Stakeholder Analysis

In performing a product use study the following stakeholders, their needs, and desires were identified and documented.

Usage

Product Use Steps

Bucket and Mop Combination

1) Make a mess

2) Fill bucket with water

3) Add recommended amount of cleaning solution

4) Put mop in bucket

5) Move mop to wringer

6) Wring mop out

7) Mop floor (i.e. move back and forth across desired dirty surface)

8) Repeat steps 4-7 until desired cleanliness is achieved

9) Empty bucket

10) Repeat steps 2-3 as desired

Folding Mop

1) Make a mess

2) Obtain a bucket or container

3) Fill bucket with water

4) Add recommended amount cleaning solution

5) Put mop in bucket

6) Slide wringer towards end of mop over bucket

7) Mop floor (i.e. move back and forth across desired dirty surface)

8) Repeat steps 5-7 until desired cleanliness is desired

9) Empty bucket

10) Repeat steps 3-4 as desired
