Your first paragraph loses the argument: the day has past when IPv6 could become a credible solution to the IPv4 exhaustion problem. Like it or lump it, NAT was the solution to the IPv4 exhaustion problem. Which the exec will learn when he chats up his computer literate buddy before making his decision. I don't think NAT solves the problem in a sustainable way. Sure for managers that are already driven by short-term goals, that's fine however in Africa, we are seeing situations where NAT just doesn't scale. Specifically with the influx of submarine cables, the bottleneck has shifted from 'available bandwidth' to 'NAT' (or strictly speaking NAPT) capacity. If you're an ISP or you make network software, this is a straightforward case to make. There are public sources of IPv6 deployment rate data. You can presume that a similar rate holds among your customers and that the customers who deploy IPv6 will disqualify your product if the product doesn't work with IPv6. Good point. If your business isn't networks, you have a much harder case to make. As another poster noted, the end of IPv4 is not on the radar yet.

My experience has been that this model fail to _sell_ IPv6 to non-technical executives. Non-technical executives have 3 questions you must effectively answer: And the model does explicitly address all three concerns (note I only posted an outline ... the post (How to ‘Sell’ IPv6 to Executive Management – Guidance for Engineershttp://techxcellence.net/2013/03/05/v6-business-case-for-engineers/) gives more detail) 1. What is the real dollar cost of doing the project (including both up-front and currently indefinite ongoing costs of dual stack. And don't forget to price out risk!). Now in the post, I mention cost elements. At a point when you are still trying to convince execs about v6, is it possible to have an accurate value for this cost. Wouldn't cost elements and ball-park amounts be sufficient? Please could you shed some more light on 'Pricing out Risk'? any tools and techniques to do that would be highly appreciated. 2. What is the real dollar cost of not doing the project. (i.e. customers you expect to lose because you didn't do it. Don't suggest that IPv6 will allow you to avoid acquiring more IPv4. That's not yet true and if you say, It will be in 5 years the exec will respond, great, come see me in 5 years.) IPv6 has elements of a disruptive technology (right now it really only addresses the needs of a fringe segment of the market and also is perceived as worse with respect to feature set). The inherent problem with such technologies is that no one knows the real dollar cost of NOT taking action (when concrete data becomes available to support that, it would mean it has already seen market success and so if you still don't have it, you'd be too late.) However, in terms of cost (and risk) of inaction - it really will depend on how your organisation derrives value from the Internet and could run from stalled growth in client and revenue base, inability to retain clients and possible unknown adjacent opportunities that will be enabled by IPv6. 3. What is the opportunity cost of doing/not doing the project. Implicitly they'll also be looking for the answer to a fourth question: Do you know WTF you're talking about?

Hello all, One of the questions I often get asked during after teaching/facilitating and IPv6 session is: Now I know all these tech bits and how they come together, but what are the steps for deploying IPv6? I've often scratched my head because I thought 'that's obvious', however I gave have detailed and have decided to provide a framework that anyone could use and would like to get critiques and suggestions on how to improve this for folks looking how to kickstart their IPv6 deployment project. http://techxcellence.net/2013/01/28/step-by-step-framework-for-planning-ipv6-deployment/ Surprisingly, these are very familiar steps that almost everyone who has done a project in the past can relate to. The steps are: 1. Set Clear Goals for the IPv6 Deployment Project. 2. Identify the List of Tasks Required to Achieve each Goal. 3. Identify Resources Required to Accomplish each Task. 4. Get Management Approval/Sign-off for the Project. 5. Execute the Plan, Documenting Everything as you go. 6. Update Relevant Organisational Processes to Integrate new Capabilities Resulting from the Deployment. These are quite obvious steps, however what each of them means and the thought process required to clarify each is what have detailed. I'd like your comments and also your suggestions on what you can do to move your IPv6 Deployment project from and incomplete pile of unclear stuff to and organised set of tasks that will surely lead you towards a working IPv6 deployment?
