lets get to it:

Inclusiveness - there was a huge focus on effective teams, organisational dynamics and splitt…

Wheel of Testing Part 2 - Content

Thank you Reddit, while attempting to find pictures of the earths core, you surpass yourself.
Turns out Steve Buscemi is the centre of the world.

Anyway. Lets start with something I hold to be true. My testing career is mine to shape, it has many influences but only one driver. No one will do it for me. Organisations that offer a career (or even a vocation) are offering something that is not theirs to give. Too much of their own needs get in the way, plus morphing into a badass question-asker, assumption-challenger, claim-demolisher and illusion-breaker is a bit terrifying for most organisations. Therefore, I hope the wheel is a tool for possibilities not definitive answers, otherwise it would just be another tool trying to provide a path which is yours to define.


In part one, I discussed why I had thought about the wheel of testing in terms of my own motivations for creating it, plus applying the reasoning of a career in testing to it. As in, coming up with a sensible reflection of real…

What if information isn't enough?

One of my aims for this year has been to attend/talk at what I will class for the purposes of this blog as 'non-testing' events, primarily to speak about what on earth testing is and how we can lampoon the myths and legends around it. It gets some really interesting reactions from professionals within other disciplines.

And usually those reactions (much like this particular blog), leave me with more questions than answers!

Huh?

After speaking at a recent event, I was asked an interesting question by an attendee. This guy was great, he reinvented himself every few years into a new part of technology, his current focus, machine learning. His previous life, 'Big Data', more on that later. Anyway, he said (something like):

'I enjoyed your talk but I think testing as an information provider doesn't go far enough. If they aren't actionable insights, then what's the point?'
This is why I like 'non-testing' events, someone challenging a tenet than has be…
