Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs

- 1. Jillian Fluet’s POTW solution
- 2. A B C D E F G H Draw a square and label the line segments so AP=7 BP=35 CP=49 and DP=x. Then drop altitudes from point P to each side of the square. Label the point on AB, E, the point on BC, F, the point on CD, G, and the point on DA, H. P EP, AH, BF have a length of a GP, DH, CF have a length of s-a EP, BE, CG have a length of b HP, AE, DG have a length of s-b 1 2 3 4
- 3. Then use the Pythagorean Theorem to solve for x. Triangle 1: a ²+b² =(35)² Triangle 2: (s-a) ²+b² =49² Triangle 3: a ²+(s-b)² =7² Triangle 4: (s-a) ²+(s-b)² =x² Add the 2 nd and 3 rd triangles together and subtract the sum of the 1 st and 4 th triangles. Then you get: 0= 49²+7²-35²-x² Solve: 0= 49²+7²-35²-x² x ² =49²+7²-35² x² =35² x=35 or x= (35) x=35 because you can’t have a negative length
