Mom Test Notes

Chapter 1: The mom test

Bad/Good Questions

Bad: "Do you think it;s a good idea?"
Fix: You might ask them to show you how they currently do their job. Talk about which parts they love and hate. Ask which other tools and
processes they tried before settling on this one. Are they actively searching for a replacement? If so, what’s the sticking point? If not, why not? Where are they losing money with their current tools? Is there a budget for better

	var events = {
	events: {},

	if (typeof console === "undefined" \|\| typeof console.log === "undefined") {
	console = {};
	if (alertFallback) {

	alert(msg);
	};
	} else {
	console.log = function () { };
	}
