eTutorial Brief: Unified Modeling Language (UML)

This eTutorial Brief explains the Unified Modeling Language (UML), a standardized general-purpose modeling language in the field of object-oriented software engineering. The standard is managed, and was created, by the Object Management Group.
UML includes a set of graphic notation techniques to create visual models of object-oriented software-intensive systems. The tutorial uses The Visible Analyst to specify, visualize, modify, construct and document the activities of an example application. Techniques from data modeling (entity relationship diagrams), business modeling (work flows), object modeling, and component modeling are illustrated throughout the tutorial.


Depth of Modeling

Have you been asked to do a process model and you just don’t know the amount of detail that you need to do a successful model? The level of granularity that you have in your process model will determine how successful this will be.

Process models ought to form part of a bigger & better picture of your organisation via a connected process architecture of relationships & dependencies.

Aswath Damodaran: "Valuation: Four Lessons to Take Away" | Talks at Google

The tools and practice of valuation is intimidating to most laymen, who assume that they do not have the skills and the capability to value companies. In this talk, I propose to lay out four simple propositions about valuation. The first is that valuation is not an extension of accounting, insofar as it is not about recording the past but forecasting the future. The second is that valuation is not just modeling, where people put numbers into Excel spreadsheets and pump out values. A good valuation requires a narrative that binds the numbers together. The third is that valuing an asset or business is very different from pricing that asset or business, a difference that is often blurred in practice. The fourth is that luck plays a disproportionate role in whether you make money off your valuations. Put differently, you can do everything right and still walk away with nothing or worse at the end.

About the Author
I view myself, first and foremost, as a teacher. I do teach valuation and corporate finance not only to MBAs at Stern but to anyone who will listen (on iTunes U, online and on YouTube). I love to write books, teaching material and blog posts. After 30 years of teaching finance, I still find it fascinating as an interplay of economics, psychology and number crunching.
