Professional Experience
Solutions beyond standard job assignment –Responsible for
numerous Lucent-wide solutions, both on personal initiative and at the
request of external organizations
- Solectron CP-Level Forecast – directly sources circuit pack
demand on Solectron, avoiding erroneously inflating demand via
higher-level product structures. $22M+ in reduced over-forecast.
- Available to Promise (ATP) Tool – a web-based solution
providing order desks with visibility to global inventory and scheduled
receipts. No other global visibility and promising tool exists
within Lucent.
- Surplus Active OIs identification tool -
provides visibility to
surplus availability of non-X orderable items that have shown recent
demand. Currently providing visibility to over $74M in potential
sales.
- Celestica and Solectron SuperBOM tools – provide a means to
manage component level buffer inventory at the EMS for customer delivery
assurance.
- OEM Quote Impact Tool – a web-based tool that explodes quote
demand and sources it to OEMs to provide a view of what’s in the
funnel. It has been adopted as part of the SMG Tools utilities.
- Phase Out Tracking Tool - the global repository of phase out,
last time buy, and X-free activity providing visibility to $5M of
“over-target” inventory
- WES Advanced Shipment Notification (ASN) Quick Win - automates
the transmission of data to WES for a reported savings of $1.4M
- WES Compliance Metric Quick Wins – provides a web-based view
of previously nonexistent WES performance metrics
- Basic Network Elements (BNEs) Tool – automates the generation
of simplified product units – 80% interval reductions, 10x turns, and
millions in SC savings realized.
- Optimal profiles – spreads GSP forecast based upon historic
demand, aligning orders with forecast, reducing costs associated with
early/late builds by 30%.
- Commonality Metric – provides a measure of commonality and
postponability at the item and product levels. Ownership
transferred to Bell Labs Ireland.
- Pegging Tool - optimally builds parent items given inventory,
both on hand and future receipts
- Critical Materials Management (CMM) Tool - provides an
otherwise absent confirmation that downstream suppliers are receiving the
forecast as intended
Global Supply Planning (GSP) (2002-Present) – GSP Solution
Architect
- Personally prototyped the GSP solution, made it work and proved that
it worked via daily validations
- Consistently provides innovative solutions to difficult problems such
as Tier 1 data integration
- Team lead for the SSG, ACC, and INS integrations
- Solely responsible for GSP BR2 design, implementation, testing,
integration
- Solution for CG-level reporting when the core GSP solution wasn't
capable due to hardware constraints
- Consistently provides production data when standard solutions are
incapable, e.g. forecast netting
i2 SCP Implementation (2001-2002) – Responsible for integrating
the SCP and DP solutions for WNG. Responsibilities included
- the design and support of the Supply Chain Cockpit,
- the design of all software to build the i2 model for BR2 including
Forecast Netting, Master Planning, and Forecast Sourcing,
- the design of all software to control the Forecast Netting, Master
Planning, and Forecast Sourcing automated workflows,
- the design of all software to interface the Supply Chain Cockpit with
external systems,
- and the design and support of SCCPlan to provide commits for Mt Olive
until Webplan was deployed.
Network Fault Management (NFM) software development
(2000-2001) – Subsequent to receiving a PhD, led all Oracle
development and support for NFM. Accomplishments include
- a feasibility study to justify moving the Topology Database from
shared memory to Oracle,
- the design and development of tools to load, maintain, and query the
Topology Database for R11,
- TIM12.0 upgrade software to support replication,
- the development of software to support backups on the Common
Database,
- and the prototyping of R12+ software changes.
Consulting and Research (1996-2000) – While earning a Ph.D.,
- developed software for the Lucent Network Fault Management (NFM)
product,
- led Lucent project management teams, developed software, performed
database administration, and performed process engineering for S&NP,
- converted Lucent Surface Mount placement machine software to operate
from an Oracle database for WNG (Fuji XCME software support),
- and automated the generation of placement programs for the
through-hole machines in the Lucent Operations Systems/Switching Systems
shop.
- As a Research Assistant at Ohio State, performed comparison of neural
networks and linear regression in response surface analysis of small data
sets. Research papers are pending.
- In a dissertation, entitled Queuing Network Construction Using
Artificial Neural Networks, an approximate solution method is proposed
for the analysis of general queuing networks. The queuing
network is decomposed and each node is modeled individually using an
artificial neural network (ANN) trained via simulation to act as a
“generic” queuing node. The ANN accepts interarrival and service
distributions in the form of histograms and generates a departure
distribution and a performance measure. The performance measure
approximations are compared to analytic methods and to a “correct”
simulated result. The method is demonstrated on both infinite and
finite queuing systems.
Surface Mount Technology process development (1994-1996) –
Responsible for networking the Fuji placement machines, providing tools
to automatically validate the placement programs, automatically optimize
placement programs, and automatically optimize setups across groups of
codes. Developed a program to extract placement data from the
Fuji machines, permitting data-driven quality initiatives. Some of
the software was employed by other Lucent locations, including Oklahoma
City.
Developed software to automate/facilitate the operation, engineering, and
management of the surface mount processes. Mark was personally
responsible for cost savings in excess of $4M. Responsibilities included
quality improvement, design for manufacture, and the introduction of new
products. Leadership roles in Engineering and Process Management
teams.
1B Processor Circuit Pack Assembly (1992-1994) – Personally
responsible for specifying, procuring, and proving in all circuit pack
assembly processes and equipment used in the manufacture of the 1B
Processor. Full responsibility for the design, procurement, and prove-in
of all circuit pack assembly processes for the 1B Processor. Coordinated
the efforts of all assembly engineers on the 1B Processor project.
FLEXLINE/JIT methodology (1986-1992) – Systems engineer on the
development team that implemented the FLEXLINE manufacturing line.
Involved in the reengineering of the Operations Systems manufacturing
operations to create a high velocity, flexible manufacturing environment.
Specific responsibilities included the queuing and simulation analysis of
the proposed systems, the procurement and installation of facilities, the
reengineering of existing processes, documentation, training, and
ultimately the engineering support of the completed operations.
Involved in $3M of cost reduction.
