This asymmetry better matches technology markets where early adoption is driven by innovators (fast) but late-stage saturation is drawn out by laggards. + +**Source:** +- [EE Times - Gompertz for semiconductor prediction](https://www.eetimes.com/predicting-semiconductor-industry-growth-drop-the-crystal-ball-and-use-the-gompertz-curve/) +- [Semiengineering - Gompertz model](https://semiengineering.com/mathematic-model-helps-predict-markets-that-will-drive-semiconductor-growth/) +- [FasterCapital - Business growth](https://fastercapital.com/content/Gompertz-Curve--Modeling-Mastery--Using-the-Gompertz-Curve-to-Forecast-Business-Growth.html) + +### 1.5 Weibull Distribution for Lifecycle Curves + +The Weibull distribution provides a **flexible framework** for modeling both growth and decline phases with varying shapes. + +**Lifecycle formulation:** + +``` +f(t) = (β/η) * (t/η)^(β-1) * exp(-(t/η)^β) +``` + +Where: +- `β` = shape parameter (β < 1: decreasing failure/decline rate, β > 1: increasing) +- `η` = scale parameter (characteristic life) + +A 2019 paper proposes a **two-step Weibull distribution** with four parameters for modeling bimodal product lifecycle diffusion curves — fitting both the rise and fall of product sales. + +**Source:** "Using Weibull Distribution for Modeling Bimodal Diffusion Curves: A Naive Framework to Study Product Life Cycle."
