Recommendation Section for Project 1

February 6, 2007

Our group is a little confused as to what the recommendation should include for this first product since we shouldn’t be thinking in terms of solutions yet. Can someone clear this up for us? Thanks



Star importance ratings?

February 5, 2007

In looking through Ulrich and Eppinger, they suggest taking survey results and turning them into ‘star’ importance ratings. Where stars go 1-5 to denote the importance of a need. My question is why take perfectly good numerical data, both raw numbers and percentages, and turn them into stars.
It blows my  psychologist brain to lose that resolution… :smoke from ears:

So, the question is can I just use the numerical and percentage ratings?

Are the Importance Surveys a Part Of Project 1?

February 1, 2007

A students asks: Are we supposed to distribute and analyze the importance surveys in Project 1?

Answer: Yes, the importance survey has to be distributed and analyzed in Project 1. Part d of the project assignment requires that you submit a hierarchical list of primary and secondary needs with numeric importance ratings. You obtain the numeric importance ratings by summarizing the results from the surveys.
The project assignment also says that you are to use Ulrich & Eppinger’s five step methodology for identifying customer needs. Step 4 is “Establish the Relative Importance of the Needs.” This is done by distributing and analyzing the results of the survey.

A question on survey/affinity diagrams

January 31, 2007

OK, Dr G, we have a question. Lisa and I had an exchange over email that we decided needs some arbitration 🙂

I think the survey looks fantastic, but there is just one thing that should be changed.
We shouldn’t be listing every single need that came out of the interviews. We are supposed to do the hierarchical list of needs (comparable to the example we did at the end of class on Friday). We are supposed to put all the needs from the interviews into groups. From there we pull out the 6 – 10 subgroups that represent the majority of the needs, thus reducing redundancy in the survey process


That is just the list of needs that are unique.

I don’t think we are supposed to be ‘narrowing’ the list of needs with the affinity diagramming. If we do that we are just doing the importance ratings for the users, which we aren’t supposed to do.

I’m not saying your wrong, but I don’t want to be speaking for the users when I’m not supposed to.

Reckon we should put this on the blog? 🙂

So, what do you think? All needs in the survey? Just the higher-order needs?
Should we just cut the baby in half?


Project Meetings

January 31, 2007

Dr. Greenstein – on the schedule, this upcoming Monday (02/05/07) is listed for Project Team Meetings. Does this mean you are not expecting to see us in class on Monday? That we should plan to meet on our own during this time?

 Please advise.

Importance Ratings

January 30, 2007

Step 4 of the needs analysis process is “Establish the Relative Importance of the Needs.” (This follows Step 3, where you have organized all of your need statements into a hierarchical list of primary and secondary needs.)

A few points:

1. The example in the book (Exhibit 4-8, p. 64) indicates importance ratings in terms of the number of asterisks. It also provides importance ratings for some needs, but not for others. I want you to use numeric importance ratings, not asterisks. And I want you to obtain importance ratings for all of your secondary needs, as well as any primary needs that have no secondary needs beneath them.

2. The book suggests that importance ratings can be obtained in either of two ways:

(a) relying on the consensus of the team members based on their experience with customers

(b) basing the importance assessment on customer surveys

I require that you use approach (b)!

3. Exhibit 4-9 shows a good design for the survey you use to establish the importance of customer needs. Unless you have a very good reason for deviating from this design, use it. My experience has been that students (and clients) for some reason insist on modifying the scale used in Exhibit 4-9, with unintended and unfortunate results.

4. Although the book doesn’t suggest this, I have found it useful to break down the importance survey data into two groups: the responses obtained from potential users of the product and the responses obtained from the client. I present the mean importance ratings in two columns: one mean for the client, the other for the users (and I label the columns to identify which is which). Please do this in your project.

5. Finally, note that the survey in Exhibit 4-9 asks respondents to identify needs that are unique, exciting or unexpected (i.e., latent needs). Not too many respondents will tend to do this, but you can help the process along by reminding them. Denote those needs that tended to be identified in this way in your hierarchical list with an exclamation point.

RSS feeds

January 26, 2007

Hey everyone,

I just wanted to make a quick post to point out that you can keep up with new posts on the blog through an RSS feed. RSS is real simple syndication, and it allows your favorite aggregator to show you new posts as they come up.

I use Outlook 2007 for my aggregator, but some other, popular methods are:
For those with Google accounts, try Google Reader
Or Downloadable, FeedReader 

So, now you can keep up with all the blog goings-on, without ever leaving your inbox!
