{\bf How do we make sure the result is right?}

Specific focus items:

$\bullet$ Cross-community review of ideas with large impact:\\
- Do we catch on in time that things are happening?\\
- Does anyone read Last Calls anyway?

$\bullet$ Architectural insight:\\
- Are we getting the right clues
into the IETF process at the right time?\\
- Is the IAB helping do that? Can it do better?

\end{slide}

\begin{slide}{}
{\bf Possible topics with large impact?}

IPv6 (did we get this right?  mixed opinions)\\
IDN (potential danger?)\\
Instant Messaging (potential danger?)\\
Middleboxes\\
QoS (we have router per-hop behaviors, but not end-to-end QoS)\\
Multicast (we have multicast in routers, but not end-to-end multicast)\\
AAA/Diameter (did we get this right?)\\
IPSEC/IKE (did we get this right?)\\
SIP (largely a success, with further simplification in progress?)\\
MPLS (we didn't get this right)\\
OPES (still in progress)\\
PPP, DHCP, MIME (we got *something* right here) \\
Routing (did we get this right?)\\

\end{slide}

\begin{slide}{}

$\bullet$ How well has the IETF done on these topics?\\
- What about cross-community input?\\
- What about architectural input?

$\bullet$ The reason to ask the questions is ultimately to learn from what has
and hasn't worked in the past.

\end{slide}
%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%
\begin{slide}{}

$\bullet$ Have we totally blown anything?

- IDN and Instant messaging have been suggested as things
that we might blow in the future.

$\bullet$ Things that we didn't do that we should have?

$\bullet$ The perception of the average IETFer on how well the IETF
has done in terms of getting the result right?

\end{slide}
%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%
\begin{slide}{}

{\bf What about the smaller topics?  How well have we done?}

$\bullet$ PANA.

$\bullet$ Transport:  SCTP, CM (Congestion Manager).

$\bullet$ ...

How does one get cross-community review, and architectural input,
on these kinds of topics?  Is it needed?

{\bf Possible mechanisms for cross-community review and for architectural
input:}

$\bullet$ BOFs and Interim Reviews?

$\bullet$ Problem statements and architectural statements?

$\bullet$ Roadmap Working Groups, for working on the larger picture?

$\bullet$ Panels of reviewers?

$\bullet$ Design reviews during plenary sessions?

$\bullet$ A better understanding, for each topic, of the impact (or lack
of impact) on other areas and layers, or on other things within the area?
(Some things need cross-community review, and some things just don't...)
