Rewire the org before you announce it

A living org chart for the power transmission company's HR team. One Excel goes in; an interactive organisation comes out, with spans and layers X-rayed, reorganisations rehearsed on screen and succession gaps flagged before they bite.

The Challenge

Thirty-four org charts, and none of them current

The power transmission company runs transmission projects, conductor and cable plants and an upgrade business across India. People move between projects every quarter. HR's picture of who reports to whom lived in slide decks that went stale the week they were sent.

Charts as slides

Every BU kept its own PowerPoint org chart. Thirty-four versions were in circulation, each drawn by hand and out of date within weeks.

Layers nobody chose

Some plant teams sat eight layers below the CEO, and a quarter of managers had one or two reports. Nobody could see it, so nobody fixed it.

Reorgs on a whiteboard

Each restructuring took weeks of redrawing. Leaders saw one option, late, with no view of the cost, the layers or the people affected.

Succession in a drawer

Successor lists sat in a separate file. When a project director resigned, HR found out on the same day that there was no ready-now cover.

HMC Approach

From 34 slide decks to one living organisation

Built with the power transmission company's HR leadership and HR business partners, starting from an HRMS extract and the decks they already had.

Select a step to see what happened.

Discover · Count the charts

We gathered every org chart in circulation and compared them with the HRMS.

  • Found 34 versions across BUs, with conflicting reporting lines in a fifth of them.
  • Mapped which HR decisions need an org view: reorgs, spans, succession, hiring.
  • Agreed what must stay private: pay, ratings and risk flags by role.

Deliverable: Org data audit and use-case list.

Design · One Excel, one truth

A single sheet that any HRBP can maintain: one row per person.

  • Columns: ID, name, role, business, reports-to, location, since, grade.
  • Span-health rules agreed: under 3 is narrow, 3 to 10 is healthy, over 10 is wide.
  • Critical-role list and successor readiness added as optional columns.

Deliverable: Org data template and design rules.

Build · The living org

A single HTML file that turns the Excel into an interactive organisation.

  • Org chart with search, filters and detail cards; Excel in and out.
  • Spans-and-layers X-ray, reorg sandbox and succession bench view.
  • Built with Claude as the coding partner; plain-English "Ask the org" questions.

Deliverable: Org Studio (single HTML) and data template.

Adopt · HRBPs own the sheet

The chart refreshes the day the Excel changes.

  • HRBPs update their BU tab; the chart rebuilds on upload.
  • Every reorg proposal now arrives with its sandbox scenario attached.
  • Quarterly talent review runs on the bench view.

Deliverable: Refresh routine and reorg review template.

Scale · Live from the HRMS

From a monthly Excel to a daily feed.

  • HRMS export replaces manual updates.
  • Role-based views: leaders see their own tree, HR sees all.
  • Cost and diversity lenses added with access controls.

Deliverable: Integration roadmap and access model.

The Solution

Org Studio: see it, ask it, rewire it

Four connected views built on one Excel. Everything below is live: click, search, filter, ask a question, rehearse a reorg. Upload your own sheet and every view rebuilds.

01 · Living org chart

The whole organisation, from one Excel

Click a card for detail, the round button to open a team, drag to pan, scroll to zoom. Colour the chart by business, span health, flight risk or tenure.

Click a card · drag to pan · scroll to zoom

All people, names and figures are synthetic and illustrative; no the power transmission company employee data is shown. The download gives the same Excel template HR maintains.

02 · Ask the org

Questions in plain English, answers on the chart

Type a question or tap one below. The answer names the people, and one click lights them up on the org chart above.

Try “Who reports to the CFO?” or “Critical roles with no successor”.

How it reads your question

The question becomes a filter on the org data. The filter is shown, so HR can check the logic before acting on the answer.

// waiting for a question

Rule-based demo. In production Claude reads the question and the org data, with access controls by role.

03 · X-ray & reorg sandbox

See every span and layer, then rehearse the reorg

The radial view puts the CEO at the centre and each layer on a ring. Switch on a scenario, or move a team yourself, and watch the organisation re-form with its layers, spans and management cost.

Impact

Span distribution · dashed = today

No changes yet. Today's organisation is shown.

Span health: under 3 direct reports is narrow, 3 to 10 healthy, above 10 wide. Management cost uses illustrative grade-based CTC.

04 · Bench strength

Which critical roles would leave a hole tomorrow?

Every leadership role plotted by the incumbent's flight risk and the strength of the bench behind them. Top-left is safe; bottom-right needs action now. Toggle to see the bench after the talent review.

Selected role

Click a bubble to see the incumbent and their successors.

Flight-risk and readiness scores are synthetic. In production they come from the talent review, with access limited to HR and the role's line manager.

Impact Dashboard

A flatter organisation, and HR hours back

With narrow spans visible, the first delayering round merged teams that had one or two reports. And HR stopped spending days redrawing slides.

Key Takeaways

What any HR team can borrow

01

One sheet beats thirty-four decks

When the org chart is generated from data HR already owns, it stays current without anyone redrawing a box.

02

Spans and layers are design choices

Once narrow spans and deep layers were visible, leaders fixed them in a quarter. They had simply never seen them.

03

Rehearse the reorg on screen

Seeing the layers, cost and people affected before the announcement turned reorg debates into choices between options.
