I was asked to provide some UCD case studies at work, preferrably those from global companies. My colleagues found these interesting: The Cost of Frustration http://www.uie.com/articles/cost_of_frustration/ Gradual Engagement Boosts Twitter Sign-Ups by 29% http://www.lukew.com/ff/entry.asp?1128 Case Study: Fewer Input Fields Increases Conversions ...

Mike Cohn provides a great template for user stories which is used throughout the industry. As a type of user, I want some goal so that some reason. As a customer, I want to pay my bill online so that I do not have to mail it in. As a developer, I want unit tests in place so that I can verify my code is functional. As an enterprise card holder, I want ...

A recent one I've found very interesting (and have mentioned to other clients) is the Waitrose redesign. Huge amount of bad responses from users, online message boards flooded with negative comments, twitter awash with complaints. All this could have been avoided (or at least reduced) by considering the Users first rather than the brand and the style. There ...

Doing more research around this topic I came across this article about User Stories, Use Cases and Scenarios. The article defines the three items, but more importantly at the end of the article it sums it up quite nicely, I think. Information below was written by Nadine Schaeffer from ...

I find it to hard to give a clear recommendation as we do not know as much as you do. But I could imagine the following options might help. Finally you have to decide which suits you best. First describe the general page once - put in a placeholder for each module or elements which has different states according to the user type. After you described the ...

Be careful of advanced search. A lot of products end up having it simply because purchasers (as opposed to users) expect the feature... Particularly in the bibliographic space. Many of the use cases are better served by a faceting system, as this more accurately maps to people's search then refine mode of discovery than using advanced search. Partly ...

(Number of users * Frequency of use * Value of successful transaction)/Development_Cost, where value of transaction could be a number of things, but most common is monetary value. I don't think most UX folks would tell you that you can infer usability, success, or failure from a use case, as a use case is used to inform a functional requirement, not ...

A use case is something the system is used for. That is, a use case is a placeholder for solution of a goal or a method (in GOMS terminology). Like, if you want to make your wireframes "interactive" by bringing them into some kind of presentation tool and adding navigation to clickable areas, a use case is both of the following: user creates interactive ...

I disagree, the terms are somewhat interchangeable. Ivar Jacobson who invented use case modelling initially called them usage scenarios and then settled on use cases. Cockburn and Fowler who have written extensively on use case modelling do not distinguish between the terms other than to indicate that use cases are made up of main scenarios and alternative ...

Interesting question. I have struggled with the same feelings and now that I reflect back on it, I find that I do use scenarios and use cases intertwined with each other. Where my scenarios describe the whole story of basic (wanted) interactions with the system, the use cases describe the story in more detail. So, a way to see scenarios and use cases ...

Thanks for your answer. User journey/scenario/flow won't fit for that, it is too granular. Module variations are interesting. I finally decided to write use cases on the Info Archi. mindmap. For each page I have on the IA, I created a node called use-case where I specify all the combination possible. That way I think I wont need to create wireframes for ...

generic use case != use case about a generic feature Seems to me that your potential user calls features such as "navigation" a generic feature. This is different from requesting a generic use case. Q: Can a use case be about a generic feature? Of course! Q: Can a use case itself be generic? This question would probably lead to discussion, but typical ...

When you say "generic" I think "universal" or "reusable", which is something different than you're getting at, I think. You've also identified that the problem you see is that you're being asked to create a use case with no clear success scenario. I would disagree with that -- you say "such as a user just using the navigation to look around", and to that I ...

You need as many screenshots as necessary to adequately communicate the design to the customer. Though, "screenshot" doesn't necessarily mean an actual screenshot. A hand drawing on a piece of paper is often sufficient. In fact, you almost certainly want something low-fidelity unless the design has specific design constraints. If the screenshot is an actual ...

In the book "Writing Effective Use Cases (Crystal Series for Software Development) from Alistair Cockburn" are some good use case technics and scenarios described. His text-based use case method is very efficient and fast. In addition, I have another link to this topic: http://gatherspace.com/static/use_case_example.html

I think there is one where a user is searching for a topic, but there are a lot of extraneous results from a general search. So I might want to find books about - say - astrological sign Cancer, but not anything to do with the illness. Or I want to find books about John Smith, but not books by ( a different ) John Smith. There are probably a number of use ...

FXquincy, you propably should describe all important aspects of some of your best projects. It may include features description, some sentences about innovative features you add, describe why are they so good, important, easy to use, include before/after comparison, user testing results For visual designer, their works speaks for themselves, but in UX/UI ...
