What does the letters SCS stand for?

Originally the parent Company was called "Security Control Systems", About 10 years ago, we decided that it was too long and the initials were then used, ie, "SCS"
However, although we are reataining the initials "SCS" and there will be a link from the existing SCS website, the new brand is to sit indeperndently from the original.

In view of your comment just a word of advise: A brandname should be short, speakable, a proper noun, composed of no more than four unique characters like Nike or Sony. However, the characters could be repeated like Apple, Coca-Cola, Dell, Lala, Kodak, Costco or Addidas. Successful brands are build on proper brand names, people do not remember acronyms that is not speakable. Acronyms work well but they have to be speakable like Nasa and Abba. As I said, just a word of free advise from someone with 30 years of experience ...

Thank you very much for the advice. We have a large customer database who know of SCS so our logic is based on using that connection but twisting it slightly, hence the emporium and different colours.

A Free Master Lesson in Branding

You are right about the exceptions but it is obvious they did not teach you the reasons in week one or, for that matter, in any other week at art school. Very briefly, the majority of the brands you mentioned are monopolies that have been established decades ago (often state-owned like BP and BBC) when their was no or little competition around, no World Wide Web and no world recession. As a matter of interest, GEs annual revenue exceeds that of most third world countries' annual GDP.

SAP and ATI are proper nouns that are speakable and therefore not relevant to this debate. FCUK is a proper noun that is deliberately miss-spelled for obvious reasons but in our mind (and often aloud), we all pronounce it the correct way as a proper noun.  

Another consumer brand DKNY, was first established around the character of Danna Karan as head designer of the Anne Klein label long before she formalised DKNY as a separate brand with the brand equity created as head designer of the well-known Anne Klein label. Oh, and please note both her name and surname are proper nouns that consist of no more than four unique characters.

Every other brand you mentioned will have its own reason for success but there is not the time or place to go in to all the detail. You would benefit greatly by reading The 22 Immutable Laws of Branding by Luara and Al Ries.

The reality is that none of this is applicable to the SCS Emporium. From their brief it is clear that they do not have a monopoly (let alone a government-backed one at that), the budget and resources of GE or are not a dominant force in a niche market.  

Instead they have a tiny budget, are faced with stiff competition that is greatly intensified by the Internet in the middle of a world-wide recession. Establishing a brand under these circumstances is tough enough, why then put another obstacle in the way like a brandname that is not unique and memorable?

PS I could not help notice "Eagle" in your name Eagle Sign and Design is a proper noun but alas not that unique - when googled it shows over 120 000 000 results. And the description "sign and design"? Do you manufacture signs and design logos in your spare time? Very confusing .

Is your website http://www.scssecure.co.uk/ ?

Yes it is.

Would you be open to alternative name suggestions (at no extra cost of course)?
