How to create a pie chart in Excel?

To create a stacked bar chart in Excel you should:

• Select the entire data range and click “Insert”
• Click “Charts” select a stacked bar chart.
• Right click on the vertical axis and select “Format Axis”.
• Go to “Chart design” to add title and legend.
• Customize your bar chart and select chart style.

Here’s how you can create a waterfall chart in:

Method 1: Using Built-in Waterfall Chart

• Prepare Your Data – Arrange your data with categories and values.
• Insert a Waterfall Chart – Select your data, go to Insert > Charts > Waterfall.
• Set Totals – Right-click the first and last bars, then select Set as Total.
• Customize the Chart – Adjust colors, labels, and remove unnecessary elements.

Method 2: Using a Stacked Column Chart

• Create Helper Columns – Add columns for base, increase, and decrease values.
• Insert a Stacked Column Chart – Select your data and go to Insert > Column Chart > Stacked Column.
• Format the Chart – Adjust transparency, colors, and labels to resemble a waterfall chart.

When you’re rolling out Zoom Docs (especially in hybrid teams already relying on Google Docs or Notion), you need a safety net in case the rollout tanks performance thinks lag, sync delays, doc loss, or broken collaboration links. A good rollback and comms plan keeps you from panicking when things go sideways.

Rollback Plan

• Define the rollback triggers early
• Set clear thresholds for when to revert:
• Latency > X seconds in doc loading
• Sync errors reported by >10% of users
• Integration failures (Slack, Zoom Meetings, or Drive links)
• Drop in active usage >30% in 48 hours
• Keep dual systems live
• Run Zoom Docs + existing doc platform (like Google Docs or Notion) in parallel for 1–2 weeks.
• Users can migrate back without losing access.
• Data stays in both ecosystems until stability is confirmed.
• Automate data reversion
• Make sure your data sync tools (API exports, CSV backups, or Zoom Workspace integrations) can revert docs to their pre-rollout state.
• If performance tanks, restore from the last known stable snapshot.
• Sandbox rollback testing
• Before full launch, test rollback on a small group.

This ensures when you do hit revert, it’s not chaos — permissions, links, and data consistency are preserved.

Comms Plan

• Tiered messaging
• Execs / IT teams: We’re monitoring latency and sync health closely. A rollback path is ready if thresholds are breached.
• Pilot users: We’re testing performance stability; if we roll back, your content remains safe and accessible.
• All users: We experienced slower performance than expected, reverting to the previous version temporarily while we optimize Zoom Docs.
• Central status updates
• Post updates in a single place (Slack #it-announcements, Confluence, or Zoom Workspace bulletin).
• Include:
• Timeline of the rollback
• Expected duration
• Who to contact for document access issues
• Transparent post-mortem
• After stability is restored, share:
• What caused the regression
• What monitoring caught it
• How the next rollout phase will prevent recurrence
• People trust IT more when they own the issue instead of hiding it.
• Recovery and reassurance messaging
• Once stable again, send a We’re back on track update.
• Highlight performance improvements
• Share metrics
• Invite users to retry Zoom Docs

To export Google Docs logs to your Security Information and Event Management (SIEM) system with least-privilege scopes, you must use a dedicated Google Cloud service account with specific Identity and Access Management (IAM) roles. The overall process involves routing Google Workspace logs into Google Cloud Logging and then exporting a filtered stream of those logs to your SIEM via a Pub/Sub topic.
