  In the domain of software engineering, our efforts as researchers to advise
industry on which software practices might be applied most effectively are
limited by our lack of evidence based information about the relationships
between context and practice efficacy. In order to accumulate such evidence, a
model for context is required. We are in the exploratory stage of evolving a
model for context for situated software practices. In this paper, we overview
the evolution of our proposed model. Our analysis has exposed a lack of clarity
in the meanings of terms reported in the literature. Our base model dimensions
are People, Place, Product and Process. Our contributions are a deepening of
our understanding of how to scope contextual factors when considering software
initiatives and the proposal of an initial theoretical construct for context.
Study limitations relate to a possible subjectivity in the analysis and a
restricted evaluation base. In the next stage in the research, we will
collaborate with academics and practitioners to formally refine the model.
