The zero-based business review starts from a deliberately uncomfortable premise: if we were building this company from scratch today, with full knowledge of the market, the technology, the competitive landscape and the customer, what would we do differently?
The question is not hypothetical. It is diagnostic. It forces management to evaluate every activity, function, product, customer, geography and process not on the basis of historical momentum but on the basis of current economic contribution.
The Methodology
Activities
List every significant activity the company performs. For each, ask: if we were starting today, would we choose to do this? If not, what would we do instead? If nothing, should we stop?
A company that has been manufacturing a product line for 15 years may continue manufacturing it because it always has. The zero-based question: if we did not currently manufacture this product, would we choose to start today? If the market has shifted, the margins have compressed, the customer base has moved and the capital required exceeds the return, the answer is no. The product continues to exist because of inertia, not because of economics.
Functions
Evaluate every internal function: accounting, HR, IT, legal, quality, procurement, logistics, customer service. For each, ask: if we were designing this function today, would we structure it this way? Would we insource it or outsource it? Would we centralise it or distribute it? Would we staff it at this level?
A finance function with 25 people performing tasks that automation could reduce to 12 is not wrong. It is inherited. The zero-based question forces the evaluation of the current structure against the optimal structure without the constraint of “we have always done it this way.”
Products and customers
Evaluate every product and every significant customer relationship. For each product: does this product earn its cost of capital? Would we launch it today? For each customer: does this relationship generate positive economic contribution after allocating cost to serve? Would we pursue this customer today?
The answers identify the portfolio of activities, products and relationships that the company continues to maintain because of historical momentum rather than current economics.
What the Review Reveals
The zero-based business review consistently identifies three categories of activity.
Strategic necessities: Activities that the company would choose today and that generate returns above the cost of capital. These are the core.
Legacy activities: Activities the company would not choose today but continues because of inertia, internal constituencies or sunk cost attachment. These consume capital, management attention and organisational bandwidth that strategic necessities should receive.
Transformation candidates: Activities that have strategic value but are being performed in the wrong way, at the wrong cost, in the wrong structure. These should not be eliminated but redesigned.
The economic impact of acting on this diagnostic is typically 3% to 8% of total operating cost, released through the elimination of legacy activities and the redesign of transformation candidates.
In Northrop Management performance improvement engagements, the zero-based business review is the foundational diagnostic. It precedes operational improvement because it identifies what the company should stop doing before investing in doing the remaining activities better.
Ashish Chaudhary frames the transformation principle directly: “Transformation does not begin with doing things better. It begins when management questions the accumulated complexity that decades of growth have created. The most powerful question in management consulting is not ‘how can we improve this?’ It is ‘should we still be doing this at all?’”
Questions for the Boardroom
1. If we were building this company today, which of our current activities, products, functions or customer relationships would we choose not to have?
2. What is the total cost (direct, indirect and opportunity) of the activities we continue to perform out of inertia rather than economic merit?
3. If we eliminated every activity earning below its cost of capital, how much management attention, working capital and headcount would be released?
4. Which internal functions are structured the way they are because of historical decisions rather than current optimal design?
5. When was the last time we asked “should we still be doing this?” about a significant activity, and acted on the answer?
Closing Implication
The zero-based business review is not a cost-cutting exercise. It is a resource reallocation exercise. It identifies the activities that no longer earn their place and redirects their resources to activities that do.
The discipline is uncomfortable because it questions decisions that were correct when they were made and asks whether they are still correct today. Many will be. Some will not. And the ones that are not, left unquestioned and unreformed, represent the largest single drag on most companies’ performance: the cost of doing what they have always done, long after the reasons for doing it have expired.
