Strategy Canvas and ERRC Grid

What it is

The strategy canvas is a one-page chart, introduced by W. Chan Kim and Renée Mauborgne, that shows how your offer compares with its rivals across every factor the market competes on. The horizontal axis lists the factors of competition (price, implementation time, feature depth, support model and so on); the vertical axis shows the level buyers receive on each, from low to high. Joining one competitor's scores gives its value curve, and when most curves in a category run in parallel, the canvas exposes a market where everyone sells the same thing at different volumes. The Four Actions Framework then asks four questions of your curve: which factors the industry takes for granted should be eliminated, which should be reduced well below the industry standard, which should be raised well above it, and which should be created because no one offers them. The ERRC grid records the answers in four boxes, so the redesigned curve can be drawn back onto the canvas.

Kim and Mauborgne present these tools inside Blue Ocean Strategy, a wider theory of creating new market space. This entry scopes them narrowly, as a PMM's tool for diagnosing a convergent market and designing a sharper factor profile. Four neighbours in this category answer different questions. A Perceptual Map compares rivals on two buyer-chosen axes; the canvas holds eight to twelve factors at once. Bowman's Strategic Clock fixes its axes at price and perceived value. The Product Differentiation Strategy Framework decides which difference to commit to and embed; the canvas designs the whole profile of where to over- and under-deliver. Category Design names and evangelises a new category; the ERRC grid reconstructs the value factors buyers weigh, with or without a new category label.

When to use it

• Win/loss interviews show buyers describing you and two or three rivals as interchangeable, and deals are settled on discount.
• A roadmap review keeps adding features to match competitors, and nobody can say which existing factors buyers would accept less of.
• You are designing an entry offer for a segment that incumbents overserve (too complex, too expensive) or ignore.
• Leadership asks for a repositioning and you need one picture of where the current offer converges with rivals before anyone writes copy.
• A packaging or new-tier decision needs a view of which factors to strip out, not only which to add.

Ownership

PMM typically builds the canvas: it selects the factors from win/loss, Voice of the Customer and competitive evidence, scores every curve, and drafts the ERRC grid as a recommendation. At a scaled company the decision to reshape the offer sits with the CEO, product leadership or a strategy function, because eliminating or reducing a factor commits roadmap, pricing and sometimes headcount; PMM then executes the positioning, messaging and enablement that follow. At solo or founding-PMM stage, the founding PMM commonly runs the exercise end to end, from factor list to the founder's decision meeting to launch messaging.

How to apply it

1. Fix the scope. Choose one segment and one buying situation, then 3 to 5 rivals or strategic groups (for example "enterprise suites" and "point tools"), plus the status quo if buyers genuinely weigh it. Mixing segments flattens every curve into an average no buyer recognises.
2. Build the factor list from buyer evidence. Pull every attribute buyers mention in win/loss interviews, VoC calls, review sites and RFPs; merge duplicates and keep the 8 to 12 that buyers actually weigh, written in their language. Then add any factor the industry competes on by habit, because rivals advertise it, and mark it: these are the first candidates to eliminate or reduce.
3. Score every curve on one scale. Rate each factor from 1 to 5 for every curve, yours included, using the same evidence sources throughout. Where buyers rate you differently from your own team, use the buyers' rating.
4. Read the canvas. Look for convergence (curves running in parallel), factors where everyone over-delivers relative to buyer importance, and factors buyers raise that no curve addresses. Kim and Mauborgne describe a strong curve as having focus, divergence from rivals and a compelling tagline; if you cannot summarise your current curve in one honest line, it lacks focus.
5. Run the four actions and fill the ERRC grid. Put each factor through the four questions and require at least one entry in every box. A grid with only Raise and Create entries is a feature roadmap, not a redesign, and it raises cost without making the offer any easier to choose.
6. Draw the new curve and test the trade. Plot the redesigned curve, check that it diverges from every rival, then test it with 6 to 10 target buyers: will they accept the reductions in exchange for the raises? A reduction buyers reject is a lost-deal reason waiting to happen.
7. Take it to the decision owner, then translate it. Present the grid with its cost and revenue implications. Once approved, feed the new curve into positioning and packaging, and track three measures: win rate in the target segment, average discount depth, and the share of lost deals citing a reduced or eliminated factor. Re-plot every two quarters with the same sources.
