Decision Matrix
The document discusses using a decision matrix to objectively select from a range of options based on weighted criteria. A decision matrix is a table that lists criteria down the left side, options across the top, and scores for each option against each criteria in the cells. It involves identifying criteria, weighting their importance, rating options against each criteria, and calculating a total score for each option by multiplying the ratings by the weights. The example decision matrix shows choosing a holiday destination based on entertainment, culture, travel, and accommodation criteria.
decision table training session
This document provides information about decision tables, including:
- Decision tables lay out all possible business decision situations in a tabular format.
- They list causes and effects, with each column representing a unique combination of causes and expected effects.
- The purpose is to structure logic and test combinations in a systematic way.

Decision Table Based Testing
This power-point presentation covers DECISION TABLE BASED TESTING under software testing with theory and example.
Decision table
Decision tables provide a compact way to represent complex business logic by listing all possible combinations of conditions and their associated actions or effects. They help ensure all scenarios are considered and can prevent errors and inconsistencies. For example, a decision table could show that an ATM withdrawal is granted if the requested amount is less than or equal to the customer's account balance or if the customer has been granted credit to cover the amount. The table would list the conditions, such as withdrawal amount and available credit, and the resulting action of approving or denying the withdrawal.
Decision making and problem solving
Decision making involves choosing between alternatives and reaching a judgment or opinion. It is a cognitive process that includes considering options and making a choice. The decision making process involves defining the problem, analyzing it, generating possible solutions, analyzing the solutions, selecting the best option, and planning the next steps. Problem solving is related and involves working through the details of an issue to find a resolution. It follows a similar process of identifying issues, understanding interests, listing options, evaluating options, selecting an option, documenting agreements, and planning for contingencies. The key elements of decision making include understanding who is affected by the problem, setting the agenda, considering rationales, determining the scope and seriousness, using technical aids, implementing the outcome.

The document discusses the value of reducing scrap in production processes. The author was assigned a project to reduce scrap at Andersen Windows. They discovered that over $25,000 worth of material was being discarded as scrap in just four months from one production line. By implementing a system to reuse leftover material pieces, they were able to cut scrap costs nearly in half. The main lesson is that easy solutions may exist to significantly reduce scrap and save both money and resources, if production processes are reexamined with an eye toward scrap reduction.

Eco inventor drawings
Thomas Edison was a prolific inventor who created and patented many inventions including the phonograph and the motion picture camera. He kept meticulous records of all his ideas and experiments through detailed technical drawings and notebooks. These drawings and records provide a glimpse into Edison's innovative process and how he developed many world-changing technologies through experimentation and persistence.
Design brief cord flex.doc
The client, Product Safety Consulting Inc., needs designers to create an improved universal clamp to securely hold various products during machine testing. The existing clamp is unreliable and expensive as it requires constant human monitoring. The new clamp must fit existing fixtures, accommodate different sized products, be portable, and allow attached cords to rotate freely.
Cord flex inventor drawings
The Cord flex Inventor Drawings document contains design drawings for a new cord management device. The drawings show the device has a flexible arm that can wrap around a cord to keep it organized and a base that attaches to a surface. Key dimensions and notes are included to guide manufacturing.
The cord flex’s new clamp
The document discusses issues with the current clamp used in product testing at Cord Flex, which often slides off or requires new custom clamps for different product angles. It proposes a new adjustable clamp that would hold products securely from all four sides using bolts and nuts, saving time and money over the current clamp that needs redesigning for each new product. Drawings of the new clamp prototype were created in Autodesk Inventor.

Test
The document describes 10 tests of different floatable foundation designs. The first 4 tests involved a palette alone, bottles alone, bottles with 3 pounds, and a palette with bottles. Tests 5-9 added increasing amounts of weight from 10 to 72 pounds to a palette with bottles, and all stayed afloat. Test 10 with a palette, bottles and 100 pounds sank under water.
Design brief
The design brief is for a floating foundation made of recyclable materials to provide housing for people in the Republic of South Africa prone to flooding. Designers will test recyclable materials to determine which provides the greatest buoyancy and then design a dwelling using that material, providing the design and materials to those in need of flood-resistant housing. The foundation must be made primarily of recyclable materials.

Eco project research
This document provides information about climate and natural resources in South Africa, where the floating house prototypes will be tested. It details average temperatures, precipitation levels, and other climate data for Cape Town to help with design considerations. Maps and location information are included to identify areas most in need of housing assistance. Guidelines on recyclable materials in South Africa outline what can be recycled through curbside pickup or drop-off locations to aid recovery efforts from widespread flooding.
Floatable foundation
The document describes a floatable foundation made of recyclable materials that could be used to support dwellings in flood-prone areas. The foundation is made of 14 plastic bottles, a pallet, and rope. It functions by displacing its own weight in water through buoyancy provided by the air in the bottles and spaces in the pallet frame. Calculations show the prototype foundation could support over 100 pounds, enough for a small structure. The design aims to provide flood protection for areas like parts of South Africa that commonly experience flooding.

Diane kohlin train project research
The student has researched designs for an old-fashioned passenger train car to build for a class project. Several designs caught her interest. She liked designs that featured stairs and porches, doors that slid open easily, an open-air layout, rounded roofs, striping on the roof, and circular fans on the roof to keep passengers cool. The extra details helped make the cars look realistic and different from modern train cars.
Project2 3 1a_miniature_train
The document describes a school project where students work in groups of three to design parts of a miniature train engine using CAD software. Each student designs one "challenging", "average", and "easy" part and provides multi-view drawings. As a group, they assemble the train parts in CAD and provide assembly drawings. The purpose is to practice CAD skills like solid modeling, multi-view drawings, assemblies, and dimensioning techniques.
