Expert reviewing a heuristic evaluation

6 Aug

I recently changed jobs and now work as a User Experience Consultant at Interaction Design Studio. Since starting I’ve been doing a lot of work conducting heuristic evaluations (HE).

Screen shot: Expert Review

Just to recap, a HE is an inspection method or review conducted by a usability expert, of a website which complies to widely accepted (and even adopted) design principles. These design principles (called heuristics) are what is considered standard practice or rather best practice. For example, when submitting form data the system should inform the visitor that ‘something’ is happening – processing, validating, checking, submitting – something that keeps the visitor informed. An ‘official’ widely used set of heuristics are Jakob Nielsen‘s ‘Ten Usability Heuristics‘.

A practitioner involved in the field of user experience conducting HEs is an essential skill and dare say one that should be mastered. Having the ability to pick apart a website and analyse its strengths and weaknesses has many benefits, notwithstanding cost-benefits and speed to conduct. Often the findings provide insights which allow website owners to fix the quick and easy issues, the low hanging fruit fixes. In most instances conducting a HE serves to highlight potential flaws and usability failings, but also suggest or recommend ways to fix or correct the issues.

I’ve been reviewing and reading HEs conducted by other practitioners. I find it kind of interesting to read their assessments. Often they spot issues which I may have missed, or articulate the problems differently. Reviewing HEs is also a good way off checking work too, making sure there are no errors, and of course it acts as a second pair of eyes strengthening the assessment process.

But, are we writing these reviews with the end-user in mind? Are we using technical terms with explanations? Quite often the reviews I write are written for business managers, website owners and marketers, and not user experience or usability professionals. So should we place more emphasis (on our writing) on our clients? Perhaps we should be writing both a technical and a normalised version? Or should we be documenting our findings providing explanations for technical terms which seem impossible to omit?

My view is that prior to writing a HE be clear about who its recipient is. All HEs or expert reviews should be written in normalised language and where unavoidable provide explanations for technical terms.

Mobile device switching, for improved productivity

Use Flow: User to submit press release from mobile device

Many of us working in the corporate world operate two mobile devices. In many instances the reason is primarily because the company has a corporate deal which involves an email exchange server and an associated Blackberry device policy. At the same time people have an additional smart phone for private use, like an iPhone. I know I do.

It’s widely accepted that certain functions work on some mobile phones but not on others and that operating those functions, like text documents, on different devices culminates in a better user experience. For example, trying to create and edit a document using an iPhone is seemingly easier than say the Blackberry (that does not include the manual operators, it’s the applications functioning).

During a recent usability test (testing a news wire iPhone app) I discovered that the participant did exactly as I do. When I asked how they would edit and send a document (press release) from their device they said they’d email the document from their work mobile device (the Blackberry) to their private mobile device (the iPhone) first, then edit the document on their iPhone before sending.

What contextualised findings have I learnt from the empirical usability test? Well, other than the specific functional insights originally set out, a) the only way to access work files is through the work device and therefore only good for emailing out* and b) workers are very good at finding alternative ways, albeit unconventional or perhaps inefficient, to complete tasks.

Agile UX

Matt Roadnight discussing Agile methodology (user story map slide)

I attended Agile UX SIG #2 last night at the ThoughtWorks where agile geeks met to discuss the much hyped Agile methodology. While I’m curious about all the fuss I’m also professionally interested to learn how Agile might improve workflow. Further, next year (User Interaction Design MSc) I’m enrolled in a ‘Agile Methodology’ module at university (see below). My hunch is Agile methodology will gather further momentum and become more widely adopted in the future so I need to pay attention to it.

Agile Development description:
This module provides a systematic understanding of the fundamental principles and techniques associated with agile project management, by linking the DSDM Atern framework with the object oriented paradigm through tools like SCRUM. Kingston University, CISM

Anyway, at last nights meeting Matt Roadnight, an Agile Scrum coach, explained how he coaches Agile Sprint methodology with business teams (his clients). Essentially there are three overlapping groups: Project Owner, Team Members and a ScrumMaster. Every project has what’s called a ‘Backlog’ – a set of items that must be designed/developed to progress the project. The project undergoes continuous flurries of meetings, or Sprints, where these backlog items (or groups of related and timely) items are discussed. Future items requiring attention are discussed in sprint planning meetings too.

Role definitions and responsibilities

Matt went on to define roles and stressed the importance of collaboration and communicating amongst each other he defined responsibilities. The Project Owner – typically a senior stakeholder – is responsible for the Vision which includes strategy, business case, user experience research, as well as ROI. The Analyst is responsible for the Features and finally the User Experience Designer is responsible for the Experience. While the Analyst may be a stakeholder too, the UED is customer facing. I might add at this point that there was a little push back from the attendees arguing that user experience and features should not be seen as separate activities… they should validate against each other.

Themes

Matt spoke about trying to group backlog items into related groups or Themes which focused on an particular aspect of the design. They are made up of units of User stories. A typical ‘story’ might look like this:

“As the <USER ROLE> I want to <PERFORM FUNCTION> so the <BUSINESS REASON>”

The next Agile UX meeting (in ~6 weeks time) will include a practical hands on 2-hr session walking through a typical lifecycle of an Agile project.

Who first conundrum surrounding product innovation and user needs

3 Jan

Recently, Don Norman, from The Nielsen Norman Group, posted (Technology First, Needs Last) what seems to be a provocative assertion that in product design, technology comes first, then it’s user needs. Put another way, of all the notable innovation to emerge the driver was technology (and not what UX design folk universally believe –  user observation and ethnography). Norman cites examples of how new products evolve when technologist take existing products and serendipitously produce innovative products. The examples include: “The Airplane, The Automobile, The Telephone, The Radio, The Television, The Computer, The Personal Computer, The Internet, SMS Text Messaging, and The Cellphone”

While still relatively new to the field of interaction design and all its associated family of off-shoots, I’ve found myself at a cross road of understanding. I’m looking for some clear thinking of what truly exists (of possible). The most frusting thing about the aforementioned assertions is it’s personally frustrating that I have no absolute stance. Let me continue and take a stab at it at this posts conclusion.

I’m currently reading Alan Coopers’, The Inmates Are Running The Asylum, in which Cooper begins by arguing that in a world of products operated by computer chips, products are being designed that do exactly what their programmers instruct them to do with very little user empathy. From his writings I deduce Cooper implies that we need to do more ethnography so that products offer better support and function to its users. Where technology leads it seems difficult to achieve this.

In James Kalbach’s post, Don Norman on Ethnography and Innovation, he counters Norman’s Edison example deducing:

“It would also appear that Edison did a type of ethnographic observation in inventing the light bulb”

My view of product design and innovation is that before a new product is realised many hours of work goes into understanding what users need or what would help better fulfill a users tasks. Time is spent observing – through ethnography and other methods – users and how they interact with their surroundings. Also, a great deal of time is spent truly understanding exactly what the problems are. Answering the ‘why do we need it?’ questions. After reading Norman’s piece I can see that there are alternative instances where innovation stems from evolution alone (using technology). As the world moves through the technology age, more and more instances of ‘technology-first’ will become evident.

My views are divided. I fully accept that new products (and services) are created by technologists first, especially nowaday’s for example in web applications, thus supporting Norman’s assertion. But, I also accept that there is a huge and essential role in understanding user needs that leads to innovative products development (and services).
