The material addresses key challenges driven by requirement volatility and the intangible nature of software scope, contrasting these with practical measurement using Function Point Analysis and IFPUG standards. It then details the SiSE workflow, including action-verb decomposition, sizing, uncertainty range review, historical growth adjustment, and validation.

Currently, there are fewer than 1,100 certified analysts worldwide and under 100 in the US.  \n3  \nSimplified Software Estimation (SiSE) Approach to Software Sizing  \n1  Action Verbs List  \nCreate a list of action verbs to decompose into weighted components based on the SFP  \nmethod.  \n 2  Estimate Program Size  \nMatch action verbs from software requirements to their weighted SFP values to estimate  \nprogram size.  \n3  Uncertainty Review  \nReview for uncertainties in sizing and provide a range with justification for each  \nrequirement.  \n4  Sum and Adjust  \nSum the values and apply historical growth factors to the estimates.  \n5  Validate Estimates  \nReview the final size estimate for consistency and compare with prior estimates as a  \ncross-check.  \n4  \nSiSE Example: AlertHub  \nAlertHub: Your Personalized Notification Platform  \n• In a bustling city, where every moment counts, a team of tech enthusiast created AlertHub, a revolutionary software product designed to keep citizens informed and empowered.  \n5  \nSiSE Example: AlertHub  \nTailored to Your N eeds  \nA lertH ub allows users tocusto m ize their notificatio np references, ensuring they alerts that are truly relevant to their daily lives .
