Every department has its own colour, its own priorities, its own pace. Put them all into the same composition without a common framework, and the result is chaos rather than a coherent outcome.
Product wants to protect the roadmap. Sales promises a custom feature to close that one enterprise deal. Customer success wants to stop the churn in cohort three first. Without a shared frame, whoever shouts loudest in the stand-up wins.
Sales says yes to every rush order, planning hunts for drivers who are not there, and finance chases unpaid invoices. Without one shared frame, each department pulls a different trailer and the result turns into noise.
Sales sells fixed prices to hit the quarterly target. Delivery wants a buffer in every sprint. Recruitment chases senior developers, finance chases work in progress nobody has invoiced. Without one frame, each one tugs at your margin.
Sales promises delivery in 26 weeks. Engineering wants to finish the design, purchasing must order long-lead parts before the drawing is frozen, and service wants technicians free for breakdowns. Without one frame, that becomes noise, not results.
The four disciplines force us to make a choice: which ‘wildly important goal’ takes priority when everything is vying for our attention at once.
