Komic,
There is no length restriction for the Module
One Assignment. However, students who simply copy and paste material from web
sites to increase the length of their answer do not get as good a grade as
students who actually integrate the information in an original and intelligent
manner.
gstevens 20:15:18
Good night all and thanks for the feedback on the various industries.
James Scott 20:14:22

Module 2 Discussion Question
Email: anandale@comcast.net
Company Selected: LHS a company I previously worked for that was responsible
for the development of communications billing software applications for use by
wireless telecommunications companies such as Verizon, Cingular and Sprint. The
company had a general product that was used to provide customer management,
call rating and billing for these companies. Some particular customers wanted a
customized version of the software product and hence had the product tailored
to meet their unique specifications.
Specification Type: Production Specification
Type
Example: The contracted customer provided a set of written specifications that
were known as business functionality. Also there were technical (non-functional
specifications that were supplied)
Business Functional Specifications: The following are some examples of the
functional specifications that were requested.
1. Ability to enter names of wireless subscriber customers up to 30 characters
in length.
2. Ability to validate street addresses to provide the most correct street
address for all addresses supplied in the US and Canada
3. Ability report rates in US and Canadian dollars
4. Ability to provide printed reports based on timeframe for call usage for the
following periods: Month To Date, Last Month, Last 3 Months.
5. Ability to change rate plan values and all calls are to be rated at second
interval, not minutes.
6. Ability to generate monthly or on demand bills.
7. All unused call allotments for the current month are to be rolled over to
the next month and added to the monthly allotted.
8. Ability to provide automatic credit to subscribers based on days of service
failures.
9. Ability to accept part and full payments.
With this information additional business rules
were created to ensure that the software product would perform in accordance.
Business Rules were part and parcel of the specification and provided
validation framework. One such rule would be that the system would not allow
the same customer to have more than one account. That is John Doe could not
have more than one account.
Non Functional Business Specifications
1. The system should be able to process over 6,000 calls in 10 minutes or less.
2. The system should be able to bill over 5 milion customers.
3. Bill processing capability and throughput must be 5,000 bills per in 15
minutes or less.
4. Online screen refresh rates should be less than 5 seconds for all customer
transaction screens.
5. Error messages are to be produced indicating system failure.
6. Create 6 levels of security profile with different access rights and
privileges based on supplied roles- 1)Customer service representative, 2)System
Administator, 3)Customer Service Representative Supervisor, 4)Customer Service
Manager, 5) Data Base Administrator 6) Executive Manager
Technical Specifications
1. The system should be able to run on both UNIX, Windows OS operating system.
2. Cached memory of the online applications should be greater than 560K bytes.
3. System should be able to print to any standard printer.
4. System should be able to run on hardware servers from HP, IBM, SUN.
5. Data base should be archived daily and full back up capabilities for
business continuity.

Product Specification:
1. I currently work for Sandia National
Laboratory. We are a contractor to the Department of Energy and Department of
Defense. Our mission is national security.
2. I have chosen to use the product specification. A product specification in
my work environment would be referred to as system requirements. This is a
document in which the customer and us (contractor) would sign off on as an
agreement of what the product will be that we are providing/designing for them.
3. We currently have a number of templates which are used within our program
for all of our projects. One of these templates is our System Requirements
templates includes the following sections:
a. Introduction – includes purpose, scope, definitions, acronyms, references
b. General System Description – includes context, modes and states, major
capabilities, user characteristics, Operational Scenarios, Assumptions and
Dependencies
c. Requirements for System Capabilities, Conditions, and Constraints – includes
Physical Requirements, System Performance Characteristics, System Safety
Requirements, System Security Requirements, Information Management
Requirements, System Operation Requirements, Interface Requirements, Policy and
Regulation Requirements, Quality Assurance Requirements
The main guts of this document are the Requirements for System Capabilities,
Conditions, and Constraints. It is not required that all of the sections of the
template are used. These are only suggestions to give a writer a starting point
with a new project. It is also feasible to have a document that focuses only on
one of the requirements section for example there could be one document which
describes the physical requirements of project. In my work environment we
design vehicles. We have product specifications/requirements documents which
describe the physical characteristics or requirements of the vehicles that we
design. The point of us using and creating these requirements templates is so
that the writer of document takes a moment to think about whether it is
appropriate to include a section of the template in their document as it
applies to their project or to not include the section.

The company I work for is Cardinal Health Snowden- Pencer Product. The company
manufacture, package and distribute various surgical instruments. One of the
product is Desposable Scissor Tip. This product is sold sterile. We are
manufactured and packaged this product in house and send it to Steris for
sterilization.
The component used for the assembly of the
disposable scissor tips are inner and outer blades.
I will discuss the product specifications of
these blades. Product specifications are determined first and have common
components like: product description, required characteristics, handling and
packaging requirements Product specification may contain some additional
elements as applicable.
Product name: Scissor Blade, Curved, Outer, Disposable
The product specifications as well as row
material specifications are provided on the applicable drawing (Drawing scale
4:1).
All dimensions are given in inches. Tolerance
limit:
.xx +/-.005
.xxx +/-.003
ANG +/- 30’
All dimensions were specified on the drawing,
also critical dimensions were defined and specified such as the angle of the
outer and inner curve of the blades and thickness of the blades.
Notes on the drawing specifies the following:
Critical dimensions will be verfied by cut
testing.
Incoming inspection sample size shall be 32 blade sets per lot.
Blades that fail cut test shall be inspected dimensionaly for conformance to
specification.drawing require dimensional inspection if cut test fail.
Cut test blade assemblies must fit through a 5.5
mm cannula. Inner and outer blades must overlap at tip by .015 “min. This
specification will be verified by cut testing

Honda Civic has a very nice aesthetic, a very good safety equipment, more
power, satisfies all driver's needs. The product is able to diagnose and be
fixed with lower costs than the german brand for example. Honda provides a
booklet for drivers showing the user instructions, such as installability and
ease of use of the vehicle. The company provides also the labeling and warning
to drivers. for As far as maintenance is concerned, Honda cars can be fixed in
many mechanic shops and with low cost.

1) Lockheed Martin Aeronautics - This is the
company I have been employed with for 7.5 years. In Marietta, where I work, we
assemble and deliver the F-22 Raptor to the U.S. Air Force.
2) The specification I will discuss is one I deal with and refer to on a daily
basis, the F-22 Aircraft Step and Gap Specification. This spec is considered a
Product Specification in that it defines the allowable tolerances for panel
mismatch and gaps. This specification is developed in a joint effort by
Lockheed Martin design, manufacturing, RCS (Radar Cross Section) engineers and
DCMA (customer).
3) The F-22 Step and Gap spec undergoes periodic changes and is therefore
considered a dynamic document. As mentioned earlier this spec defines how much
of a mismatch and gap (in thousandths) is allowed between panels as they are
final installed on the aircraft prior to Radar Cross Section testing and
coatings. As a QA Engineer in final assembly, I’m constantly referring to this
spec as the aircraft nears rollout to ensure zero panel seams are out of
tolerance on either step or gap. Included in this spec is the following: 1) a
definition and illustration of each type of panel seam on the aircraft, 2) a
detailed description of how to measure each seam, 3) a list of the preferred
measuring tools to use, 4) a list of panel part numbers and names that form the
seam and 5) characteristics - acceptable upper and lower tolerances prior to
and after coatings (although the latter does not apply in final assembly) for
each numbered seam. And as I stated earlier, this specification is updated as
the engineering blueprints are updated, which is on a fairly regular basis. As
the text states on page 26, “Specifications provide checkpoints in
manufacturing that ensure quality of the product”. This certainly is true with
this step and gap spec. All production mechanics, their supervisors, and the QA
inspectors are cognizant of this spec and what the allowable tolerances are
(usually because of my reminding them). Immediately after final panel
installation, the mechanic and inspector will measure the panel step and gap
and reference the spec. This checkpoint is repeated with nearly every panel on
the aircraft.

1. Briefly describe the company you have chosen.
2. Briefly describe the type of specification you will discuss.
3. Use a specific example to help explain the specification, and include as
much detail as possible without exceeding the thirty-minute time limit for your
response.
1. The Company I will discuss is Lockheed Martin division in Manassas, who is a
supplier to the Department of Defense. In this division Lockheed provides
electronic consoles used for command and control of systems on Submarines.
2. We provide a Product specification to Lockheed for an electronic console we
procure to support a sensor system we sell to the Navy. Our specification
describes the environment that the console must survive, the inputs and outputs
of the console and the Graphic User Interface necessary for the operator to
control the sensors.
3. We use a tool called Requirements Traceability Management (RTM) by Syrena to
break the specification down to specific individual requirements. We work with
a Test Integrated Process Team (TEIPT) to determine how each of the
requirements will be verified so we can ensure we completely satisfy the
specification.
There are approximately 2000 requirements which
we must verify and that verification can involve; Inspection, Analysis,
Demonstration or Test. We assign a project unique identification number to each
requirement. As we work through the requirements, we find that initial concepts
of how requirements would be verified are not always practical, so the TEIPT
adjudicates any new process proposed by members.
We develop a table in RTM called a System
Requirements Verification Matrix (SRVM) that we use to allocate the
requirements to individual Hardware or Software Configuration Items. We
identify individual test procedures, which we assign to each requirement.
In some cases a test procedure will cover many
requirements, in one case about 700 requirements. We require that the procedure
contain a requirements table to correlate individual steps in the procedure to
the requirements that they verify. In this manner we can ensure each requirement
is verified by checking off each requirement that we verify in the SRVM Table
as we conduct the verification.

The company I chose to discuss manufactures
heavy industrial equipment for the scrap and recycling industry. Their main
customers are commercial scrap yards and recycling centers. The particular
application I am referring to is the customer who recycles old automobiles for
scrap metal. These customers use a very large shredding mill that grind
automobiles into small pieces, which are then separated into ferrous,
non-ferrous, etc. The ferrous metal is sold, usually to China for use in making
steel.
Product specifications dictate 2 important
aspects. First, the shredding process should yield ferrous pieces that are as
small as possible. Larger pieces require more fuel to melt therefore it is very
important to the customer to have the pieces as small as possible. Given
current fuel prices, this is the most important specification. An ideal piece of
ferrous shred would be no larger that 2” x 2”.
Secondly, the scrap should be clean. As much of the dirt, plastics, debris
should be removed to reduce the amount of cleaning required. Although this
parameter is a more subjective specification, customers will request this in
their product specifications. This specification is addressed with adequate
down-line systems requiring magnets, eddy-current and manual pickers.
The scrap industry is a $30 Billion industry and
customers want as much product as they can get with minimal waste.

The company chosen is Third Wave Technologies. This company is in the molecular
diagnostics industry. The products offered allow laboratories to test patient
samples to identify genetic predispositions to various diseases. For instance,
the company has a product that when mixed with a patient’s DNA, it can tell a
physician whether a certain drug will cause an adverse reaction based on the
patient’s genetic makeup. Third wave technologies is regulated by the FDA.
The specification chosen is the Quality
Management Specifications. These institute the framework of procedures,
controls and methods required to make a product. Quality management
specifications can be modeled against ISO standards, the Malcolm Baldrige National
Quality Award, etc.
Recently, the company decided to outsource the
manufacturing of one of its products. While examining different candidates for
this task, the company used several supplier surveys to begin assessment of
potential external facilities. One of the major requirements for this product
is that is manufactured under Good Manufacturing Practices (GMP). We found a
suitable candidate that had the systems in place to meet this specification and
we drafted a supplier agreement. In this document, we specified that although
we did not required them to be registered as a GMP facility, we required that
our products were manufactured under a quality system modeled against GMPs.
After an on-site audit of this supplier we knew that they would not have a
problem agreeing to this specification and they signed the agreement.

1. Process Specification
The company I will reference to is a tier one
automotive supplier (Transmission Supplier to the Big-Three). I worked there as
a quality technician. This company is a fairly large plant (200-250 employees).
They supplied a total of 12 different models of transmissions. Being a quality
technician I was directly affected by process specification, because I had to
insure we were producing the product to specification.
I was a quality technician to the machining
department. All our process specifications were pulled directly from the
supplied blue print. These prints were trickled down to various approval
processes before the product was produced as full scale production. For
example: a Pre-Production Approval Process (PPAP) was completed with an initial
print to insure the product could be made at the desired specifications. A
capability study would be completed at the time of the PPAP. This capability
study would use the process specifications as inputs to calculate Cpk & Ppk
indexes. On all critical specifications the customer would require a Ppk of
1.67 and on non critical specifications a Cpk of 1.67 was required. If these
targets were not meet the engineering group and the customer would meet to see
if the process specifications were feasible. Most of these process
specifications were dimensional. For example: transmission housing would need
to be a certain length to insure all the components associated with the housing
would fit properly. This length would be measured on a Coordinate Measuring
Machine (CMM) to check the length of the housing was correct to the process
specification.

Product specifications as described by Bossert,
defines what is required for a product to perform as expected by the consumer.
The company that I work for (HED) produces hydro electronic devices. The engineering
department provides the production department with a drawing, a bill of
material, and testing procedures specific to that part. At times we find this
“manufacturing packet” could use more detail to help prevent misinterpretations
or potential nonconformities. If this addition or clarification could affect
the form, fit, or function of the part, production initiates an ECR
(engineering change request) for an update to the drawing. For example, if the
drawing does not spell out the orientation of a component it should not be
assumed that everyone will interpret it the same. If it does not affect f/f/f,
then production initiates a quality specification sheet. This is a tool that
the Production Supervisor controls and uses to communicate such information,
including alerts to quality issues that have arisen.

Briefly describe the company you have chosen.
I have chosen to discuss GE Contractual
Services. GE Contractual Services provides long-term service agreements for
planned and unplanned maintenance activities on the GE provided equipment. This
is a $3B + company and provides approximately 4% of all General Electrics
revenues.
Briefly describe the type of specification you
will discuss.
I have chosen to address process specifications.
GE Contractual Services (GECS) does not actually create a product. It is
primarily a provider for a financial solution to GE OEM business consumers. It
provides equipment guarantees on purchased equipment and accomplishes this via
guaranteed maintenance activities. GECS has a proprietary application called
“outage Excellence”. This application is an automated checklist that has
required steps of an outage planning exercise prescribed in a portal for the
contract manager. Outage Excellence schedules mandatory maintenance planning
reviews for the user and automatically notifies required parties to ensure
completion and compliance for each of the mandatory tasks at pre-defined
intervals as the outage approaches. For example, there are mandatory tasks to
be performed at the 18-month, 1-month, 8-month, 6-month, 3-month and 1-month
stages of the planning process. As tasks are completed, they are marked
“complete” within the application by role of attendee. These activities are
reviewed with the Customer to ensure satisfaction. The application is slightly
older than 2 years and has gained resounded credit by our Customers.
Use a specific example to help explain the
specification, and include as much detail as possible without exceeding the
thirty-minute time limit for your response.
The process tracks “Variance to Want” time spans
for contract compliance. If the variances to the customer want (VTW) date are
approaching or excessive, it escalates the compliance task to the responsible
parties direct manager. As well, for each section of compliance, it captures
metrics surrounding the process such as “on-time delivery” of parts and
services and discrete data around timely completion of area such as
Environmental, Health and Safety, Quality Checks and procedure development. The
application also records metrics surrounding the completion of mandatory tasks
during and post-outage. This application allows us to understand where our
business needs improvement to ensure Customer satisfaction and contract
compliance. This is important because we can incur liquidated damages du to
failure to comply.

The specification I would choose is product specification and the company that
I am familiar with is Honda as I own a car make Honda. The company has a set of
product specifications that provide checkpoints in manufacturing to ensure a
high quality of the vehicle. Honda Civic has a set of product specifications
since to drivers it is reliable, can work for years with less mechnaical
problems.
