A Design Doc for Computer Activity Monitoring Software

If you have ever set up application monitoring, you already know the rules for good computer activity monitoring software. Collect only what you need. Tag everything. Alert on trends, not blips. And never log secrets. The same engineering discipline that keeps your services healthy keeps an activity-monitoring rollout from turning into a trust incident. Here is a design doc you can adapt.

Goals and non-goals

GOALS
- Understand where working time goes (focus, meetings, idle)
- Balance workload across the team
- Spot unusual activity on sensitive systems early

NON-GOALS
- Ranking individuals
- Reading private content
- Tracking outside working hours

Writing the non-goals matters more than the goals. They are your contract with the team.

Data model: what gets collected

Field	Example	Retention
active_seconds	24300	12 months
app_category	productive / neutral / unproductive	12 months
website_domain	docs.example.com	12 months
attendance	start/end time	12 months

Note what is missing: no keystroke content, no message bodies, no personal accounts. If a vendor cannot show you an equivalent table, that is your first red flag.

Access control

Treat the dashboard like production access. Employees see their own data. Managers see team aggregates. Only a named admin role sees individual detail, and every view is logged.

Alerting philosophy

Do not page anyone for a quiet Tuesday. Alert on sustained patterns:

alert: sustained_overload
when: active_hours > 9.5 for 3 consecutive weeks
action: manager asks about workload in next 1:1

The action is always a question, never a penalty.

Rollout plan

Design review: share the doc with the team, collect comments.
Canary: run with volunteers for two weeks.
Gradual rollout: expand by team, not all at once.
Retro at 30 days: what did the data change?

Failure modes to plan for

Alert fatigue: thresholds too tight, managers stop looking.
Metric gaming: people keep the mouse moving; fix the incentive, not the tool.
Scope creep: someone asks to add a new data field. Require a written reason and a team announcement.

Tooling

We360.ai activity tracking provides active time, app and website usage and attendance with role-based categories and employee-facing dashboards. It is used by 120K+ users across 10K+ companies in 21+ countries and rated 4.7 on G2.
