Usability, Usability Requirements and User Experience Goals

Usability is concerned with optimizing the interactions people have with interactive products’ and is achieved by defining usability and user experience goals. These goals aim to promote products which are effective, easy to learn and enjoyable to use. (Preece et al. 2002:14) Usability requirements capture usability goals and related measurements of these goals. (ibid. 2002:207) One approach is usability engineering’ which is a process whereby the usability of a product is specified quantitatively, and in advance’. (Tyldesley 1990:284) This means documenting planned levels of usability. For example with regard to the usability goal of efficiency’ outlined below, one benchmark is the time taken to locate a specific entry in an alphabetical index of a product. This is a measurable usability goal. Other usability goals are more difficult to measure and user experience goals, which are discussed below, are subjective and so cannot be measured in this way. (Preece et al. 2002:182) In this case qualitative or subjective, attitudinal measures of usability’ are used. (Tyldesley 1990:288) For example, interviews or surveys through questionnaires can be implemented. Once usability requirements have been defined, the product is developed iteratively until it is demonstrated that it achieves the projected levels of usability. (Preece et al. 2002:285) It is important that the product is easy to use, as the target users may have limited computer abilities. This can be achieved by defining usability requirements through consideration of the usability goals below. These requirements can also be considered in conjunction with design and usability principles such as visibility, consistency, constraints and affordance. (ibid. 2002:21-25) Furthermore, reference to design principle standards such as the International Organization for Standardization’s ISO 14915 Software ergonomics for multimedia user interfaces’ provides a framework to assist the designer in standardisation.
Effectiveness can be described as the level of performance of completion of tasks, (Shackel 1990:32) and in more general terms, refers to how good a system is at doing what it is supposed to do’. (Preece et al. 2002:14)

Learnability relates to the time taken to learn a system. (Shackel 1990:32) According to Preece et al. a key concern is determining how much time users are prepared to spend learning a system’. (Preece et al. 2002:17) Here, the Ten-Minute Rule’ can be applied, that is to say that a novice user can learn the system within ten minutes. (ibid. 2002:16)

Flexibility is a measure of how well the system can adapt to variation in tasks and/or environments beyond those first specified’ and an example in a product might be an option to mute the sound, which may be useful if used in public environments. (Shackel 1990:32)

Efficiency concerns the way users are supported whilst carrying out tasks. For example, an interface can be considered as efficient if common tasks can be completed through a limited number of steps. An example is to utilise one button to access a bookmark index. (Preece et al. 2002:14)

Safety is concerned with protecting a user from undesirable conditions. In this case it refers to avoidance of errors. (Preece et al. 2002:15) For example a quit’ function could be the standard Windows close’ box in the top right hand corner, and as such is distant from other commonly used functions preventing accidental closure of the program. Another example is in providing a confirmation dialogue box before allowing deletion of bookmarks.

Utility is a goal relating to the extent to which the system provides the right kind of functionality’, so that a user can achieve their goals. (Preece et al. 2002:16) One example might be an alphabetical search function which allows searching by word entry or by scrolling through a list.

Memorability refers to how easy a system is to remember how to use, once learned’. (Preece et al. 2002:17) This can be achieved by using meaningful icons and systematic placement of them. Furthermore, options can be structured in a logical way such that knowledge from the real’ world can aid the user. An example is that information about Chile can be accessed through a South America’ link.

Usability goals are coupled with user experience goals. These are concerned with what the interaction with the system feels like to the users’ and focus on systems that are fun, satisfying, enjoyable, entertaining, helpful, motivating, aesthetically pleasing, emotionally fulfilling, rewarding and supportive of creativity. (Preece et al. 2002:18) This coupling leads to trade-offs, that is to say that the outcomes of the goals do not necessarily coincide. For example, engagement with the product may be encouraged by peripheral functions not being easy to use, raising a challenge to the user. This contradicts the usability goal of learnability’. (ibid. 2002:19)

    Does my website look professional enough? Aslo how can i imrove in regards to SEO?

    I recently started my own web design / graphic design agency. I have been building websites for just over a year now so please do not ridicule my work to date – I am still learning…..

    here is a direct link to my site – http://www.tndcreative.co.uk

    My first question is please could anyone reading this post give me some constructive critisism regarding my website. What have I done well, what could I improve and what do you think I need to work on.

    My second question is by looking at my code is there anything I can do to help climb the google ladder in regards to page rank. The site itself has been live for almost 6 months and I am still on page 12/13 for searches such as “Web Design Surrey” “Graphic Design Surrey” etc

    Kind Regards


  2. Creating A Basic Database Website?
    I’ve got a question I would really appreciate your wisdom on…

    Want to create a really basic template that I can duplicate several times for different database websites if that’s possible.

    The database websites ideally would each have:
    •Breadcrumb trail
    •RSS feed for each URL
    •Use mod rewrite so URL’s are search engine friendly

    Something like the following typical hierarchy (3 or 4 tiers):


    Home page -> Links to 20-100 Category pages -> Category pages link to category subpages underneath each category -> (Optional) Then some sites would link to a final “product” page

    For example, one database site I would love to do would be a site about banks in the UK.

    So it would be:

    UK Banks -> Surrey Banks -> Brighton Banks

    Another database site would be about cars and different models/makes:

    Cars -> BMW -> BMW M3

    And so on…

    The only database fields/values that I can think of which would change on each site are the following:

    1.Category anchor text links
    2.Sub category anchor text links
    3.Title Tag – (same as page URL)
    4.H1 Tag – (Same as page URL & title tag)
    5.H2 Tag – (Same as page URL & title tag)
    6.Meta keywords – (Same as page URL & title tag)
    7.Meta Description
    8.Body content – 150-300 word text on category & sub category pages – All content would be very similar throughout the site but use place-holder text that would change depending upon what the page was about.

    Tell me if I’ve got it completely wrong, but from what I understand so far (learning tonight), if I use the same fields in the web design structure, I will just need to update these values on an excel spreadsheet with different data (kept in the same columns) and simply upload that to MySQL for each new database website. The design would be pretty much the same on each site and I could do that myself with Dream Weaver. Therefore, if I can get a template database designed, I could then use that for the other database websites.

    Please let me know your thoughts? Is this all possible or am I not appreciating what a massive task this is?



  3. Is this a good discription I’ve written?
    I’ve designing a postcard to advertise my new web design agency. On the postcard I have space for a short 100 word description and I would like your opinion on the one I’ve written if that’s okay.
    Here it is:

    Thanks for reading it. If you could give me your feedback that would be great. Also, if you think you could improve it or even do a better job, please could you write your version in your answer. Thank you.
    Thank you for answering so quickly ladies! In the final description I have the company name instead of ‘our agency’ at the begriming. I omitted it from my question because I didn’t want to be seen as advertising on Y!A.
    I’ve added an apostrophe to the ‘customer’s’ like one of you said. Grammar and punctuation are my biggest faults, I never get anything 100% right. Thanks so much for the feedback, I really do appreciate it

  4. Don’t capitalize ‘agency’. Make the second sentence shorter, or break into two sentences. Omit “it’s a little known fact that.” Apostrophe in the ‘customers’ (customer’s) before ‘attention’ .

    Pretty good all in all =)

  5. Hey, your website really looks great, i mean it … no need to change anything on design, looks clean.
    The code could be improved by moving out the on-page css to the external css, and also moving out of the way the text/javascript code (make it external so the page body will be near the top)

    Could put more effort on having more pages as in more text/site , but the most important is the lack of promotion for it, meaning very few backlinks.
    A more detailed analysis could be found here:

    For start just try to look at other people pages (same niche) and see where from they got their backlinks and follow their tracks (do a reverse engineering).

  6. where i can find roxy (quicksilver) endless vacation 110 litre luggage? preferably the black and white spots?
    I can find the luggage i want on the roxy website (http://eu.roxy.com/collections/product_detail.aspx?id=6338)
    but i can not find a stocklister that sells it. i have looked all over the web but all they have is different deisgns. i would either like the brown and orange small spots or the black and white large spots designs in the 110 litre endless vacation luggage style?
    i need the stocklister to be in surrey or london

  7. Where can I find a decent web designer in Surrey?
    I’ve been looking for someone to design a website, and preferred if they were based in Surrey. There are so many, how do I know if they’re any good. Any of you have any experience with any web designers in the Surrey area? Freelancer’s probably best as they end to be cheaper!

    Thankyou for any answers.
