Activity Lifecycle Description for Communication in Human-Integrated Industry 4.0 Environments
A simple lifecycle model that makes “what’s happening now” legible across humans and digital executors—scheduled, executing, completed.
Industry 4.0 systems need people, machines, and software agents to coordinate work reliably. A common failure mode is that each participant has a different mental model of “the activity” (what it is, when it starts, what “done” means, what data should exist at each stage).
This chapter proposes an activity lifecycle description for communication in human-integrated environments. The core idea is the 3SAL model, which represents activities in three temporal stages:
- Scheduled
- In execution
- Completed
By structuring activity information around these stages, the model supports clearer instructions, better runtime coordination, and more consistent post-activity traceability.
Key takeaways
- Shared lifecycle structure reduces ambiguity between human and digital executors.
- “Scheduled → executing → completed” creates stable points for data checks and handoffs.
- Better communication models improve not just UI, but the integrity of coordination.
