DCIG Buyer's Guide FAQ
Whenever DCIG publishes a new DCIG Buyer's Guide it generates a number of questions. This FAQ seeks to provide answers to those questions and explain why we do the things we do--and why we don't do some things that initially seem like a good idea.
The questions that come to us typically are grouped around several themes:
- Why did/didn't DCIG include data about feature xyz?
- Why did/didn't DCIG include product xyz?
- Why did DCIG create this Buyer's Guide?
- Do the DCIG Buyer's Guides truly provide an independent viewpoint?
Where DCIG Analysts can anticipate specific questions, we provide answers in the analysis portion of each DCIG Buyer's Guide. Within each Buyer's Guide, we also very clearly describe the independent process by which we establish evaluation criteria, select products for inclusion, score the products, and communicate with vendors. If you are interested in seeing the detailed answers that relate to a particular Buyer's Guide, please download the relevant DCIG Buyer's Guide.
DCIG seeks to include only features that can be objectively and authoritatively analyzed. The features most frequently asked about are effective storage capacity after deduplication and other data compression techniques have been applied, and IOPS-related performance numbers. Indeed, we have debated their inclusion but ultimately concluded that these data elements could not be established objectively or would vary significantly based on site-specific implementation decisions and data center infrastructure factors. DCIG's president has written the definitive DCIG viewpoint on the performance question in "A 7 Part Answer to the Performance Question".
The inclusion of a product in the Buyer's Guide generally comes down to two tests. The first test is whether or not the product meets the technical criteria for inclusion. The technical criteria set the primary boundaries. Our intent is for these boundaries to reflect criteria that are relevant to a particular kind of buying decision.
The second test is the availability of sufficient information for DCIG to do a meaningful evaluation of the product. DCIG makes a good faith effort to reach out and obtain information from as many vendors as possible by providing surveys to them for them to complete. DCIG analysts also fill out surveys for vendors based on information available from their web sites and other reliable sources. Some products that might meet the technical criteria for inclusion may still be excluded because of insufficient data.
DCIG creates Buyer's Guides in order to help end users accelerate the product research and selection process--driving cost out of the research process while simultaneously increasing confidence in the results. DCIG analysts choose a topic for a Buyer's Guide where marketplace confusion exists. Marketplace confusion results from numerous vendors and products in the marketplace combined with a lack of readily available comparative data. DCIG seeks to provide this missing comparative data along with informed analysis.
DCIG accomplishes this goal of faster and better-informed purchasing decisions by providing an informed, third party evaluation of products that scores their features from an end user viewpoint. DCIG's product rankings dashboards and standardized one-page data sheets enable "at-a-glance" comparisons that help organizations to quickly get to a short list of products that may meet their requirements. The result is a 50-90 page Buyer's Guide that can be used by business technology leaders who evaluate, recommend and purchase data center infrastructure products.
Q4: If this is an independent buyer's guide, why does the download link take me to a vendor's web site?
After initial completion, the Buyer's Guide is then offered for license to the vendor with the overall "Best-in-Class" product. The licensee subsequently provides end users with a time-saving resource at no cost to the end user in exchange for the end user's contact information.
Prior to the completion of the guide, there is NO sponsorship of Buyer's Guides. The Buyer's Guide is created knowing there will be a winner, but we "let the chips fall where they may" on the results.
DCIG has an 8-Step process we use to score and rank products that is fully described in each buyer's guide. In summary, the 8-Step Process Used to Score and Rank Products is:
- DCIG lists out all of the features available on all of the products.
- DCIG establishes which features should be included in the Buyer's Guide and which ones should not.
- Each included feature is assigned a scoring weight.
- The features are grouped into general categories.
- A survey is sent to each vendor that asks about all of the features that will be scored in the Buyer's Guide. If a vendor chooses not to fill out a survey, DCIG analysts attempt to collect the data from vendor web sites and other reliable data sources.
- All vendors are given the opportunity to review their unscored/unranked data sheets before the final scores and rankings are determined.
- All of the features are scored based upon the data that was gathered.
- The vendors are ranked using standard ranking techniques.
