I see many of the same issues you are seeing, but my analysis is a bit different. Organizations are prone to seek decentralization where there is centralization and centralization where decentralized. Back when each agency worked more on its own, with less centralization, there were significant issues too. One of those issues was that each agency bombarded church members with lots of mailings, each spending plenty to compete with the others. "We" as the denomination were giving money to agencies so they could each compete with the others for us to give them more money to compete with each other. This still happens, of course, but it has been good to have some better centralization in this regard.
There were other issues then too, some of which I saw too closely that are hopefully in the past and that I will not indicate here. Also, I can say with certainty that there were illegal activities taking place where I know the parties were told the activities were illegal and continued the practices knowingly and on purpose. A whistle blower could do nothing other than work like crazy to eliminate the illegal behavior across all of the agencies in a way that the denomination spent a lot more money than if there had been an ED at the time. It was so decentralized that I doubt you can find anyone who would know what I am talking about (but you can ask me offline). So, while I am sure that there are some centralized functions that could benefit, even if only from a Hawthorne type of effect, from decentralization, I would not be too quick to jump toward really significant decentralization to the local classis.
Classes have some of the biggest baggage in the denomination and often have significant differences of opinion within a loosely-formed, sometimes dysfunctional, group. For example, there can be churches that favor launching new churches and others that insist on very strict adherence to xyz within their classis in such a way that would hamper a new church. Some have decided against women and others for women while the classis then has the authority not to seat women. It might shock some to know that there are still many all-male classis in our denomination even in 2011.
I suggest that instead of going the route of putting more in the hands of classis, we could do something signficant with potentially much better results by doing what many companies do and eliminate the "middle management." So, I'll suggest that any decentralization be to the local churches. Churches might decide to work with another church, but if they get a denominational grant, for example, they could work with other churches of a like mind, without a classis in the middle. Local churches already have a means to function that works for their organizational culture. The denomination can help with economies of scale and we could completely eliminate classical interference (many new churches have stories about how a classis has tried to trip them up, for example) by eliminating classes or reducing their role rather than expanding it.
I do not see this as cut and dried, but I would favor a focus on local congregations, possibly with regional assistance coming from the denomination. This approach aligns with the healthy church initiative and would be good if there were a home missions push to encourage churches to birth daughter churches, for example. If we focus on making our churches and our denomination healthy with our limited resources, we could have less, rather than more, handled by the "middle management" of our classes. I realize this is a drastically different approach and that you are tasked with doing what might be considered to be a marketing function for classis with this blog, so this is likely the opposite direction you want to go, but what do you see as the downside to eliminating classes altogether? [Yes, I know it would be radical and we are a slow-moving organization, but sometimes it is worth doing an apple-cart upset.] If we do not go that route, then we really need to do something to make it much easier for a classis to get something done, and, of course, we must end the discrimination against women for some of us to have any interest in putting more money in the hands of these organizations. Make sense?



Got a good chuckle out of your intro...
great points, worth a lot more discussion...
definitely agree with the quiet shift of resources to more local ministries. I know we (my husband and I) feel the tension when our church's ministry shares are short, but we feel led to support the local prayer ministry I'm involved with instead.
