Accountability and Responsibility in Software Engineering

In software development, responsibility and accountability are closely related but have important distinctions, especially when it comes to leadership roles like a team lead. Responsibility refers to the obligation to carry out specific tasks or duties. Multiple team members can share responsibility for different parts of a project. For example, developers are responsible for writing and testing code, while QA engineers are responsible for ensuring that the code meets quality standards before release.

Accountability, on the other hand, means being answerable for the outcome of a task or project. While responsibilities can be distributed among several people, accountability typically rests with a single individual. In many software teams, the team lead is accountable for the success or failure of a given project or feature. They may not perform every task themselves, but they are the person stakeholders look to when results are delivered.

Consider a scenario where a new feature is being built for a mobile app. The backend developer is responsible for creating APIs, the frontend developer for integrating those APIs into the user interface, and the QA engineer for testing the feature thoroughly. While each team member is responsible for their own contribution, the team lead is accountable for ensuring the entire feature is delivered on time, meets quality expectations, and integrates properly with the rest of the application.

If a bug makes it into production because of a missed test case, the responsibility may lie with the developer or QA who missed it. However, the accountability lies with the team lead, because it is their job to ensure that the development process includes adequate checks and balances. This distinction helps ensure clarity in roles and ultimately improves team coordination and product quality.

Write Your Own Load Balancer: A worked Example

I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

Remember to Delegate: The Triangle of Trust

So you think you can lead a team? I’ve been talking and writing a lot about leading a software engineering team in 2025. I started thinking about it more deeply the year before when I decided to give a colleague, who was moving into team leading, some advice: 'Doing the work' isn't the only way to add value Remember to delegate Pick your battles Talk to your team every day Out of this came a talk, “So you think you can lead a team?” which I gave at work, at meetups and at conferences in various different formats during the first quarter of 2025. Here I am looking at Remember to Delegate and an idea which came out of discussion around the talk, The Triangle of Trust, in more detail. Delegate Delegation is a crucial skill for any team lead, yet it is often one of the most challenging aspects of leadership to master. Many leaders, particularly those who have risen through the ranks as individual contributors, struggle to let go of tasks, fearing a loss of control or a dip in ...

Catalina-Ant for Tomcat 7

I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th...
