Organization From Chaos...

• The Goal– Point of sale & Inventory system for a resale

shop type of retail environment.

• The Challenge– #Products X #Brands => **Big Mess**– Flexible pricing

• The Initial Target– Lafayette HFH ReStore (currently delivered)

PURDUE UNIVERSITY

Managing a Mess

• A hammer's a hammer.– Group similar items together.

• The hotter the fridge the hotter the price.– Track large ticket items on an individual basis– Price dictated by item's characteristics.

• Condition• Brand• Features• Etc…

PURDUE UNIVERSITY

Mechanisms for the Madness

• Software organized by function– Sell– Donations– Inventory– Reports

• Use existing tagging schemes as much as possible– UPCA Bar Codes (The U.S. Retail Standard)

• Categories for grouping items

PURDUE UNIVERSITY

Principles for Success

• Expandability– Physically– Functionally

• Compatibility– Hardware– Software

• Ease of use– If it isn’t used nothing else matters

To Infinity and Beyond(Direction for future work)

• Expand to support EAN-13 and UPCE bar codes

• Fully implement the notion of a “Donor”• Custom cohesive visual icon theme• Enhance the inventory tab• Add graphing & printing features to Reports• Linking all ReStores via a Napster like

network (Potential new national level project)

PURDUE UNIVERSITY

Old Approach

• Team created tutorials

• Reviewed locally by Construction Managers followed by national approval

• HFH dealt with distribution of tutorials

PURDUE UNIVERSITY

Design Shown to HFHI

• Publicly generated tutorials

• Reviewed• Posted to the web• Rated by public and

HFH• Edited by public and

PURDUE UNIVERSITY

Design for Next SemesterWe will create a generator that will be used by Wisconsin EPICS team to create tutorials for HFHI. Also, we will create an editor for them as well so that they can edit the revisions given to them by HFHI.

Problem Statement• Problems for HFHI

– No centralized survey administration and data collection system.

– There is no concrete quantitative data showing the benefits of the Habitat program to the community, both locally and nationally.

– Homeowner information and responses must be securely collected, transferred, and analyzed

PURDUE UNIVERSITY

Methodology• Our Solution

– Having a centralized secure server database for survey information and homeowner responses

– Homeowner ID’s will be requested from the server but will be kept in paper records as to ensure the security of the information being recorded.

– The web-based program will consist of three main parts:

• A Survey Generator• Homeowner Response Collection/Input• Statistical Analysis

PURDUE UNIVERSITY

Tasks

• Completed– Beta Version Written (Spring 2004)– Design Documentation (Fall 2004)– Server up and running (Fall 2004)– Version 1.0 Delivered (Spring 2005)

• Outstanding– Version 2.0 (Additional Features)
