01Why a decision system

Ninety seconds on what a decision system is for.

Before the details: why marketing needs one place where data, creative and media meet the decision. Sound on.

dcsn.one, a Decision System for CMOs and CEOs by Group One1:37, sound on

dcsn.one by Group One is a decision system for CMOs and CEOs. It measures how your marketing decides across data, creative and media with the Decision Maturity Index, simulates how your organisation can work tomorrow, and maps the implementations that get you there, with an action plan for every stage.

02What runs underneath

Three pillars. Nine engines. One decision system.

Composable, not a black box. Each engine gathers the solutions, products and services that serve one kind of decision, so you switch on only what that decision needs.

Data

Every decision starts here.

Three engines turn raw inputs into evidence.

Synapse

The data foundation: cloud data platforms, composable CDP, GA4 and app measurement, dashboards and audits that put every source into one trusted picture.

Cortex

Models that predict before you spend: marketing mix modelling, propensity and lifetime value, smart segmentation, attribution you can stand behind.

Neuron

Eyes on the market: brand tracking, consumer journey and campaign effectiveness research, competitor and real-time monitoring, ambassador research.

Creative

Ideas that move people.

Three engines sharpen emotional signal.

Pulse

Strategy before production: communication strategy, consumer insight management, category trends and competitive benchmarking.

Flow

Creative in every form: communication platforms and big ideas, data-driven and AI creative, video, rich media, motion design, production at scale and creative operations.

Reso

A voice that carries: social media, influencers and creators, PR, advocacy and content, brand strategy and long-term communication platforms, omnichannel campaigns.

Scale

Execution that compounds.

Three engines turn ideas into momentum.

Lift

Growth in media and commerce: value-based bidding, audience activation, Shopping and marketplaces, native reach, visibility in AI search.

Shift

Budgets that move with the facts: attribution beyond last click, TV-to-online measurement, automated YouTube buying.

Orbit

New markets without new chaos: content localisation and roll-out, marketplace sales across Europe.

03A glimpse of the system

How it works

1/ Interview, human or agent

Led by a human or by the agent.

Human in the Lead: our consultant runs the interview, or the agent does when that suits you. It asks, listens and writes the facts down, any time.

2/ The CMO Pulse check

32 areas. Facts, not opinions.

Every axis has named states, the same for every company. You pick what is true today, or say you do not know.

3/ Stage 2, the specialists' grid

Your specialists add the detail.

The stack as it is, how data moves between systems, what breaks when a number looks wrong. One area at a time, with “don't know” allowed.

4/ The report

Your score, decision by decision.

Eleven decisions scored per 100, the key ones marked. Where the board's self-image and the specialists' facts differ, the report says so.

5/ Tomorrow, phase by phase

Tomorrow, told by the people who will decide there.

Pick a phase and hear the CMO, the area owner and the specialist describe how their work changes.

6/ The path to better decisions

Real implementations, step by step.

Each step on the road has its place, its time to effect and an action plan, whoever you work with today.

A deep dive into our decision system

Three steps, one coherent process.

Take the DMI to see where you stand today, then let our algorithm simulate how your business reality shifts as your decision maturity grows. Map the real implementations that will get you there: step by step, built around your goals and existing stack, with a ready action plan for every stage, whoever you work with today.

1Step 1See where you stand today

04Your DMI score, today

Know exactly where you stand before you transform.

The Decision Maturity Index scores how your organisation decides across 32 areas: from a 25-minute pulse with the CMO to a fact-based deep-dive with your specialists. You get a score, a market band and the three priorities that move it most.

2Step 2Plan for tomorrow

05Tomorrow

See the change before you make it.

Pick how far you want to go: a first step, a solid move or a leap, in each pillar. The engine moves real decision axes one state up and shows which areas change, by how much, and who in your organisation starts deciding differently. Then the path puts solutions on it, phase by phase.

  • 1Tomorrow is computed, not promised: every point comes from a concrete change in how a decision is made.
  • 2People, not slides: the CMO, the area owner and the specialist each tell what their day looks like after the change.
  • 3The path orders what closes each gap by fit and payback: Crawl, Walk, Run, Fly.

06 The path and the brief

Where the road begins.

Two things the report opens into, shown below on demo data: a transformation path that explains its steps, and a goals brief drafted from the facts.

The transformation path

One line that shows what each step changes.

Each step is one change, ours or yours, and the line shows what it adds. The path plays on its own and pauses at three steps our solutions deliver.

The goals brief

Your facts, our questions, your decisions.

Human in the Lead. The DMI is your decision selfie: we ask the right questions, you catch what matters. Facts, not opinions, and we are not afraid to challenge what you do.

2We ask, you decide. Confirm, rewrite or reject every goal.

07What we implement

Every gap has something that closes it.

solutions sit on the path, matched to the areas where you lose the most. The catalogue is behind sign-in; four examples below.

The plan

From the confirmed goal to the step that delivers it.

For each step the plan shows the goal it serves, what must change in daily work, the recommended package with what it requires and what extends it, and the result on the area. Choose another way and the plan recomputes.
