British Airways security update stops ticket sales

I just logged into my BA account to book a ticket, but BA does not want my business because they have implemented new security without thinking about the impact on users.

After making my selection I'm shown the page below instead of a flight selection page. I could understand getting this if I'm not logged in, but I am so I have already authenticated my session. But there is no excuse for sending me to a blank screen, my firewall does not block Captcha, I know this for a fact.

When was this tested or has it gone up today without being tested, who knows?

---- A few minutes of testing later ...

I have now managed to get it working and BA have fallen for the classic developer problem, the new security page has been developed on FireFox with Internet Explorer an after thought. The Captcha loads in FireFox but does not in IE.

Now here is a description of one of the worst user experiences possible;

  • In FireFox I first log into my account, I'm in they know who I am.
  • Then I do my search selection.
  • I get the Captcha page fill it out, great I'm in my results
  • Now the clear thing is and everyone who books travel online know is that (sorry back now, I was in Heathrow and had to get my flight, ironic that I was in the BA lounge trying to buy a ticket but being stopped by poor usability) searching and finding are two different experiences.
  1. The British Airways flight search tool has always been bad as it does not cross link results e.g. Date, Location, Tier unless you search again, this is because the person who designed it does not think like a passenger. Potential passengers want to get somewhere, that is their first requirement, not to select class of travel. If you want a good standard look at EasyJet flight search, if you can forget all the other painful experiences and thinking the search is really very good.
  2. Now some bright spark at BA has looked at the log statistics and thought we are getting lots of drop outs and re-searching, this could be a denial of service attack, it's not, it is in fact the only way to find flights.
  • So my results only show me one class of flight, to see the other ones I have to search again, if I do I get Captcha again and again and again as I try and cross relate the various sets of results to get the best deal, that gets me where I need to get, when I need to get there.
  • Really, really painful experience, oh and I still have not booked a ticket because I was so angry at my treatment, I gave up.

What to do next?

  1. Sack someone, really, they made my evening hell!
  2. Hire a User Experience Architect (must be technical as they will lead the IT part too, so not a graphic designer) who will tell you how to redesign your search results and change how the back end IT works.

Do e-Commerce statistics prove customer affiliation?

Statistics for e-Commerce can be split between two contrasting and not necessarily companion aspects. There are statistics of success in terms of market development, profile or response through hit or link ratings, and secondly there are statistics of sales or revenue. Dependant upon the purpose of a company’s e-commerce deployment one or other but rarely both of these statistics will seek to prove the status of the investment and allow informed strategic decision making.

According to the United Kingdoms Office for National Statistics (ONS) in 2002 “e-commerce is likely to have a huge impact on the way we do business. It has the potential to lead to dramatic growth in trade, increase markets, improve efficiency, effectiveness and transform business processes”. This notion of increasing markets and improving efficiency and effectiveness through internet technology is underwritten in ‘Blown to Bits: How the New Economics of Information Transforms Strategy’. (Evens, 1997). Here the authors determine that three key factors create success in e-commerce businesses: reach, richness and affiliation.

  • Reach indicates numbers of users interacting in e-commerce.
  • Richness is the depth or quality of information user’s gain.
  • Affiliation is a measure of correlation or affinity with users.

The internet’s ease of accessibility for consumers means there is a levelling of reach between small and larger enterprises. This is due to small companies being able to gain the sort of competitive advantage associated with advertising in other media such as newspapers or television. Richness or detail of information is also easier to provide online with multiple data sources, animations, video and databases linked to internet and extranet applications. Only affiliation with the customer is unchanged and this creates a greater effectiveness and success through tailored services such as the Amazon personal front page (Wolverton, 2000) by making a new store for each user. It is in an attempt to measure affiliation or user buy in, that many commercially based internet statistics are created. This pressure to create statistics often to prove the effectiveness of the method by companies with a vested interest renders many internet statistics unreliable . To quantify affiliation and supposedly shed light on the nature of business transformation, increased markets and improved efficiency of e-commerce as a marketing channel numerous calculation methods are in use.

Credibility and Trustworthiness

There are two distinct terms associated with the effectual usage and profitability of e-commerce, credibility and trustworthiness. James Rosenfields (2001) determined that much of the available internet statistics are “lies or damned lies”. This is because they are “an amalgam of guesswork, wishful thinking, pie-in-the-sky optimism, end-of-the-world pessimism and trivial commonplaces” (Rosenfields, 2001) and therefore lack credibility. Much of the underlying basis of e-commerce statistics are not transparent and in many cases appears to be clouded by commercial purpose. James Rosenfields further suggests that the longevity of the medium, newspaper being old verses the internet being new has a direct correlation in its perceived trustworthiness. This notion of trustworthiness is essential in developing business to consumer (B2C) e-commerce in a way that many companies are used to working by letters of agreement, tacit contracts or unsecured credit whereas consumers are not. There is a general perception by consumers that more credit fraud is created by unsecured internet connections than them not keeping a watchful eye on their credit cards in shops and bars. In fact 5% of all internet sales using credit cards are fraudulent and carried out by consumers against merchants (Sandoval, 2001). In consequence credibility and trustworthiness are often outside the experience of many web retailers and sets an environment of fear in e-commerce.

Foundational Statistics

Given the commercial value of internet statistics governmental websites have been chosen as a prime source of information. While governmental statistics may be open to influences by national economic concerns, the first and most fundamental statistic of total population holds no specific national benefit so may be considered viable. The U.S Census Bureau issues world population data which has been factored to be 6,446,131,400 (U.S Census Bureau, 2004) at a mid point in the year of 2005. Conversely this data is used with an algorithm by David Levin from the University of North Carolina in his population clock which goes up three to four people per second. At 12.30pm 7th April 2005 the population stood at 6,511,632,444 (Levin, 0000). While this format of data presentation is quite compelling it is without consensus and as such flawed. If the population of the world is not an agreed figure it is therefore difficult, if not impossible to determine a percentage usage of the internet as a derivative of world population. Further more to calculate return on investment (ROI) in association with internet usage, sales figures and market penetration by population methods would also be impossibly flawed.

Statistics of Success

There are many methods of statistical calculation in use on the internet e.g. click through rates (CTR) which are derived from using coded links which log activity and flow direction, website visitors which is an extrapolation of site hits, data requests and site session logs. However the underlying data is captured in only two arenas. Data is derived from either locally assessed user activity or remotely assessed communication packets or logging. These two data sources then form the basis of calculations in association with national and worldwide population statistics.

Activity Statistics

Activity statistics are derived through the use of pre-defined or targeted user groups surveys or reviews, cookies, banners, html email, adware and spyware.

Predefined groups are used by Nielson NetRatings to produce commercial guidelines for internet design. They include recommendation of functionality, content design and creation and accessibility. Commonly, internet experts are used to assess websites, they perform heuristic evaluations based upon defined criteria. This method is highly favoured in commercial arenas as it provides absolutes. An unfortunate aspect of this sort of evaluation is a level of condescension is required to dumb down the findings to allow for non technical usage of the internet. While this kind of study may produce insights into professional aspirations for internet usage it says very little about mass consumption. The motivation for this kind of study is consultancy or publication fees. The use of this sort of data to describe national or global interactions is highly suspect.

Targeted user group are used to perform ethnographic reviews commonly in users office or home that study interactions based upon goals, walkthroughs or scenarios. This type of study is highly effectual in producing notional interaction behaviour. Until recently the use ethnographic reviews has been associated with a response to an existing website rather than the underlying philosophy or ethos.

e-Commerce concepts and research

The following is a paper I wrote in 2005.

Converting browsers to buyers: exploring what drives consumer choice in internet e-commerce

Why do internet users behave as they do, are their activities solely determined by website design? Or do they create their own pathways as a response to designated systems. For many, internet design is about the imposition of schemas, predetermined flows and consumer motifs, allowing the shepherding of an understood and mapped user towards buying products and services. However if this were true then every browser would also be a buyer. The underlying concepts of current website design rely on a number of pretexts which, when reviewed in relation to human activity and interaction, become questionable in their veracity.

1.       INTRODUCTION

There is recognition [16] that there is limited information in the understanding of the reciprocity of attitudes and behaviour constituting the relationship between internet shoppers and e-commerce websites. This is in contrast to commercially driven usability and web metrics companies who assert their findings based upon activity patterns often using statistically small samples [15]. Developing an understanding of the relationship between users and websites is key to determining patterns of interaction. Patterns of interaction are currently under investigation in two distinct ways, by using reflective and diagnostic methodologies. Reflection upon measurable activity, clicks, information foraging [5] and sales provide compelling insights for business metrics, can be limited by their subjective constituents. In turn diagnosis based on reviewers or heuristic interpretations with little user involvement [15] produce contentious results. This study will attempt to combine both forms of investigation with a large participant group study producing empirical data to be reviewed using both quantitative and qualitative approaches.

1.1         Research aims

The aims and objectives of the research can be summarised as follows:

  • Why do internet users behave as they do, are their activities solely determined by website design? Or do they create their own pathways as a response to designated systems.
  • List common behaviours and attributes to discern if there is a pattern that can be mapped and predicted.

These present some added details in comparison to the original project aims and objectives, described in the project proposal (appendix 6). Differences and the reasons for them are discussed in the final conclusions (chapter 6).

2.       E-COMMERCE THEORETICAL UNDERPINNING

The main area of this research is to gain an understanding of how people use technology as an extension of their world [10], specifically in the mode of consumer e-commerce. This world view is augmented by a representation of social constructs by an evolutionary process of active agents of transformation [4] in technology and specifically the creation of an electronic media habitus. This constituency maintains its own cultural capital and produces a parallel distinctive counterpoint to popular and consumer cultures. The nature of human computer interactivity, it's cultural, educational and gender attributes has a key influence on the unification of money, knowledge and technological aspiration. These factors are also represented in technological deprivation and the personalised safety of internalised ignorance.

To relate instances of electronic media habitus a combination of activity biography [1], [12] and negotiated conventions [7] enable the development of an activity definition index. The cultural disposition of technology, interactions and resultant pathways remain difficult to interpret without recourse to such a framework.

3.       REFLECTIVE METHODOLOGY

Existing methodologies produce results that use complex mathematics to create algorithms [6], create subjective rules of design [15] or usability inspection tools [3]. Which are normally only used with existing websites, only reflecting upon current interactions.

2.1 Information Scent

The cognitive walkthrough of the web has evolved based upon the notion that users decide on their course of action based upon cues, which derive behavioural patterns of interaction then form guide routes of information scent [3]. Information scent has also been developed using aspects of information foraging both structured and unstructured [6]. The Bloodhound project seeks to establish a clear method showing consistent, measurable elements that provide benefit in the design of websites. However there is contention in the effectiveness of this methodology [14] by commercially driven consultants.

2.2 Internet Statistics

There remains a problem with accessing "actionable statistics" [8] for businesses, and while their credibility and measurability remains opaque there will be a question regarding their veracity [18].

4.       DIAGNOSTIC METHODOLOGY

The general interpretation of an open and untamed [2] source of information like the World Wide Web (WWW) requires a systematic review of actions. Actions and user activity [11] in relation to an observable world require a common representation to determine navigation and related target acquisition. Ethnographic studies related by an in-series testing system can reduce the anomalous results associated with subjective reflective data. Ultimately a lexical definition of activity is needed; in the interim the term narrative enables an interpolative review of data which will provide a clearer definition of activity.

3.1 Narrative

The understanding of human interaction can be viewed as participation in the creation of personal historical elements, which allow dispersion in potential trajectories [10] evolving of a self imposed narrative. This narrative can be observed in linguistic and engendered functions which require definition and contextualisation. However to effectively map these functions a lexicon approach [9] as associated with endangered languages, would allow the use of rational linguistic dimensions including orthography, morphology, syntax and semantics. The creation of a lexical basis [17] makes individual actions communicable aspects of communities of actions with related compound, processed and adaptive meanings.

Several hypothetical goals, adaptations and conventions can be derived from this research which will further refine and delineate additional aspects of narrative behavior to produce foundational lexical and activity indices.

3.1.1 Goals

Goals can be a descriptor of predetermined final destinations which can subsequently be reduced to a form of knowledge morpheme. These inter-related sub-rationale units while distinct and finite offer an activity based response to catalytic impositions by addition and adaptation.

3.1.2 Adaptations

Adaptation allows the extension of narratives [13] creating alternative perspectives on the same object or situation. Further modifications can be made in a process of engagement, by determining the user's perceptions or discernment of active adversity which produces redirection.

3.1.3 Conventions

Conventions allow the use of avatars [7] to create nodes within lexical frameworks, providing index points in a narrative activity. Agreement of conventions in social, emotional and commercial arenas for completion, enable a measurable resolution to tasks.

5.       PROPOSED RESEARCH METHODOLOGY

Data for this paper is being gathered through a three tiered research process. The target group for this research is consumers who purchase online, non-experienced WWW users based in the United Kingdom.

An initial pilot survey link has been introduced onto a number of United Kingdom based online shopping directories. Control questions have been used to define the target group and acquire basic demographic information. The survey consists of open ended questions with text areas to allow user to express their opinions on their online purchase experiences.

The main survey will be derived from the pilot by asking detailed questions related to the pilot results. This survey will use menu and dropdown tools with text areas to create both quantitative and qualitative primary data.

The final counterpoint survey will involve twelve participants (six consumers and six heuristic users) working on a series of scenario based activities derived from the main survey results. This ethnographic study will allow interactive testing and appraisal of user preferences, requirements and actual activity.

6.       CONCLUSION

While this paper seeks to review and define the boundaries of an ongoing associated data gathering exercise it has also produced a number of testable hypotheses to be reviewed after data acquisition.

The linking of action cues with ethnographics has the potential to define activity components, constituents, usage and compound derivatives which will allow measurable patterns of formation and defendable narrative component interpretation.

The use of lexical representations will provide a framework for the indexing of interconnected activity components which currently operate under diverse notations.

The ability to interpret interaction will form the basis of other studies to better understand and design e-commerce sites based on human interpretive activity.

User stories is another name for a cognitive walkthrough

I have been involved in Agile for a very long time, mainly because it uses methods from the human computer interaction scientific process (CHI/HCI).

I’m surprise no one else has blogged about the use of CHI/HCI processes in Agile before, but though I should say something as I keep getting told that it’s interesting how many CHI/HCI people have embraced Agile. In fact it’s the other way around we have simply re-appropriated our own techniques that have new Agile names.

The main one is User Stories; they are in fact a reuse of the Cognitive Walkthrough, but I’ll let you draw your own conclusion.

Cognitive Walkthrough is a method utilised to determine the potential usability failures within an interactive system.

The method starts with a task analysis that specifies the sequence of steps or actions required by a user to accomplish a specified task. The system response to each action is noted. The designers and developers of the software then walk through the steps as a group this enables an agreed view. They ask themselves a set of defined questions at each step to determine all the potential outcomes. Afterwards a report of potential issues is compiled and the project team has a clear focus on the various user pathways including happy paths, risky paths, error paths and failure paths.

User Stories are a quick method to determine the who, the what and the why of a business requirement and are produced in a narrative format as if a user was walking through their use of an interactive system.

User stores are written at two levels Epic Stories that define groups of functionality (registration) and User Stories that define a single piece of functionality (sign in).

User stories are written by the product owner (an Agile tile for stakeholder or product manager) a user experience architect or a business project manager (not a scrum master) or the development team when they break down stories that are too large (these are then confirmed by the product owner).

The method starts with defining the Epic stories, then breaking these down into smaller stories that relate to an encapsulated (self standing) component. In design and development these stories can be parcelled to the various specialisations including user research (end user validation, How It Works), visual design, user experience design, back-end development (feature and service delivery), security and front end development. These stories will have their interlinks (to other components) stubbed out until those stories are built and can be integrated.

Agile + CHI/HCI = User Centred Requirements, User Centred Design and User Centred Development.

They are not exactly the same but the essential method is, think like a user, describe what you can do and build the system that enables a user to complete a task or gain a feature and that is the same.

Blended program management, Prince and Agile methods Part 1

I have been involved in project and program management since 1989 across various sectors and more recently have been focused in banking and finance. I have experience in Prince and Agile methodologies and will expand on the blending of these two methods through the use of user stories (a user experience method) and the positive relationship between waterfall and iteration components in the following parts of this post.

Simply put (before getting into the detail) Prince and Agile = Delivery and in Banking and Finance they can give startling results.

This will not be a shock to many people but I'm not going to be describing the what, but the how. I have managed some highly complex projects that would have failed if they had been run in Prince or Agile alone. The clear advantage of blended processes is that the project become team centric and affords an environment where success in common and that value is attributed to the correct people.
