Building knowledge management (KM) infrastructure involves reuse and refocus of several existing infrastructure components, and awareness around future visions and conditions of infrastructure. We present a community perspective using a staircase metaphor for conceptualizing government supported KM infrastructure and services. Additionally we illustrate a model for government's role in providing and leveraging infrastructure components from all tiers of government. With examples, we build a case for adding diffusion of innovation characteristics, and features from innovation networks analysis in KM infrastructure. Observability and trialability are important to knowledge acquisition, while compatibility are central to knowledge application, packaging, and creation. Ease of use, and perceived usefulness affects knowledge use in all its forms.
