From Spreadsheets to Strategy: A Telco's S&OP Journey

How a telecommunications provider rebuilt Sales & Operations Planning from a reactive, siloed process into an integrated business planning capability — and what typically goes wrong along the way.

Why S&OP is Different (and Harder) in Telecommunications

Sales & Operations Planning (S&OP) is often first built in FMCG or manufacturing, where the core planning problem is matching demand to a relatively stable production line. Telecommunications providers face a more complex version of the same problem: demand spans device sales (handsets, routers, IoT hardware), network capacity (fixed and mobile), service activations, and installation labour — each with different lead times, different suppliers, and different constraints.

A typical mid-sized telco planning function has device demand forecast by a commercial team, network capacity planned by engineering, installation capacity managed by field operations, and finance running a separate revenue forecast — often with limited connection between them. This is the starting point for most S&OP transformations: not an absence of planning, but an absence of shared planning.

The maturity model below reflects a widely used four-stage framework (adapted from Oliver Wight and Gartner's IBP research) and is the lens we use to diagnose and sequence S&OP transformations.

The Four Stages of S&OP Maturity

Stage 1 Reactive / Fragmented , No formal cross-functional process; planning happens in silos; decisions made in firefighting mode when problems surface. Disconnected spreadsheets, email

Stage 2 | Rebranded / Basic, A monthly meeting exists and is called "S&OP," but lacks disciplined inputs, weak data integration, inconsistent attendance, Shared spreadsheets, basic BI dashboards

Stage 3 | Integrated / Tactical , Structured monthly cycle with demand review, supply review, and reconciliation steps; clear data inputs; forecast accuracy tracked as a KPI Planning software, integrated demand/supply data

Stage 4 | Integrated Business Planning (Strategic) S&OP is financially integrated, scenario-based, tied to the annual strategic plan, and used by the executive team to make trade-off decisions , IBP platforms, scenario modelling, rolling forecasts

Most organisations don't move through these stages by installing new software. They move by fixing governance, accountability, and meeting discipline first — technology is what stabilises the gains, not what creates them.

Stage 1: Reactive and Fragmented

What it looks like

At the outset, our client telco had no single forecast. Commercial teams forecast device volumes based on promotional plans. Network engineering planned capacity on a rolling 18-month capital cycle, largely disconnected from in-year demand shifts. Field operations scheduled installation crews based on historical run-rates, not forward demand. When a promotion drove a spike in new connections, installation backlogs blew out and customer complaints spiked — a pattern repeating every quarter without anyone owning the root cause.

Common roadblocks at this stage

No single source of truth for demand. Three teams, three forecasts, none reconciled.
No forum for cross-functional decisions. Problems were escalated ad hoc to whichever executive was available, rather than resolved through a standing process.
Planning treated as an IT/systems problem, when the underlying issue was governance and process design.

What typically needs to happen first: the project charter

Before any meeting cadence or forecasting methodology is introduced, a project charter should be agreed at the executive level. This is the single most commonly skipped step — and the reason many S&OP "restarts" fail a second time. An effective charter for a telco S&OP build defines:

Executive sponsor — typically the COO or Chief Commercial Officer; someone with authority over both commercial and operations decisions.
Scope — which product lines and business units are in scope for the first cycle (recommendation: start with one segment, e.g. consumer mobile/device planning, before expanding to enterprise or fixed-line).
Objectives and success metrics — e.g. forecast accuracy improvement, reduction in installation backlog, reduction in expedited freight/logistics costs.
Governance structure — who sits on the S&OP steering committee, and their decision rights.
Timeline for maturity progression — realistic milestones (Stage 2 in 3 months, Stage 3 in 9–12 months, Stage 4 in 18–24 months is a typical pace for a mid-sized telco).

Without a charter, S&OP is frequently perceived as "a planning team initiative" rather than a business-wide operating rhythm — and loses executive attention within two or three cycles.

Stage 2: Rebranded but Under-Powered

What it looks like

The client introduced a monthly meeting labelled "S&OP." On paper, this looked like progress. In practice, the meeting was a status update, not a decision-making forum. Attendance was inconsistent — commercial leaders frequently sent delegates without decision authority. Data was pulled manually from multiple systems the week before, introducing delays and version-control issues. Decisions made in the meeting were often quietly reversed afterward because the people who needed to be accountable for them weren't in the room.

Common roadblocks at this stage

Wrong people in the room. Meetings populated by analysts and mid-level managers rather than the decision-makers who can commit resources or approve trade-offs.
No pre-work discipline. Data prepared reactively rather than following a fixed weekly/monthly cadence, so meetings become data-review sessions instead of decision sessions.
Ambiguous ownership. No one individual is accountable for the demand number, the supply/capacity number, or the reconciled plan — so when the forecast is wrong, there's no clear owner to improve it.

Getting stakeholder attendance and accountability right

This is where most telcos either build lasting momentum or quietly let the process die. Three changes typically resolve it:

RACI by meeting, not just by role. Each of the four core S&OP meetings (below) should have an explicit Responsible/Accountable/Consulted/Informed mapping — not a general org chart, but a meeting-specific one, because the same person may be a decision-maker in the demand review and only "informed" in the supply review.
Attendance is a governance issue, not a scheduling issue. The executive sponsor should set an explicit non-delegation policy for the reconciliation and executive S&OP meetings — delegates can attend but cannot make commitments on behalf of their function.
Every attendee understands their specific input and output, not just that they're "invited." At this stage, the client introduced a one-page meeting charter (distinct from the project charter) for each recurring meeting, specifying:
- What data or decision each attendee is expected to bring into the meeting
- What decision or output they are expected to leave with
- Who is accountable for actioning it before the next cycle

Stage 3: Integrated and Tactical

What it looks like

By this stage, the client's demand, supply, and reconciliation meetings were running on a fixed monthly calendar with consistent attendance. Forecast accuracy (measured by MAPE — Mean Absolute Percentage Error — by product segment) became a tracked KPI reported at each executive S&OP. Data flowed from source systems into a shared planning tool rather than manual spreadsheet consolidation, cutting meeting prep time significantly and — more importantly — removing the "whose number is right" arguments that had dominated Stage 2.

Common roadblocks at this stage

Process fatigue. Once the initial urgency fades, meeting discipline can slip without active governance — the executive sponsor's continued attendance matters more here than at any other stage.
Over-indexing on forecast accuracy at the expense of decision quality. Some organisations optimise the forecasting number without improving the actual decisions made from it (e.g. capacity investment timing, promotional planning). Tracking "decisions made and actioned" alongside forecast accuracy is a useful counterbalance.
Demand planning still siloed from network capital planning. Telcos in particular often keep multi-year network capex planning separate from the monthly S&OP cycle. Bridging this — even informally, via a quarterly capacity-demand alignment session — is typically the bridge into Stage 4.

Demand planning discipline at Stage 3

A mature demand planning process for a telco typically layers three inputs rather than relying on a single method:

Statistical baseline — trend and seasonality drawn from historical connection/device data.
Commercial input — known promotional activity, pricing changes, competitor intelligence.
Market/macro adjustment — population growth in network footprint areas, handset upgrade cycles, regulatory changes (e.g. mandated network expansions).

The output is a single consensus forecast, not an average of three competing ones — the demand review meeting exists specifically to reconcile these into one number the business commits to.

Stage 4: Integrated Business Planning (Strategic)

What it looks like

At full maturity, S&OP stopped being an operations-and-commercial process and became a business planning process. Finance fully integrated the plan — every reconciled operating plan now carried a financial P&L and cash flow view, not just volumes. Scenario planning became standard: the executive S&OP team routinely reviewed two or three demand/capacity scenarios (e.g. base case, aggressive promotional case, network delay case) with pre-agreed response plans for each, rather than reacting after the fact. The planning horizon extended from a single operating month to a rolling 18-month view, directly informing the annual strategic and capital planning cycle.

What changes structurally at Stage 4

S&OP becomes IBP in practice, even if the name doesn't change — finance sits at the table as a full participant, not a downstream reporting function.
Capital allocation decisions (network expansion, warehouse/logistics investment) are made through the same governance forum, rather than a separate annual budget process disconnected from monthly operating reality.
The executive team uses the process to manage risk, not just supply. Scenario planning around regulatory change, supplier disruption, or competitive activity becomes a standing agenda item.

Common roadblocks at this stage

Cultural, not technical. By Stage 4, the barriers are rarely about data or tools — they're about executives being willing to make binding trade-off decisions in a structured forum rather than informally outside it.
Sustaining momentum through leadership change. S&OP maturity gained over 18–24 months can regress quickly if a new executive sponsor doesn't inherit the same commitment. Embedding the process into formal governance (board reporting, executive KPIs) protects against this.

Total: roughly 18–24 months from a standing start to a genuinely strategic, integrated planning capability — though meaningful operational improvements (reduced installation backlogs, improved forecast accuracy, fewer expedited freight costs) are typically visible well before full Stage 4 maturity, often within the first two quarters.

Frequently Asked Questions

What is the difference between S&OP and Sales & Operations Execution (S&OE)? S&OP operates on a monthly cycle and focuses on medium-term planning decisions — balancing demand and supply 3 to 18 months out. S&OE is a weekly or daily process focused on executing against that plan and resolving near-term exceptions. Mature organisations run both, with S&OE issues escalating into the monthly S&OP cycle only when they represent a structural gap.

How long does it take to move from Stage 1 to Stage 4 maturity? For a mid-sized telco, a realistic timeline is 18 to 24 months, assuming consistent executive sponsorship. Organisations that skip governance and charter steps to "move faster" typically stall at Stage 2 and require a restart.

What is the most common reason S&OP implementations fail? Lack of stakeholder accountability — specifically, decision-makers delegating attendance at reconciliation and executive S&OP meetings, which removes the forum's authority to make binding trade-offs. Technology and forecasting method are rarely the primary point of failure.

Who should own the S&OP process in a telecommunications company? Day-to-day process ownership typically sits with a Planning Manager or Head of Demand Planning, but executive accountability must sit with a sponsor who has authority across both commercial and operations functions — usually the COO or Chief Commercial Officer — since the process exists to resolve cross-functional trade-offs neither function can resolve alone.

What is a project charter in the context of an S&OP implementation? A project charter is the founding governance document for an S&OP transformation, defining the executive sponsor, scope, success metrics, governance structure, and maturity timeline before any meeting cadence is introduced. It is the most commonly skipped step in unsuccessful implementations.

The Takeaway

S&OP maturity isn't a software rollout — it's a governance and accountability rebuild, sequenced deliberately across roughly four stages. The organisations that succeed treat the project charter and meeting governance as seriously as the forecasting methodology itself, because in our experience, forecast accuracy problems are very rarely the actual root cause of planning failure — accountability gaps are.
