So, we’ve all heard of The Marshmallow Test, right? This is where children are tested on their ability to resist one marshmallow on the promise of getting two marshmallows later (a level of self-control that even as an adult I find a challenge!).
But what about the Other Marshmallow Test?
This is a game I conceived to illustrate the benefits of limiting work in progress – given as a talk at Agile in the City.
The initial premise is about efficiency – can we complete our work faster (or consume our marshmallows more quickly) when doing it one piece at a time, or by multi-tasking? In itself it’s an interesting question, and in the game the answer often depends on the individuals who have volunteered and how much they enjoy marshmallows. There is so much more to observe when you try this out though, such as the impact on stress levels, managing risk, delivering value etc. You can download the slides here to get the full story.
The best thing about the game is that it shows just how far the concept of limiting work in progress applies to any work environment – this is not just about software! Upon seeing the game played in a lightning talk, a member of our legal team considered whether this could help them deal with the barrage of requests they get from all directions. An invitation to visit his team swiftly followed.
We played the game, talked about flow, and then I left them with Kate Sullivan’s talk about agile adoption within the legal team at Lonely Planet. A couple of weeks later I strolled by to witness the joy of a stand-up around a kanban board.
We talked about the benefits they were experiencing, as well as some of the challenges remaining. They still have things to improve (we all should continuously improve, after all) but they were finding a lot of blockers removed simply by visualising and verbalising them together. You can read more about how they have decided to apply agile in a post written by John Halton (Assistant GC) for Practical Law.
Learning at FT
One of the things I love about working at the FT is seeing teams from across departments learn from each other. Just as our legal team have learnt about agile from technology; our product and tech teams have learned a lot about how to use KPIs from our commercial teams; our editorial teams think more about reader engagement with help from our analytics teams; and here in engineering we continually exchange new lessons with every department we work with.
Moving to Continuous Delivery and a Quality Focused Process
We’re all familiar with the waterfall approach of software development. It keeps skill-sets in silos and, from a tester point of view, we were the ones squeezed for time when projects overran.
Adopting agile in the latest Membership Programme incarnation at the Financial Times many years ago started to make a change. The concept of starting to break work into smaller pieces and working much closer to one unit as a team removed the big bang approach of these problems. Ultimately they still existed. Like most development teams our testers were outnumbered by developers, but ultimately had as much if not more to do. The introduction of automated testing if anything made matters worse. When you’re new to agile you can struggle to work out where to build automated tests into the process. We agreed that they needed to be part of the sprint from day one, but this meant we still had split skill-sets – manual and automated testers. Both were needed to get the work done.Continue reading “Removing the Tester Safety Net”
In August 2016 the FT switched from on-premises Splunk to Splunk Cloud (SaaS). Since then we have seen big improvements in the service:
Searches are faster than ever before
Uptime is near 100%
New features and security updates are deployed frequently
One interesting new feature of Splunk Cloud is called HTTP Event Collector (HEC). HEC is an API that enables applications to send data directly to Splunk without having to rely on intermediate forwarder nodes. Token-based authentication and SSL encryption ensures that communication between peers is secure.
HEC supports raw and JSON formatted event payloads. Using JSON formatted payloads enables to batch multiple events into single JSON document which makes data delivery more efficient as multiple events can be delivered within a single HTTP request.
Time before HEC
Before I dive into technical details let’s look at what motivated us to start looking at HEC.
I’m a member of the Integration Engineering team and I’m currently embedded in Universal Publishing (UP) team. The problem that I was recently asked to investigate relates to log delivery to Splunk Cloud. Logs sent from UP clusters took several hours to appear in Splunk. This caused various issues with Splunk dashboards and alerts, and slowed down troubleshooting process as we didn’t have data instantly available in Splunk.
At the Financial Times we’ve recently released a new version of our website, FT.com. “Next FT”, as we’ve come to know it, is now the default experience for our users, and so far it’s proving to be a great one: It’s faster, it’s nicer, it’s better; a success across the board . Yet there’s an aspect of our new site we have largely overlooked: accessibility (a11y).
In this post we will explore what web accessibility is, why it’s important, the current state of accessibility at FT.com and the work we’re doing to improve it.
Approximately a year has passed since Salesforce announced the new Lightning experience. And what a year for Salesforce! At first I thought ‘this is going to take a while, there’s going to be a learning curve, probably known bugs to deal with’, we tentatively started switching on the New Lightning Experience to play around with the new User Interface. In a short while we tested some visualforce pages embedded in the new Salesforce application. Finally, this summer we made the leap to building the first Lightning components and Lightning application.
One of my favourite series as a child was ‘The Flash’. He could miraculously find himself from his home dressed in pyjamas, down the street in front of a shop window within seconds. When I built my first Lightning app this year, the images from ‘The Flash’ running around with the speed of light immediately came to my mind. Three words: fast, simple, beautiful. No wonder they named it Lightning.Continue reading “The Year of Lightning”
“The game centres on a model of a donkey named “Roo” (or “Buckaroo”). The mule begins the game standing on all four feet, with a blanket on its back. Players take turns placing various items onto the mule’s back without causing the mule to buck up on its front legs, throwing off all the accumulated items.” – Wikipedia, Buckaroo!
