From quadrant to funding test
A quadrant is only a funding hypothesis until the market, cash mechanism, strategic unit, owner, and review trigger are visible.
Reference & Evidence
Source: Author's matrix-to-funding framework grounded in Henderson (1970), Robinson (1986), and Nippa, Pidun and Rubner (2011). All rows are synthetic decision hypotheses and do not describe a company or market.
Each line is a claim from the register this journal publishes against, resolved from the register at build time.
- B Henderson's own sentence: "The portfolio composition is a function of the balance between cash flows" henderson-1970-product-portfolio ·
HEN70-C1 - B "High growth products require cash inputs to grow. Low growth products should generate excess cash" henderson-1970-product-portfolio ·
HEN70-C2 - B The four positions are named by their coordinates: "Products with high market share and slow growth are" cash cows, "Products with low market share and slow growth are" pets, "Low market share, high growth products are the" question marks, and "The high share, high growth product is the" star henderson-1970-product-portfolio ·
HEN70-C3 - B The balanced portfolio has "stars whose high share and high growth assure the future", "cash cows that supply funds for that future growth" and "question marks to be converted into stars with the added funds", while "Pets are not necessary. They are evidence of fail"ure to lead or to exit henderson-1970-product-portfolio ·
HEN70-C4 - A CPM comprises "entry into new businesses, allocation of scarce resources to different business units, and liquidation of value-destroying divisions" nippa-pidun-rubner-2011-corporate-portfolio-management ·
NPR11-C1 - A The coordinates are proxies, and the review says so: "market growth (as proxy for cash demand) and relative market share (as proxy for cash generation via an experience curve effect) constituted the basic dimensions" of the concept nippa-pidun-rubner-2011-corporate-portfolio-management ·
NPR11-C2 - A Corporate portfolio management is the process and not the display: it is the thing "which should not be limited to simple matrices or other instruments for managing the corporate portfolio" nippa-pidun-rubner-2011-corporate-portfolio-management ·
NPR11-C3 - A The review separates the tool from the practice: "Criticizing strategic management tools such as CPM matrices because of oversimplification requires a clear distinction between instrumental simplification and misleading, logical, or methodological oversimplification" nippa-pidun-rubner-2011-corporate-portfolio-management ·
NPR11-C4 - A The trade-off is stated as a design constraint on any such instrument: methods "need to consider the inherent uncertainty, dynamism, and complexity of the strategic setting" nippa-pidun-rubner-2011-corporate-portfolio-management ·
NPR11-C5 - B The count IS in the paper, twice: "There are 13 mitigating factors that must be borne in mind before the cash flow characteristics of the strategic menagerie can be applied slavishly", and the abstract's "Thirteen caveats ranging from the breakdown of the implicit correlations between cash flows and market share and market growth rate through motivational and political problems must condition a competent analysis". Corrected 2026-09-07: this row said the paper enumerates no thirteen, which is contradicted by its own abstract robinson-1986-growth-share-matrix-caveats ·
ROB86-C1 - B The share axis may not carry cash flow at all: "relative market share may not be correlated with cash flow", and "The relationship between market share and cash flow may" fail when other economics dominate robinson-1986-growth-share-matrix-caveats ·
ROB86-C2 - B The growth axis carries the same warning: "market growth rate may not be strongly negatively correlat"ed with cash flow, because "High entry barriers may exist. Margins may be sustainable and large enough to produce" positive cash flow while growing robinson-1986-growth-share-matrix-caveats ·
ROB86-C3 - B Market definition is a positioning error, not a rounding error: it can rest on "the incorrect assessment of market boundaries based on faulty geographic, demographic, psychographic, behavioural, competitor, and other variables", and "The level of market segmentation affects the positioning" robinson-1986-growth-share-matrix-caveats ·
ROB86-C4 - B "High rates of inflation have a serious effect on the measure"ment of market growth and on the cash-flow characteristics of any business robinson-1986-growth-share-matrix-caveats ·
ROB86-C5 - B Implementation is organisational, and transfer pricing is the sharpest case: "It is possible to show an accounting profit wherever it is most desirable dependent on the manipulation of transfer prices" robinson-1986-growth-share-matrix-caveats ·
