Personal Story: My father was trained as a typographer in the printing industry. As a professional, he specialised in the design and arrangement of typefaces or fonts for printed materials, using physical lead type arranged upside down and mirrored to make newspapers, letterheads, brochures, etc. In the 1980s, my father bought our first PC (an Amstrad) with a publishing program that allowed files to be printed directly to the new printing presses, eliminating the need for laying out physical lead type. I learned many things from my father that are reflected in today's graphic designers, such as attention to typography, design principles, and a focus on visual communication. However, one key lesson was that the tool you use, whether lead type or a computer program, does not result in the perfect design; it's the people with knowledge of typography or graphic design who achieve perfection.

Interesting Fact: Graphic design has roots in ancient art forms, but the modern field emerged with the invention of the printing press in the 15th century. 

"H" for Hacker (Ethical). Software Development Roles: A to Z

An ethical hacker's role is to proactively identify and address vulnerabilities in computer systems, networks, and applications. By simulating cyberattacks, they uncover security weaknesses before malicious hackers can exploit them. But here's an interesting thought: when you're hacked, would you even know? Does that last email you read seem a bit off? Or perhaps that video you’re watching feels inconsistent with your usual content?

Personal Story: In the past, I’ve engaged in ethical hacking, but with the rapid advancement of technology—especially with AI—it's become a field where I now prefer to leave the work to specialists. However, my experience as a Privacy Officer has shown me the importance of ethical hacking within the context of New Zealand’s Privacy Act 2020. If a data breach occurs, there are specific steps you must follow according to this Act. Have you ever conducted a Privacy Impact Assessment (PIA) for your project? This is typically done before the project begins, especially if it involves handling personal information. In many cases, it’s a legal requirement. Interesting Fact: Did you know? The term "hacker" originally had a positive meaning, describing individuals with advanced technical skills who enjoyed exploring and experimenting with systems.

"I" for Infrastructure Engineer. Software Development Roles: A to Z

Infrastructure Engineers play a critical role in maintaining and managing an organisation's physical infrastructure, including servers, networks, storage, and peripherals. They are responsible for designing, implementing, and monitoring infrastructure solutions that support various applications and services.

Personal Story: From my personal experience, beware of the inbuilt recommendations within Azure or Amazon Web Services; they are very quick to advise but very slow to explain the associated pricing. After enabling a security feature in Azure to enhance security, we later discovered that our subscription costs had increased by hundreds of dollars due to this simple change. We turned it off, and Microsoft kindly adjusted the charge. The exciting changes I've seen since the inception of cloud computing include the introduction of serverless functions around 2015 and the recent advancements in Cloud AI in the 2020s.

Interesting Fact: The concept of infrastructure engineering has evolved alongside advancements in computing technology, from mainframes and client-server architectures to cloud-based infrastructures.

Additionally, I’ve employed JavaScript in test automation with Playwright and Jest. However, a former colleague of mine believed JavaScript lacked structure compared to C#, citing issues like global scope, callback hell, and type safety concerns. I also recall an amusing encounter with a salesperson who insisted that JavaScript was just a script written for Java. Despite my efforts to explain the difference, I suspect he was simply trying to wind me up. Fact: Did you know? Both Java and JavaScript are among the most widely used programming languages, powering a diverse range of applications and platforms on the web and beyond.

"K" for Knowledge Manager

A Knowledge Manager ensures employees have access to accurate and relevant information and resources across the organisation. They facilitate knowledge sharing through various channels, including training sessions, online platforms, and written guides.

Personal Story: In one organisation I worked with, the Knowledge Manager's goal was to make information and training accessible to everyone and connect people to workshop their knowledge, leading to better project outcomes and improved work processes. A key lesson I learned was that having a WIKI or SharePoint is not the same as having a knowledge base—these are merely document repositories. True knowledge management involves using information to enable better outcomes for the entire organisation. It's a unique and often under-appreciated role. Did you know? Knowledge management draws from various disciplines, including information science, organisational psychology, and computer science, to optimise the creation, storage, and dissemination of knowledge.

"L" for Lead Developer. Software Development Roles: A to Z

 A Lead Developer manages and mentors a team of developers, ensuring the successful completion of software development projects within timelines and budget constraints.

Personal Story: Having served as a Chief Operating Officer (COO), I've learned that operations management extends far beyond software development. It's essential for ensuring the foundational aspects of a business, like payroll, employee contracts, and client agreements, are meticulously handled. In software development, decisions often fall into three categories: Business as usual tasks that must be completed, opportunities like client workshops exploring AI solutions for medical issues, and distractions such as pursuing new, less relevant ventures like developing AI-powered rocket fuel. These classifications can shift based on new information, evolving assumptions, or changing contexts.

Interesting Fact: Operations management principles trace their origins to industrial engineering, gaining prominence in the early 20th century alongside mass production and assembly line techniques.

 

"P" for Product Owner. Software Development Roles: A to Z

The Product Owner plays a pivotal role in agile development, defining and prioritising the product backlog to maximise team value delivery. They act as a crucial bridge between stakeholders and the development team, translating business needs into actionable user stories and acceptance criteria.

Personal Story: In my role as a Product Owner, I delegate defect and business-as-usual work items to the team, ensuring these tasks are managed within an agreed percentage of the total workload, typically around 30%. I also enjoy introducing experimental work items into the backlog. Each experiment has a clear hypothesis and defined success criteria, enabling data-driven decision-making.

Interesting Fact: The "owner" in Product Owner signifies the leadership, decision-making authority, and responsibility held over the product’s direction and success, rather than implying legal ownership.

"Q" for Quality Manager. Software Development Roles: A to Z

A Quality Manager oversees the quality assurance and control processes within an organisation. They ensure that products or services meet established standards of quality, reliability, and performance. Quality Managers develop and implement quality management systems, conduct audits, and analyse data to identify areas for improvement. Personal Story: As a Test Manager at a healthcare medical device company in the United Kingdom, I worked closely with a Quality Manager. Our collaboration was crucial in ensuring we met the highest standards of quality and compliance for ISO 9001 (Quality Management System) and ISO 13485 (Medical Devices – Quality Management Systems). The Quality Manager provided strategic oversight, established frameworks for quality assurance, and ensured that QA processes aligned with organisational goals and industry standards. As a Test Manager, I led the testers, whose contributions to quality assurance included rigorous testing activities. Distinction Between Testers and QA: It's important to understand the difference between Testers and QA, especially as many New Zealand consultancies incorrectly use the term "QA" when they actually mean testers or testing activities: Testers: Focus primarily on executing tests to gather information about a system, identify defects, and ensure that software meets functional and non-functional requirements. QA: Encompasses a broader role, including establishing quality standards, defining QA processes, conducting audits, ensuring compliance with standards and regulations, and driving continuous improvement across the entire organisation. Interesting Quality Management Fact: The concept of quality management dates back to the early 20th century, with pioneers like Shewhart and Deming laying the groundwork for modern quality assurance practices.

"R" for Release Manager. Software Development Roles: A to Z

A Release Manager is responsible for overseeing the planning, scheduling, and coordination of software releases. They ensure that new features, updates, and fixes are delivered smoothly and efficiently from development to production. Release Managers work closely with development and operations teams toå manage the release lifecycle, including scheduling, testing, deployment, and post-release support. Personal Story: As a Delivery Manager, one of my key responsibilities was Release Management. This role involves coordinating, communicating, planning, scheduling, and controlling the movement of releases to test and live environments across various platforms. Many people think a software release simply means distributing a new or updated product to end-users. However, technically, a release refers to any change to a software product or system outside its normal operating premises. Interesting Release Manager Fact: The role of a Release Manager has become increasingly important with the adoption of Agile and DevOps practices, emphasising rapid iteration and continuous delivery of software updates.

"S" for Scrum Master. Software Development Roles: A to Z

A Scrum Master is a servant leader and facilitator for an agile development team. They ensure the Scrum framework is followed, enabling the team to maximise its efficiency and effectiveness. Scrum Masters coach the team on Agile principles and practices, helping them to self-organise and make decisions collaboratively.

Personal Story: I have been a Scrum Master for several teams. One thing I love is educating people new to the Scrum framework. One method I use involves the office kitchen. Imagine the product backlog as four different drinks: a cup of tea, a latte, a glass of water, and a long black. Sounds simple, right? However, without acceptance criteria, the team quickly learns that the drinks made aren't what the end user wanted! The first tea made: "Why is there a tea bag in my tea?" The first latte: "I wanted oat milk!" This hands-on experience helps illustrate the importance of clear acceptance criteria and continuous learning.

Interesting Fact: The Scrum framework was formalised in the early 1990s, drawing inspiration from empirical process control theory and lean manufacturing principles. It was visually likened to a rugby scrum, with the team moving as one down the field.

"T" for Tester. Software Development Roles: A to Z

A Tester plays a critical role in verifying the functional and non-functional aspects of software applications. They identify defects and usability issues through thorough testing processes and collaborate closely with developers, product managers, and other stakeholders to understand requirements and create effective tests.

Personal Story: Having run a test consultancy company in the past, I’ve gained significant insights into being a tester and have found some very interesting defects over the years. I like the term Tester—it's simple and to the point. However, many testers have more specific titles, often reflecting the domain they work in, such as: Software Tester, Mobile Tester, Web Tester, Security Tester, Usability Tester, API Tester, UAT Tester (User Acceptance Testing), Embedded System Tester, Game Tester, Network Tester, Performance Tester.

Then there are testers with "Engineer" in their title, such as Test Engineer, Test Automation Engineer, and Performance Engineer. This likely stems from the idea that if you can have a Software Engineer, you should also have a Test Engineer, especially since they often write code to enable their testing.

Titles like Test Analyst imply a focus on analysing requirements and designing tests. In consultancy, you find titles like Test Consultant, Senior Test Consultant, and Principal Test Consultant.

However, titles with "QA" in them can be misleading. Quality Assurance (QA) is a broader discipline, often managed by a Quality Manager, which differs from the tester's role.

Interesting Fact: The origins of systematic software testing can be traced back to 1947, with pioneers like Grace Hopper at Harvard. The earliest documented "bug" was caused by a moth trapped in a machine. Fun fact: a moth is actually an insect and not a bug.

"U" for UX and UI Designer. Software Development Roles: A to Z

As a UX and UI Designer, you are responsible for creating and implementing user-centred experiences (UX) and visual user interfaces (UI) that align with the organisation's branding guidelines and user requirements. This role involves understanding user needs, conducting usability testing, and iterating on designs to ensure software products are user-friendly and meet aesthetic goals.

Personal Story: A key lesson in user experience design: always develop and test on the devices your customers will use. In the early 2000s, I was involved in a project where a new system was designed for expensive Quad HD screens (2560x1440 pixels). However, our development team only had Full HD screens (1920x1080 pixels) for development and testing. A Quad HD screen has approximately 77% more pixels than a Full HD screen. When we first trialled the software with a customer on a Quad HD screen, we quickly realised that the “Save” button at the bottom right was far from the “Confirm” button at the top left. The customer found this inconvenient, though they noted that the “Save” button did work. The issue was simply that the mouse had to travel much further to reach the “Save” button. We resolved this by moving the button and ensuring our development team had access to Quad HD screens for future projects. Fact: Interesting UX Fact: The field of UX design emerged in the late 20th century with the rise of human-computer interaction research and the recognition of the importance of user-centred design in creating successful software products.

"V" for Vendor Manager. Software Development Roles: A to Z

 A Vendor Manager is responsible for ensuring the smooth and efficient delivery of software components from vendors. Their role involves working closely with vendors to negotiate contracts, monitor inventory levels, and coordinate deliveries to ensure that projects are delivered on time and within budget.

Interesting Vendor Fact: The term "vendor" originates from Latin. It comes from the word "vendere," which means "to sell," highlighting its historical connection to commerce and trade.

"W" for Writer (Technical Writer). Software Development Roles: A to Z

Technical Writers play a crucial role in translating complex technical information into clear and concise documentation. They are skilled communicators who collaborate closely with engineers, developers, and subject matter experts to create user manuals, technical guides, and documentation for software applications, products, or processes.

Personal Story: I marvel at those who can make language clear, concise, and consistent. This might be why I'm married to a Technical Writer. Her regular instructions used to be, "Dear, I would love a cuppa tea, no milk, no sugar, and a little cold water." Over time, this has become more concise: "Dear, love a tea." Now, sometimes, it’s just a look. Amazing skill.

Interesting Fact: Technical Writing has a rich history dating back to ancient civilisations, with examples such as technical manuals for ancient Egyptian construction projects and medieval manuscripts on alchemy and metallurgy.

 

"X" for Xpert (Subject Matter Expert). Software Development Roles: A to Z

 Subject Matter Experts (SMEs) are invaluable assets within an organisation, recognised for their specialised knowledge and deep expertise in specific fields. They provide essential guidance, support, and solutions to complex challenges, collaborating closely with teams, stakeholders, and leadership to ensure informed decision-making and effective problem-solving.

Personal Story: Experts can provide insights into situations that might take days or months for others to understand, or where critical concepts might be overlooked. I consider myself an expert in various software development areas, such as team leading, testing, agile frameworks, and DevOps. One of the best experiences is having a coffee with an expert and exploring a subject. Recently, I explored a new business idea requiring an IoT solution to capture images based on movement. Initially, my limited knowledge led me to consider a Raspberry Pi with a single camera continuously monitoring images. After two coffees with an expert, we developed a solution with motion detection to start image capture when needed, multiple cameras feeding one microprocessor, and some other innovative design ideas.

Interesting Fact: The term "Subject Matter Expert" gained significant usage and recognition in the 1960s and 1970s, particularly in industries like aerospace, defence, and technology companies.

"Y" for YAML Expert. Software Development Roles: A to Z

 A YAML Expert is a specialist proficient in YAML (Yet Another Markup Language), a human-readable data serialisation standard. Their role involves mastering YAML syntax, structure, and best practices to ensure efficient and error-free configuration management.

Personal Story: One thing I've learned over the years is the necessity of becoming an expert in "Yet Another" technology, scripting language, or markup language for different projects. For example, I had to learn YAML for configuration on a recent project. The challenge with YAML is that incorrect whitespace or indentations can break your configuration, leading to parsing errors and incorrect data structures. Using IDEs that support YAML syntax highlighting and validation helps significantly. Additionally, be very careful when cutting and pasting into a YAML file, as this can introduce unwanted whitespace or indents.

Interesting Fact: YAML was designed to be a simpler alternative to XML and JSON, focusing on readability and flexibility.

"Z" for Zero-Day Analyst. Software Development Roles: A to Z

As a Zero-Day Analyst, they specialise in identifying and mitigating zero-day vulnerabilities in software and systems. These vulnerabilities, unknown to vendors or developers, are critical targets for exploitation by malicious actors.

Personal Story: In my experience, most zero-day issues fall into one of two categories: The operating system has a vulnerability that requires an upgrade or patch to be applied ASAP. Did you know? Zero-day vulnerabilities are particularly dangerous because there are no patches or fixes available to protect against potential attacks, making them a significant threat.
