Let common sense prevail

Me: “Hello, I’d like to book a flight back to London on Thursday please”.

BA: “Certainly. BA 28. Midnight Thirty Five.”

And that was it. No friendly warning, so close to doing this again.

If I ask for a flight on Thursday, common sense suggests that the fact that the plane is scheduled to depart 35 minutes into Thursday, and I need to be at the airport at 10pm on Wednesday, then it really isn’t a Thursday flight. Not being explicit and clear with this is rude business.

The scourge of Document Driven Design

Documents, or rather words are the scourge of product design. Because words can never convey the true meaning or emotion of what is really required. All to often, software development projects are driven by the documentation – agile projects can be equally guilty of this- driven by words on paper (or card) that convey what the requirement is. Issue #1. Developers don’t read!

Except for a few exceptions, software is all about a user interacting with a system in order to accomplish a goal. Trying to describe that premise in terms of features and functionality is fundamentally flawed as it will be nested in the language of technical implementation, not in the user interaction. “Find” becomes “search”, “buy” becomes “shopping cart”, “check” becomes “validation” and so on. Issue #2. The desired outcomes become lost in a smog of technical jargon.

Solution: Picture Driven Design. Up front. Yeah! I’m all for up front design! A picture tells a thousand words. It has the power to remove ambiguities, clarify the vision, showing what the journey to realise outcomes look like. Start with a day in the life of… scribble out the flow, the user journey. Nothing complicated, boxes and arrows. Then scribble out what the user interface might look like. Done. That’s your up front design. That’s your documentation. That’s your scope. What you do next is up to you, write loads of documents that describe it and produce the software in a waterfall way if you want. I’d prefer you were more lean and adopted agile practices, but whatever you do, start with the picture. I’m convinced it will save much pain later on.

CAPTCHA: a barrier to entry

When a customer starts completing an application or registration form it demonstrates they are committed. It therefore makes sense to pay attention to the usability of that form. But how often is the content of the form considered? Are there content barriers in the form that prevent customers from completing it?

Marcelo Calbucci (Via Luke Wroblewski) describes a barrier that everyone assumes just has to be there so it is not tested: The CAPTCHA. When the team removed the CAPTCHA from the Sampa.com registration form they recorded a 10% increase in conversion rates. Marcelo writes “we created a set of tests and rules that will make us not display a CAPTCHA about 99% of the time” (interestingly when I looked at the page I got the CAPTCHA). A 10% increase in conversion is not insignificant, and probably more than outweighs the additional effort to implement an alternative solution.

Banks don’t want you emailing their staff

You went to the local branch of your bank and spoke to a really helpful person there. In the few minutes you were with her you established a relationship with her. You felt comfortable and confident that she would take ownership of your request. But before she could deal with your query, disaster! You left some critical information at home.

Can I email it to you later you asked her?

Silly question.

Have you ever tried emailing someone in the branch network? Chances are the frontline staff don’t have external email. What sort of business is it that doesn’t give its staff email and the ability to communicate on a personal level with its customers? the same sort of business that has centralised all its customer contact and put it behind IVR.

So you give up on email.

Can I give you a ring with the details later you asked her?

She shakes her head. She doesn’t have a number. you see the branch doesn’t give out its number to the public. Go through the 0845 central switchboard, and let someone in the call centre pass a message to the person in the branch. (With no formal process to get this to happen, good luck if your messages ever gets passed on).

In fact the only way you will probably get a message to the person you talked to this morning is if you send a fax. One step removed from the telex, two away from the telegram.

What is it with the banks that they don’t want their staff to have external email access?
