A method for managing a user's computing environment on their computer or workstation. The method includes storing a set of files in a memory device accessible via a communications network. Each file includes data such as environment variable values defining a particular computing environment. The method includes providing an environment management engine in a user's home directory of a computer. A shell runs in the computer device to invoke and run a computing environment management engine within the shell. The engine generates a computing environment in the computer based on the computing environment definition in one of the files that is chosen based on a user-provided or otherwise determined job state (e.g., the user is working on a project or a portion of a project that is associated with a job state). The computing environment includes versions of software applications, path variables, and alias definitions.
