Wikipedia:Articles for deletion/Mayo-Smith's Pyramid

I have proposed this article for deletion according to WP:NN. This article fails to meet the criteria set forth as follows:

Significant Coverage: Single source provided covers only the topic of the article as an illustration.
Reliable: The single source provided is clearly not reliable as it is from an information technology magazine, which has no claim to editorial prowess in the field of project management.
Sources: There is only one source provided which refers to this diagram, and not even by the title given in this article.
Independent of the subject: The author of the only provided source is the one for which the eponymous diagram is named and is therefore completely subjective. --DCrazy talk/contrib 17:05, 17 July 2007 (UTC)[reply]

Speedy delete as spam - I've tagged it as such. ɑʀкʏɑɴ 17:23, 17 July 2007 (UTC)[reply]

Not speedy, since it's not blatant advertising for the magazine cited. Beyond that, I believe I've seen this diagram used in recent Agile process books, but I haven't seen it referred to with this name. I'll check for external sources. Tlesher 17:34, 17 July 2007 (UTC)[reply]

I still think it's spam - not for the magazine, but for Mr. Mayo-Smith and his methods. ɑʀкʏɑɴ 18:03, 17 July 2007 (UTC)[reply]
