Identify Customer Needs

Step 1. Gather Raw Data From Customers

Interactions with Customers

Interview with Fellow Student Rosa Mitsumasu Heredia

Interviewer: Benjamin Johns Date 18 September 2007, Java Wally's

Customer needs investigated:

The customer for this product is significantly different than a typical customer in the United States. In the United States it is obvious that we take clean water for granted. Also these customers may not be able to go to Lowes or Home depot to pick up parts to repair or fabricate their own system. The major needs of the customer as described by Rosa are listed below

  1. Project be able to be built in the community
  2. Natural resources available
  3. Delivery of the project
Insights

Rosa felt that the goal of the sustainable energy was to improve the quality of life for a segment of people somewhere, protect the environment using sustainable techniques, and as an added bonus to improve the economics in an area by creating a project that they may be able to produce and sell. The pasteurization project would be a second generation project; therefore we would be improving the designs of the previous group. One major way, Rosa felt, to improve this project would be to implement this project to a greater degree in the area. She felt that having a person on my team who has knowledge of the community in which I could implement a system of this kind would be of utmost importance. Second generation projects have a chance to build upon the work of the previous generation and the most important of this improvement may be making contacts and implementing a system in a rural area.

Interview with Linette Koren KGCOE/CIMS Liaison/Librarian

Interviewer: Benjamin Johns Date 19 September 2007, Library

Linette showed me how to navigate the library's interlibrary loan systems and spoke about her favorite journals.

She pointed me in the direction of these journals, conference papers:

  1. ISI proceedings
  2. Compendex (turn on inspec)
  3. Science direct
  4. Pub Med
  5. Enviromental Sciences and Polution
Insights

Linette made me aware of the fact that the library has recently increased its collection of water borne illness books because the freshmen required reading was about the outbreak of cholera in Britain.

This is a great place to include an affinity diagram constructed in collaboration with the customer, a fcous group, or peer students, as a graphical representation of raw data associated with customer needs.

Step 2. Interpret Raw Data in Terms of Customer Needs

  1. Safely pasteurize enough H20 for one typical family in a Venezuela.
  2. Cheap to maintain: Must be affordable to upkeep for typical family of interest.
  3. Cheap to produce: Unit must be cheap enough to get into hands of customer.
  4. Cheap to use: Should have no consumables and no direct cost to run.
  5. Easy to use: Customer will likely have limited educational background, may be illiterate, and probably won't know English.
  6. Easy to assemble: If possible, end customer should be able to set up unit themselves.
  7. Easy to maintain: Again, should be serviceable by end customer.
  8. Easy to safe: Device must not pose direct health risk to end user (no sharp edges, hot surfaces, excessive glare, etc.)
  9. Environmentally Friendly: Should be made of materials and employ processes that will not be harmful to the environment.
  10. Distributable: Should be easy to get into end user's hands.
  11. Tamper Resistant: Should resist undesired repurposing.
  12. Solar: Must be powered by solar energy, per project guidelines.

Step 3. Organize the Needs into a Hierarchy

After listing the needs in list order here, this is a great place to include an objective tree as a graphical representation of your interpretation of the customer needs.

Step 4. Establish the Relative Importance of the Needs

Needs Summary
