Book of the Week: Developing Business Scorecard Metrics + Smoot’s Ear

What are three char­ac­ter­is­tics of good busi­ness score­card met­rics? In con­struct­ing an effec­tive met­ric, the designer needs to look at three fac­tors before set­ting tar­gets: 1) Sim­plic­ity: Is the met­ric sim­ple and easy to under­stand? Is there a direct rela­tion­ship between action and result? For exam­ple, say this is a retailer who oper­ates in multiple […]

Book of the Week: History of Topographical Maps

The His­tory of Topo­graph­i­cal Maps by P D A Har­vey is a schol­arly sur­vey of how the topo­graph­i­cal map was devel­oped, begin­ning in clas­si­cal antiq­uity through medieval times. I saw it in a local used book­shop in Red­mond near my house. Car­tog­ra­phy has always fas­ci­nated me, esoe­cially the­matic maps that visu­al­ize data. The book looks […]

New Series for 2013: Classification as a Tool of Thought

Clas­si­fi­ca­tion and tax­on­omy has always inter­ested me and this year I’d like to exam­ine how clas­si­fi­ca­tion and group­ing impacts analy­sis. Group­ing data in var­i­ous tax­onomies can have a vari­ety of results: dis­as­ter, if the cat­e­go­riza­tion scheme hides or sug­gests arbi­trary things when there is no nec­es­sary con­nec­tion or if the con­nec­tion is biased, or deeply […]

New Tool: Graph Commons

Graph Com­mons is a new tool that I’m play­ing with. Sim­i­lar to sites like Many Eyes, you can upload data, cre­ate graphs, and share with other com­mu­nity mem­bers. The tool focuses on net­work dia­grams. Here’s an exam­ple of how a tax­on­omy for archi­tec­tural types based on the book Isms: Under­stand­ing Archi­tec­ture. I will try to […]

Start-​Cap — RFID enabled bottle cap

Start-​cap is a bot­tle­cap with embed­ded RFID capa­bil­ity. It’s still exper­i­men­tal, but some ideas its cre­ators have explored are “flash-​mob” like actions. The cap can enable a glit­ter can­non in a bar or turn on a spot­light in a bar. It will be inter­est­ing to see what hap­pens when the indi­vid­ual caps inter­act with each […]

Classifying Sporks, Spifes, and Knorks…

How do you clas­sify eat­ing uten­sils and odd hybrids like sporks (spoon-​fork), spifes (spoon-​knife), knorks (knife-​fork), sporfs and splayds(spoon-fork-knife)? One way is to clas­sify by uten­sil and com­bi­na­tion of uten­sils: Fork: semi to solid foods Spoon: liq­uids to semi-​solid foods Knife — solid foods (for prepa­ra­tion) Spork: Fork-​Spoon — liq­uids to solid foods Knork: Fork-​knife– […]
