Small businesses are always searching for ways to improve their efficiency, productivity and profitability.

Understanding the gap between work-as-imagined and work-as-done is important for business owners to truly understand how their business operates and acts as a platform to improve ways of working.

A fantastic tool that big organisations use which smaller enterprises can benefit from is hierarchical task analysis or HTA.

What is hierarchical task analysis?

HTA is a comprehensive method widely employed in human factors research to systematically dissect and analyse complex work or control tasks.

Originating from the pioneering work of John Annett, HTA enables the representation of goal-directed human behaviour by hierarchically organising main task goals into subgoals, which in turn comprise the necessary actions to achieve the overarching objective. This structured approach allows for a granular examination of task dependencies and operational intricacies.

Initially employed to identify training needs in specialised industries like the chemical and power sectors, HTA has evolved to encompass various fields, including team operations like client and project management, user experience and product design and process improvement.

With its versatility and methodical approach, HTA is often used for designing technical support systems and individual operator training programmes. By delineating task hierarchies and outlining performance criteria, HTA facilitates the enhancement of operational workflows and contributes to the evaluation of support systems in terms of workload management and cognitive resource allocation.

By focusing on the 'how' as well as the 'what', HTA offers a structured framework for improving efficiency and effectiveness in human-machine interactions, underpinning the foundation of modern business operations.

The fundamental tenets of HTA

To go about implementing HTA effectively, businesses should adhere to these key principles:

1. Task decomposition

Complex tasks are deconstructed into smaller, digestible sub-tasks, forming a hierarchical framework. This approach simplifies intricate processes, making them more manageable and easier to understand.

2. Hierarchical organisation

Tasks are structured hierarchically, with overarching goals positioned at the top and increasingly granular sub-tasks arranged beneath. This hierarchical arrangement offers a clear roadmap for task execution, guiding users through each step of the process.

3. Task dependencies

Dependencies between tasks are meticulously identified, encompassing sequential, parallel and conditional relationships. Understanding these dependencies is crucial for orchestrating seamless task execution and avoiding bottlenecks or errors.

4. User-centred perspective

Tasks are analysed through the lens of end users, ensuring that system design aligns with their needs and expectations. By prioritising user experience and usability, businesses can optimise task performance and enhance overall efficiency.

The advantages of HTA for small businesses

For small business operations, hierarchical task analysis is an unassuming yet powerful tool that can streamline processes and enhance efficiency.

Small businesses, often constrained by limited resources, can leverage HTA to gain deeper insights into task structures and user interactions, a method originally embedded in Human Factors Engineering but now widely recognised for its utility in user experience (UX) design and research.

1. Boosted efficiency

By structuring a high-level task into a detailed hierarchy of subtasks, HTA provides small businesses with a magnified view of operational intricacies, facilitating optimisation and innovation. With this granularity, inefficiencies that typically lurk in the folds of broader strategies are laid bare, enabling targeted improvements and informed decision-making.

2. Engaged employees

This detailed structuring is not merely academic but finds practical applications in product development, providing a blueprint for engineers and designers alike. When new employees are onboarded, the lucidity of an HTA chart can significantly shorten the learning curve, as it offers a clear, visual map of the tasks at hand. Such reduced ambiguity lends itself to increased job satisfaction among employees. HTA fosters a better understanding of roles and responsibilities, which can lead to improved morale and productivity.

3. Streamlining success

With its utility extending beyond internal efficiencies, HTA becomes an important tool for comparing different approaches to similar tasks, often revealing the most streamlined path to success. Serving as a compass for UX designers, for example, HTA guides team members through the labyrinth of user-system interactions at varying levels of abstraction. And in this age where customer experience can dictate the rise or fall of a business, HTA provides the foresight needed to craft experiences that resonate with users and keep them engaged.

4. Quality enhancement

HTA helps small businesses to fine-tune their offerings, applying a meticulous approach to quality control that evolves with customer feedback, production variables and shifting market demands. It is this agility – rooted in the structured analysis of HTA – that enables a small business to not just meet but exceed customer expectations, fostering satisfaction that turns first-time buyers into lifelong patrons.

Implementing HTA in business

The integration of HTA into business operations is a strategic endeavour. The journey begins with a clear-eyed assessment of the goals that the business seeks to achieve through HTA.

Once the objectives are set, the real pulse of HTA – engagement with the teams who keep the gears of these processes turning –begins. It is through these individuals, those who navigate these tasks day in and day out, that you can extract the nuanced insights that make for a comprehensive analysis. Their input is not merely beneficial, it is a cornerstone of the HTA process.

Involving them early on can not only ensure a more accurate analysis but also promote a sense of ownership and acceptance of subsequent changes, thereby easing the transition towards new operational frameworks.

Equipped with insights from your team, the next step is to articulate these processes visually. Flowcharts and diagrams serve as the canvas on which the complex web of tasks is mapped out, making it possible to pinpoint inefficiencies, redundancies or opportunities for automation.

This visual representation acts as a shared language for all stakeholders, clarifying roles, dependencies and workflows in a manner that is easily digestible.

By adopting HTA, small businesses can streamline their operations whilst enhancing product quality, employee satisfaction and decision-making capabilities. In embracing this approach, small enterprises set themselves on a path to sustainable success and innovation.
