Agile Estimator

Test Coverage with Pytest

Code coverage is a measure of what percentage of lines of code are covered by a test, identifying the unused conditional branches and lines.

Book Review

Review: The Goal

Having read both the Phoenix Project and The Dev Ops Handbook, which both reference The Goal, I felt I had to read the book that was the inspiration.

Docker Compose

A production deployment requires a working database. Docker Compose can set up both the database and application in one step.

Flask Blueprints

We will add configuration to the Agile Estimator application, allowing us to run it in dev, test or production modes, and introduce Flask Blueprints.

Introducing a Database

Most applications are backed by a database. In this post we will start to add a database to the estimator application using SQLAlchemy to access the data.

Dev Ops

Mob Programming

At a recent Dev Ops conference , I heard the term mob programming for the first time. There do not appear to be too many people doing this at the moment.

Agile Estimator

Flask and Docker

Getting an application from development servers into production can often be an afterthought for developers. Use Docker from early on to ease this step.

Agile Estimator

Flask with Rest

This post continues the development of an application using Flask. Today we will add some Rest endpoints to the anonymous estimator.

Introduction to Flask

Flask is a Python framework for creating lightweight web sites and API endpoints. This post is about my first experience using Flask.

Dev Ops

Test Automation

A Dev Ops operating model shows its best qualities when most testing is done automatically. Remove exploratory testing by replacing it with automated testing.

Dev Ops

Lead Time

Lead time is how long it takes to get an idea into production, fully supported by operations. How can Dev Ops thinking reduce this time to the minimum?

Dev Ops

Production Support

Developers like to develop new things. Having to deal with users who raise pesky bugs is not what they signed up for. Culture is key to good production support.

Dev Ops

Feedback

Different skils are needed to build software. When quality is low as work passes down the line, problems build up. Feedback is the key to exposing issues.

Book Review

Review: The One Thing

Learn how to break down your goal so that the first step is clear by reading The One Thing: The Surprisingly Simple Truth Behind Extraordinary Results.

Dev Ops

Refreshing Data

Most applications require a database to support the code. Developers should run their code against production like database to fully test their code.

Dev Ops

Focused Teams

A focused Dev Ops team that sits together focusing on one priority will deliver quality, value-add software, with low lead times, and high user satisfaction.

Dev Ops Transformation

Transformation to a Dev Ops operating model can allow our company to deliver high quality software and systems quickly, at high speed, using reuse to achieve cost savings at a group level.

Coding With Children

Spelling Game

In this post I outline a spelling test game that I want to build with my children to introduce them to some programming concepts.

Agile

Spikes for Analysis

The approach most Agile teams use to get analysis done is to use a task called a spike. This allows a team member to do some deep dive work to prepare a user story.

Agile

Backlog Grooming

To meet the Definition of Ready, most users stories require a lot of analysis to be completed. Team members need to understand the requirements and they will measure success. Backlog Grooming (also called refinement) is the process of getting the story ready.

Coding With Children

Coding With Children

Programming skills are becomming more and more a part of normal life, and future generations will need to understand and use the basics of computer code or face a major handicap. I want to introduce my own two children, a seven year old girl and a five year old boy, to writing computer code.

Agile

Agile Analysis

Analysis of user stories is a building block for a successful sprint and a skill that each Agile team needs to develop. My preference is for as much analysis to be completed before development of a user story begins.

Agile

Embracing Change

The Agile development process encourages us to respond to changes in requirements as a regular part of the process. How we react to unexpected change can define a team’s Agile maturity. Embrace change. This is what gives you and your organisation a competitive edge.

Posts, Pages and Categories

Most blogging platforms including WordPress and Ghost use the concept of a post versus a page to distinguish two types of content. It’s important to understand the difference before going too much further.
