Agile

I am a little wary that “agile” appears to have become a morally loaded term. Despite some unhelpful dogma, the gradual shift towards developing software by iterative collaboration has been a universal “good thing”.

“Goldilocks” governance: balancing team autonomy and alignment for agile architecture

There can be a tension between the lean, experimental nature of agile development and the more deliberate, planned demands of a large organisation. It does not have to be like this.

If “Enterprise Architecture” is failing, what should architects be doing instead?

The discipline of architecture is an important part of any efficient engineering organisation. It just needs to adapt its game from the process-orientated “Enterprise Architecture” of old to something more collaborative and relevant.

Don’t use test coverage as a target

Code coverage can be a useful technique for discovering untested parts of your code base, but it makes for a useless target.

Why trunk-based development isn’t for everybody

There’s more to adopting trunk-based development than deciding to shun long-lived branches. You need a confident development team, a loosely coupled code base and efficient build automation to make it stick.

Agile metrics. You get what you measure. In a bad way.

Agile process tends not to generate the kind of metrics that management teams feed on. Should this be a problem?

The case against maturity models

Maturity models are a popular way of looking at development challenges. The problem is that they are an arbitrary and inflexible tool and they tend to encourage the wrong mindset.

Why SAFe can be agile kryptonite

The problem with SAFe is that you can implement it without writing a single unit test or automating a single build…scaled agile may be an oxymoron.

Should teams choose their own languages and tools?

Standardisation does have a place, but it should be reserved for infrastructure and collaboration rather than languages and tools.

How I learned to love the “Agile Industrial Complex”

There is a growing sense of unease around how larger organisations have implemented agile. In particular, there is a tendency towards centralised control that can be at odds with the agile preference for individuals over process.

Autonomous bubbles and event streams: Pragmatic approaches to working with legacy systems

It’s easy to get caught up in unrealistic notions that you can re-write a legacy system or gradually decompose it. There are other, more pragmatic approaches that can help to modernise architectures and enable new development.

Relax. There’s no conflict between architecture and agile.

Agile teams still need to make architecture decisions, but in supporting them architects should seek “just enough” architecture over “big design up front” and practical solutions over large-scale abstract thinking.

Can TOGAF and Agile really go together?

On the face of it, TOGAF describes a very different world to the agile preference for working software over documentation. That doesn’t mean that TOGAF is incompatible with agile, so long as you’re prepared to adapt its numerous building blocks.

Technical debt is an overused and lazy metaphor

Technical debt may be a useful metaphor for describing how bad code design undermines productivity to non-technical audiences, but it does not help in understanding the longer term problems that affect code bases.

What should a Scaled Agile “architectural runway” actually look like?

The Scaled Agile Framework talks about an “architectural runway” as the main deliverable for agile architecture, yet it’s vague on the detail of what this looks like.

How can Domain Driven Design help with large scale agile development?

Agile teams spend time modelling software whether they are prepared to admit it or not. Adopting a technique like Domain Driven Design can help to make this more efficient, particularly at scale.
