It’s about engineering the experience to be complete, thorough, and polished at every stage. Devoting time and energy to small things that principles denote gives you instant credibility because it’s the small things that are often picked up by users. I love the Microsoft App guidelines;
- Sweat the details.
- Make using apps safe and reliable.
- Use balance, symmetry, and hierarchy.
- Align your app layout to the grid, the new layout for apps.
- Make your app accessible to the widest possible audience, including people who have impairments or disabilities.
Fluffy. But simple. SWEAT THE DETAILS – Don’t scrimp. Go sell that one to the PM!

- Does It Come Directly From Research?
- Does It Help You Say ‘No’ Most Of The Time?
- Does It Distinguish Your Design From Your Competitors’?
- Is it Something You Might Reverse In A Future Release?
- Have You Evaluated It For This Project?
