Today the Open Network Foundation was announced promoting a new approach to networking called Software-Defined Networking (SDN). SDN allows owners and operators of networks to control and manage their networks to best serve their needs. For example, instead of treating video and voice like a Microsoft Word document, network operators using the OpenFlow protocol can manage priorities. Through simplified hardware and network management, OpenFlow seeks to increase network functionality while lowering the cost associated with operating networks.  The Board consists of representatives of Deutsche Telekom, Facebook, Google, Microsoft, Verizon, and Yahoo and members consisting of Broadcom, Brocade, Ciena, Cisco, Citrix, Dell, Ericsson, Force10, HP, IBM, Juniper Networks, Marvell, NEC, Netgear, NTT, Riverbed Technology, and VMware.

 

Why Domain Experience Matters for a Product Manager or Product Marketing Manager

In the New York Times article announcing the effort, Silicon Valley start-up, Nicira Networks was mentioned.

As a product manager and product marketing Consultant for the Productside and yesterday learning that a recruiter, Olga Ocon, who specializes in recruiting in product manager or product marketing positions has joined forces with the Productside, I thought I would take a peek at Nicira.

Plus, I have been saying lately that many start-ups ignore having a product manager at their great peril as the founders who have the original “vision” get overrun dealing with fund-raising, recruiting, retention, HR, finance, engineering, manufacturing, business development, marketing, speaking, sales, etc. so no one at the company is performing the vital functions of product management.

And failing to do so the company slowly starts going out of business.  Why you ask?  HP often cites that something like 75% of their business comes from product introduced in the last five years.  On the other hand, one can cite an example of poor product management processes and techniques as we slowly watch it die: Yahoo.

I noticed that Nicira actually lists positions for product management and marketing.  Further poking around reveals that the founder Steve Mullaney is a former product manager (many founders and CEOs are) as is Paul Fazzone their current VP of product management.  Ah…as we frequently see at the Productside, former product managers get the importance of having people focus on product management.  Also, when their product managers product their work products, the Steve Mullaney’s and Paul Fazzone’s know exactly what to do with it.

Looking further at the job descriptions at Nicira it calls for years of networking technology, networking systems, data center networking, compute virtualization, distributed systems, storage, distributed systems, and infrastructure security experience. Which raises a questions us fellow Productsiders have been discussing over the years.

How important is domain experience for the product manager and product marketing manager?

To kick of this discussion I will present my view:

Not important at all and it limits the hiring company’s ability to bring in fresh, new views.

A product manager or product marketing manager who has been in the industry too long and with little other experience, will just tend to repeat the same mistakes and probably not know any other way.

Providing the product manager or product marketing is bright and knows how to learn fast (like has graduated from a top school) it won’t take them more than a few weeks to be an industry expert but with ideas from other markets to bring to bear.

Frequently Asked Questions

Domain experience is helpful but not essential for a product manager. Strong PMs excel at learning quickly, understanding customers, and making trade-offs. With solid product skills and intellectual curiosity, a capable product manager can gain functional domain expertise in weeks—often while bringing fresh perspectives that long-tenured insiders may lack.
A lack of domain experience does not automatically reduce a product marketing manager’s effectiveness. What matters more is the ability to learn buyer problems, translate value, and position solutions clearly. In fact, PMMs without deep domain bias may better reflect how real buyers perceive the product, avoiding insider jargon and assumptions.
Domain experience is most valuable in highly regulated, deeply technical, or safety-critical industries where mistakes are costly. In these environments, prior exposure can shorten ramp-up time. However, even here, domain knowledge should complement—not replace—core product management and product marketing skills.
Yes. Too much domain experience can limit innovation. Product managers or marketers who have spent their entire careers in one industry may unconsciously repeat legacy patterns and assumptions. This “industry blindness” can prevent teams from seeing new opportunities or applying proven ideas from adjacent markets.
Learning speed, customer empathy, structured thinking, and strong communication matter more than domain experience. Product managers and product marketers who know how to ask the right questions, synthesize insights, and apply best practices across industries often outperform domain experts who lack modern product discipline.
