Projects and development teams are struggling with poorly designed systems, with many developers dedicated to patching systems just to keep them alive. Largely the software development culture is broken, Vaughn Vernon claimed in his presentation at the Domain-Driven Design Europe conference earlier this year, talking about problems he has encountered but also about solutions to these problems.
Microservices and Domain-Driven Design (DDD) are not only about Bounded contexts, although a fundamental tool for defining granularity of microservices there are other important concepts as well. Correspondingly DDD is just not about entities and repositories, Michael Plöd claimed in his presentation at the recent microXchg conference in Berlin showing how DDD can be used creating microservices.
“It’s Not Just Microservices”: Fred George Discusses Technology, Process and Organisation Inhibitors
At the microXchg 2016 conference, Fred George presented “It’s Not Just Microservices”, and argued that microservices can enable an organisation to ‘go faster’ and rapidly deliver business value. However, the implementation of microservices alone will not lead to success, and inhibitors to increasing business agility within the context of technology, process and the organisation must be removed.
Kelsey van Haaster will give a talk at 1st Conference about how to develop a road map to agile fluency for teams and organisations. InfoQ interviewed her about the possible ways to do an agile fluency assessment, example of findings and improvement opportunities that came out of the assessments and things that she learned, and advice for readers who want to use the agile fluency model.
Software industry pioneer, prolific author, researcher, consultant and photographer Edward Yourdon died on January 20, 2016
User Story Mapping can be a simple yet valuable pattern when adopting Domain-Driven Design (DDD) in projects dealing with complex domains. It can help creating shared domain knowledge among developers and domain experts, Eriksen Costa claims in a blog post discussing advantages combining User Story Mapping with Domain-Driven Design (DDD).
Moving from a monolith to microservices the only value business stakeholders care about is reducing cost. It will not increase or protect revenue and neither scaling nor distribution are good reasons that will convince the business, Ian Cooper claimed in his presentation at this year’s Microservices Conference in London describing guidelines moving from a monolith to a microservices architecture.
InfoQ interviewed Stefan Roock about adding XP practices to Scrum, why using an agile framework as a blueprint for designing the organization is a premature optimization and why culture and principles are more important than practices. Roock also explains the agile scaling cycle with examples of how it can be used, and talks about the benefits and pitfalls of this approach for agile scaling.
An interview with Nicole Forsgren about why organizations are starting to embrace DevOps methods, how being able to deploy fast can also increase IT stability, what to focus upon when changing the organizational culture to improve performance, how lean management can help to increase the performance, and asked her for advice when organizations want to apply DevOps to increase their performance.
Agile testers can signal and question the (testing) process. Marnix van den Ent gave a talk at the Agile Testing Days 2015 in which he explained how he views testers as a harlequin: "a servant to the team and its process, like the Italian Harlequin he is there to help to understand what is happening". An interview about developing an art of questioning, XP practices and retrospectives.
Uncle Bob proposes an oath to software programmers as other professions have, considering the importance of this craftsmanship.
Enterprise Services Planning is a way of planning, scheduling, sequencing, and selecting work for professional services. It extends Kanban for enterprise-wide service improvement. InfoQ interviewed Anderson about what Enterprise Services Planning (ESP) aims to deliver, how it can be used to manage risks, how cost of delay can be used inside ESP, and why feedback loops are important in ESP.
Dotty, a platform aimed to develop new technology for Scala tooling as well as try out new concepts for future Scala versions, has reached bootstrap status. This means that its compiler is written in Dotty and can compile itself, thus providing a drop-in replacement for the original one. InfoQ has spoken with Dotty major contributor Dmitry Petrashko.
Obeya is a management approach that uses war rooms and visualization for managing projects. InfoQ did an interview with Malika Mir about why she decided to implement Obeya, how they are using Obeya to manage project portfolios, their experiences with Obeya and the benefits that they have got from it.
Eventual consistency is a design approach for improving scalability and performance. Domain events, a tactical element in Domain-Driven Design (DDD), can help in facilitating eventual consistency, Florin Preda and Mike Mogosanu writes in separate blog posts, each describing the advantages achievable.
