sample work

Steve McCoy has always been a strong believer that effective management and leadership in highly technical disciplines requires continuous involvement with detailed understanding of the technologies.  For him, that has included maintaining competencies in programming languages and techniques as well as networking protocols and configurations.  In typical work situations, he has worked closely with his team members to "lead by example", mixing the providing of guidance to others as well as providing low-level engineering tasks himself.  He remains very comfortable delivering both types of technical work.  In addition, his extensive background in understanding the relationship between the technology and the business have resulted in him providing a majority of the data reduction and analysis of financial models in lines of business that he has worked in.  He is a strong believer that understanding discrete "units of work" and their costs is critical to managing any business.


 

The following items represent a few samples of McCoy's more "engineering"  oriented activities.  While much of this type of work product was and is "owned" by his previous employers, he often has created tools and utility resources for use across organizations (including for clients) that are non-specific to the businesses but demonstrate some of the skills required to perform necessary technical tasks.  Below are a very few examples that may be useful to readers as well.     Click on any of the document titles to access them.

Simple VoIP Bandwidth Calculator -   This "Voice over IP bandwidth calculator" allows you to enter a number representing a required number of simultaneous calls (the key factor in calculating VoIP) and provides the required network bandwidth required for that solution.  The spreadsheet then works with sample tables from a couple network providers (in this case, AT&T and Sprint) and provides an estimate of what the costs would be to implement such a configuration.  These tables are purely samples and could be easily be replaced by the information that would be specific to any particular business.  This tool accomplishes several common telecommunications engineering functions in one simple tool.  These examples are not necessarily representative of what costs would be in your particular environment.  This example is a Microsoft Excel file using VBA.  If you need a non-Microsoft version please drop me an email and I will be glad to send you another version of the information.

TDM versus VoIP Modeling - Contrary to what much media hype might have folks believe, Voice over IP is not always more cost effective in delivering phone calls than classical TDM (time division multiplex) circuit configurations.  As part of an overall network strategy VoIP may have other advantages in your network than just unique line costs, but it's important to understand discrete components.  This particular model combines some more simple "per minute" charges of TDM and the "bandwidth" cost of VoIP to draw a comparison in how an interactive environment or call center might be affected by differences in Call Volume, Peak Call Rates, Average Call Rates, and Average Call Length to create estimates of how much TDM and two different VoIP compression models might affect a business cost.  These underlying data is purely sample and could be easily be replaced by the information that would be specific to any particular business.  This tool accomplishes several common telecommunications engineering functions in one simple tool.  These examples are not necessarily representative of what costs would be in your particular environment.  This example is a Microsoft Excel file using VBA.  If you need a non-Microsoft version please drop me an email and I will be glad to send you another version of the information.

Provider1 to CustomerX Functional Business Requirements - This document was authored by McCoy as a "Functional Business Requirements" assesment of a complex set of implementation challenges for a major client.  The company names have been expunged, but the document contains network drawings, narrative design response, SIP signaling sequence diagrams, and other analysis material that is representative of McCoy's ability to provide both technical and business saavy information when required.  It represents a complex configuration of interactive voice response systems, multiple contact centers, and data communications access.  A primary objective was to convert the contact centers to VoIP operations but maintain interface capabilities with Cisco's Intelligent Call Management(ICM) service product.  Most call centers operated Avaya ACD systems, but others were also in play at 3rd party contact centers.  Because of the client's technology plans, this solution also included creating an ability to combine standard VoIP/SIP signaling with more classic Cisco proprietary solutions.  McCoy has spent many years helping clients implement new standards, but also migration strategies that allow the coexistence of standards-based and custom solutions together.
