Page 27: Individuals & Organizations

Buying Centre Concept – Who, When, How, Why, What …..

• The buying center - All organizational members that influence the purchase decisionComposition changes from one purchase to the nextIsolating the buying situationRebuy: fewer membersNew task: large and complex

• Composition - can be predicted by analyzing the impact of the purchase decision on different functional areas

• Buying center influencea. Users are the personnel who will be using the productb. Gatekeepers control informationc. Influencers supply information during the product specification and evaluation stagesd. Deciders actually make the buying decision

Influence appears to increase with environmental uncertainty Individuals can change roles depending on the purchase; one individual may play multiple roles; many individuals could assume one role

Page 28: Individuals & Organizations

Questions for the Industrial Marketer

1. Which member takes part in the buying process?

2. What is each members relative influence in the decision?

3. What criteria is important to members in the evaluation process?

Page 52: Individuals & Organizations

“Women’s” market: Facts (cont’d)

• Women directly control 51% of the wealth in the USA, and this will rise dramatically as the baby boom ages. The baby boomers control 70% of all assets

• On average, these women will be widowed at 67, and will most likely survive their husbands by at least 6 and as much as 15-18 years*. During this time they have sole control of the household’s assets.

• What no-one knows yet is what kinds of spending patterns we will see from what is undoubtedly the youngest, healthiest, wealthiest, best-educated, most ambitious group of retirees ever

*Dr. Nancy Dailey, When Baby Boom Women Retire, 1998, p.39.

How they buy I: Women and men are different!

• Vision: focused

• hearing

• Smell: relatively insensitive

• Touch: the most sensitive man is less sensitive than the least sensitive woman

• Are all the way on or in a resting state of 30%

• Info processing: men eliminate

•Vision: peripheral•hearing: discomfort level half that of men

•Smell: more sensitive•People orientation: by age 3 days baby girls exhibit 2x the eye contact of boys

•Are never off, their resting state is 90%

•Info processing: women integrate (women notice the little things …brain difference…the details not right or wrong, just is)

Page 54: Individuals & Organizations

How women buy II: Women and men are different!

independence• communicate to obtain info

•other-oriented•responsibility-oriented•group perspective•pride in team accomplishment•hear a language of connection and intimacy

•communicate to create relationships, encourage interaction and exchange feelings

•write scripts that have many conflicts, many climaxes and many endings

•research facts and opinions (personal network)

Page 55: Individuals & Organizations

How Women buy: Some implications• Women are demanding in making the initial purchase in a category, they

recoup their time investment by staying more loyal to the brand they’ve chosen in subsequent purchase cycles increasing retention rates

Word-of-mouth recommendation is more prevalent among women, they are more likely to recommend to others those brands or salespeople that impress them favorably -- in essence, free marketing of the most powerful kind.

• The big risk: Companies as have found that marketing and service improvements designed to enhance brand appeal among women have resulted in greater customer satisfaction among men as well. The reason? In many respects, women want all the same things as men - and then some. Accordingly, when you meet the higher expectations of women, you are more than fulfilling the demands of men. Experience indicates that men do not abandon

While in many categories, the traditional male targets are saturated, the corresponding women’s segments are untapped and virtually uncontested by competition.

Page 56: Individuals & Organizations

Then add the Boomers: The boomers have the money...

• 70% of all wealth plus multi-trillion dollar wealth transfer by inheritance to come

on apparel with 12% growth rate versus 0.1%• aging, female boomers will control most of the

money or live in dependent poverty
