Hitoshi, When I say SOA is dead, I mean that (in most organizations) business people no longer believe the hype about SOA. The general attitude is that SOA costs a lot and does not deliver value; therefore, funding for SOA initiatives has dried up in most organizations. This is a tragic development, because all organizations should be working to optimize and improve their applications architecture. (Note, though, that few so-called SOA initiatives were focused on architecture improvement.)
Given tight budgets and increased IT investment scrutiny, IT groups should avoid putting forth proposals for "SOA" and instead focus on developing proposals for concrete services with hard metrics that will demonstrate quantifiable business value with rapid ROI.
