Build vs Buy

@stamplay

There are no small changes.

When you’re striving for quality

@stamplay

Let’s do a test.

In a Yelp-like app, we want to limit the length of a text review in the product to 140 characters,

because we may want to use SMS to send them out.

..that’s a small change, right?

@stamplay

LET’S ADD AN IF-STATEMENT

@stamplay

Think again..

• What happens when the review is above 140 characters?• Do we crop the string, or display an error message to the user?• If we display an error, where does it appear? What does it say?• Who is going to write the error message?• How do we explain to the user why we’re limiting them to 140

characters?• How will these errors look?• Do we have a style defined?• If not, who is designing it?

@stamplay

• Who’s writing the JavaScript?• Does the JavaScript display the same type of error as the server-side

code?• If not, what’s the new style?• How does it behave with- out JavaScript?

..and again..

@stamplay

• Who is going to write this character counter?• Who wants to test it in our target browsers?• Also, where is the count of letters displayed on the screen?• What does the count look like?• The style should change as the user approaches zero characters and

look erroneous at the limit?• Should it stop accepting input at that point?• If so, what happens when they paste something in?• Should we let them edit it down, or alert them?

..and again!

@stamplay

Nothing comes for free.

@stamplay

It’s not free because you’re talking about it.

It’s not free the verifying it was done right.

It’s not free in the communication of doing it.

It’s not not free to carry it forward.

@stamplay

Connect all the things!

THANKS!
