Day 92 - User Experience Problem Solving

If you want to understand a product's vision, you need to understand what problem the product is solving for, who is the product's user, what is their context, and how you plan to improve the user's experience.

1. Frame the problem by understanding your user's needs, user's anxieties, and business goals.
2. Dig deep and explore many solutions before narrowing the focus of the solution.
3. Prioritize and create a specific plan of action with timelines that address the most important needs.

Day 59 - Time Estimate Formula

Try the PERT formula to help you guesstimate how long those project tasks are going to take. It's a three-point estimate which you can use for estimating costs or time durations.

So you'll take your best guess at filling out the formula

Fill out the "a" - Optimistic time in # of hours
Fill our the "b" - Pessimistic time in # of hours
Fill out the "m" -Most Likely time in # of hours

The 'm' (Most Likely time) is then multiplied by 4.
4m is the weighted average.

Next add those three numbers together:  a + 4m + b
Once you have that result divide that number by 6.

'E' is the result.

You now have your best guess at a time estimate as to how long something is going to take!

------------------

Example.  Lets say you want to calculate how long it's going to take you to complete a wireframe for a simple search bar you're designing.  How long will it take?

E = (a + 4m + b) / 6

8 hours is your optimistic guess
20 hours is your pessimistic guess
12 hours is most likely guess based on your experience

E = ( 8 + 4*12 + 20 ) / 6
So the result is 12.6 hours

12.6 = ( 8 + 48 + 20 ) / 6
