Its main purpose is to answer questions:<\/strong><\/p>\n<ul data-start=\"1238\" data-end=\"1338\">\n<li data-start=\"1238\" data-end=\"1282\">\n<p data-start=\"1240\" data-end=\"1282\">What decision will this model help with?<\/p>\n<\/li>\n<li data-start=\"1283\" data-end=\"1304\">\n<p data-start=\"1285\" data-end=\"1304\">Who will read it?<\/p>\n<\/li>\n<li data-start=\"1305\" data-end=\"1338\">\n<p data-start=\"1307\" data-end=\"1338\">How much detail is necessary?<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1340\" data-end=\"1513\">Models for investors are different from internal planning models. Start-up forecasts differ from corporate budgets. Accuracy depends on aligning your model with its purpose.<\/p>\n<blockquote data-start=\"1515\" data-end=\"1642\">\n<p data-start=\"1517\" data-end=\"1642\">Your model isn\u2019t complete if it can\u2019t clearly explain why a decision should be made, no matter how complex the formulas look.<\/p>\n<\/blockquote>\n<h3 data-start=\"1649\" data-end=\"1683\">Make Clear and True Assumptions<\/h3>\n<p data-start=\"1685\" data-end=\"1856\">Models gain or lose trust based on their assumptions. A common mistake is embedding assumptions directly in formulas. This may look professional but reduces clarity.<\/p>\n<p data-start=\"1858\" data-end=\"1877\"><strong data-start=\"1858\" data-end=\"1877\">Best practices:<\/strong><\/p>\n<ul data-start=\"1879\" data-end=\"2012\">\n<li data-start=\"1879\" data-end=\"1920\">\n<p data-start=\"1881\" data-end=\"1920\">Place all assumptions in one location<\/p>\n<\/li>\n<li data-start=\"1921\" data-end=\"1959\">\n<p data-start=\"1923\" data-end=\"1959\">Use plain English and clear labels<\/p>\n<\/li>\n<li data-start=\"1960\" data-end=\"2012\">\n<p data-start=\"1962\" data-end=\"2012\">Base assumptions on logic, data, or common sense<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2014\" data-end=\"2040\"><strong>For example, instead of:<\/strong><\/p>\n<div class=\"contain-inline-size rounded-2xl corner-superellipse\/1.1 relative bg-token-sidebar-surface-primary\">\n<div class=\"overflow-y-auto p-4\" dir=\"ltr\"><code class=\"whitespace-pre!\"><span class=\"hljs-type\">Growth<\/span> <span class=\"hljs-variable\">Rate<\/span> <span class=\"hljs-operator\">=<\/span> <span class=\"hljs-number\">25<\/span>%<br \/>\n<\/code><\/div>\n<\/div>\n<p data-start=\"2069\" data-end=\"2077\"><strong>Write:<\/strong><\/p>\n<div class=\"contain-inline-size rounded-2xl corner-superellipse\/1.1 relative bg-token-sidebar-surface-primary\">\n<div class=\"overflow-y-auto p-4\" dir=\"ltr\"><code class=\"whitespace-pre!\">Growth expected based <span class=\"hljs-keyword\">on<\/span> the company<span class=\"hljs-comment\">'s performance over the last two years and market growth trends.<\/span><br \/>\n<\/code><\/div>\n<\/div>\n<p data-start=\"2188\" data-end=\"2283\">Clear assumptions prepare you for questions, because decision-makers always scrutinize numbers.<\/p>\n<h3 data-start=\"2290\" data-end=\"2319\">Use Real Data for Accuracy<\/h3>\n<p data-start=\"2321\" data-end=\"2387\"><strong>Accurate models rely on real, relevant data, not just guesses:<\/strong><\/p>\n<ul data-start=\"2389\" data-end=\"2483\">\n<li data-start=\"2389\" data-end=\"2409\">\n<p data-start=\"2391\" data-end=\"2409\">Past performance<\/p>\n<\/li>\n<li data-start=\"2410\" data-end=\"2432\">\n<p data-start=\"2412\" data-end=\"2432\">Industry standards<\/p>\n<\/li>\n<li data-start=\"2433\" data-end=\"2463\">\n<p data-start=\"2435\" data-end=\"2463\">Customer behavior patterns<\/p>\n<\/li>\n<li data-start=\"2464\" data-end=\"2483\">\n<p data-start=\"2466\" data-end=\"2483\">Seasonal trends<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2485\" data-end=\"2674\">Example: A sales forecast showing steady monthly growth ignored the reality that half of revenue came during holidays.

Keep calculations simple and explainable.<\/p>\n<p data-start=\"3189\" data-end=\"3202\"><strong>Ask yourself:<\/strong><\/p>\n<ul data-start=\"3204\" data-end=\"3309\">\n<li data-start=\"3204\" data-end=\"3245\">\n<p data-start=\"3206\" data-end=\"3245\">Can someone else maintain this model?<\/p>\n<\/li>\n<li data-start=\"3246\" data-end=\"3271\">\n<p data-start=\"3248\" data-end=\"3271\">Is it easy to update?<\/p>\n<\/li>\n<li data-start=\"3272\" data-end=\"3309\">\n<p data-start=\"3274\" data-end=\"3309\">Can it be explained in a meeting?<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"3311\" data-end=\"3390\">If the answer is no, simplify. Your future self (and your team) will thank you.<\/p>\n<h2 data-start=\"3397\" data-end=\"3441\">Scenario Planning for Real-World Accuracy<\/h2>\n<p data-start=\"3443\" data-end=\"3551\">Markets change, costs fluctuate, and assumptions evolve.
