Safe-to-fail experiments can be used in complex environments to probe, sense, and respond. You have to know what success and failure look like and need to be able to dampen or amplify the effect of probing to handle potential failures. Safe-to-fail experiments can help you to deal with risks and uncertainty, learn, and keep your options open.
Lean IT should help to simplify and improve the way we create value for customers and develop better solutions for tomorrow. Organisations of the future will focus on horizontal product or service streams- and everything else, including experts and managers, is there to enable the front-line to do their work right-first-time-on-time, with no hassles.
Complex AI systems with non-deterministic outcomes pose challenges for testers and programmers. Such systems will increasingly become normal in high-impact, high-risk applications, argues Fiona Charles; testers should increase their capacity for thinking and learning and develop a number of personal strengths such as courage and good judgement.
Honeycomb is a tool for observing and correlating events in distributed systems. It provides a different approach from existing tools like Zipkin in that it moves away from the single-request-tracing model to a more free-form model of collecting and querying data across layers and dimensions.
The Software-Centric Systems Conference explored new technologies, trends, and experiences in developing complex software systems. InfoQ spoke with Rob Howe and Martijn Rutten, two members of the program committee, about the main challenges that software development is facing, technology developments, driving innovation, and deploying agile to improve process reliability and deliver value.
Thomas Bradford talked about his experience with maintaining a monolith Java based system with zero test coverage and large technical debt at the Agile Testing Days 2015. InfoQ interviewed him about the problems that they had maintaining the system and the technical debt that had been build up, why they decided to take a different approach and how they improved team morale.
Russ Olsen did the opening keynote titled "To the Moon" at the GOTO Berlin 2015 conference. InfoQ interviewed him about drawbacks of doing all the things at the same time to meet the deadline, learning from things that went wrong and from things that went right, how little things can kill you in software development, and how to focus and deal with details when doing complex work.
Should you rebuilding or refactoring software?An interview with Wouter Lagerweij about what it is that makes refactoring so difficult, if rebuilding software is less risky than refactoring, and how continuous delivery fits with rebuilding software.
InfoQ interviewed Frank Penning, PMO manager from Philips Lighting, about the main challenges that Philips Lighting is facing in product development, why Scrum is not enough, how they apply SAFe, and the benefits that they have gained from deploying agile methods for product development.
Making teams working together can be challenging, but it is often needed to develop and deliver large complex products. In her opening keynote about scaling dilemma's at the Agile Adria 2015 conference Mary Poppendieck presented ideas for organizations that want to scale agile.
At Craft Conference 2015 in Budapest, Mary Poppendieck discussed the ‘new software development game’ and offered advice on how best to utilise containers, microservices and consumer-based contract tests to lower friction and limit risk within software systems.
Behavior Driven Development (BDD) uses examples, preferably in conversations, to illustrate behavior. A lot of people focus on the tools if they are doing BDD but having the conversations is more important than writing down conversations and automating them said to Liz Keogh. An exploration of using BDD to do experiments to deal with complex problems and do discoveries.
InfoQ did an interview with Gil Zilberfeld about managing the expectations that organizations have of agile and how to prevent misconceptions, valuable ideas and practices from agile and what the future will bring for agile.
The starting keynote at Velocity Conference Europe 2014 was all about how human error is too often the easiest way to explain away a failure and how a different approach is needed. Steven Shorrock, European Safety Culture Programme Leader at Eurocontrol, explained why a Systems Thinking approach applied to safety is a better answer.
To thoroughly remove waste in a process you need flow to deliver just in time, and mindfulness and situational awareness in organizations to handle problems with processes and built in human intelligence. Organizations apply concepts from flow to develop what is needed and when it is needed and use pull to prevent inventories. What they also need is “Jidoka”: mindfulness and situational awareness.
