The GPS Mathematical Model emerged from Gladys West's keen observation of problems that others had simply accepted as unsolvable. The ideation phase was characterized by relentless curiosity and systematic investigation.
Why was this needed? Gladys West saw clearly the limitations of existing approaches and the suffering they caused. How would it work? Through careful analysis of the problem's root causes and creative application of available knowledge and materials.
The early conceptual phase involved extensive note-taking, sketching, and mental experimentation. Gladys West drew from their background in space & aerospace, but also looked beyond their field for inspiration. They understood that breakthrough innovations often come from connecting ideas from disparate domains.
The design and brainstorming phase for the GPS Mathematical Model was intensive and iterative. Gladys West understood that moving from concept to reality required meticulous planning and creative problem-solving.
The first designs were rough - pencil sketches on paper, annotated with measurements and material specifications. Gladys West created multiple variations, each exploring different approaches to solving the core technical challenges. These early drawings reveal a mind wrestling with fundamental questions of form and function.
While Gladys West was the driving force, the design process benefited from feedback and collaboration. They consulted with: - Technical experts who could evaluate feasibility - Potential users who provided practical insights - Material suppliers who explained what was possible with available resources - Financial advisors who helped understand manufacturing costs
The first design was far from the final one. Through a process of constant refinement, Gladys West improved upon each iteration:
1. **Version 1.0** - The initial concept, bold but impractical in certain aspects 2. **Version 2.0** - Addressed manufacturing challenges, simplified complex components 3. **Version 3.0** - Enhanced user experience, improved reliability 4. **Final Design** - The synthesis of all learnings, ready for prototyping
Choosing the right materials was critical. Gladys West evaluated options based on: - Availability and cost - Durability and performance characteristics - Ease of manufacturing and assembly - Environmental conditions the invention would face
The final material selections reflected a balance of ideal performance and practical constraints of the era.
The journey from design to physical prototype was fraught with challenges, setbacks, and breakthroughs. Gladys West approached prototyping with both scientific rigor and creative flexibility.
Constructing the first working model of the GPS Mathematical Model required resourcefulness. In 1979, manufacturing capabilities were limited compared to today. Gladys West often had to: - Source materials from multiple suppliers - Commission custom-made components - Adapt existing tools for new purposes - Solve unexpected technical problems on the fly
The first prototype was assembled in a modest workshop, with Gladys West personally overseeing every detail. When it was finally complete and they activated it for the first time, the moment was both triumphant and humbling - it worked, but not perfectly.
The initial prototype revealed numerous issues that weren't apparent in the design phase: - Mechanical components that wore out faster than expected - User interface elements that proved confusing - Performance metrics that fell short of targets - Manufacturing steps that were too complex or expensive
Gladys West documented each problem meticulously, understanding that failure was information. They ran the prototype through rigorous testing protocols, measuring performance, identifying weak points, and gathering data.
Over the following months, Gladys West built multiple prototypes, each incorporating lessons from the previous version:
Before moving to manufacturing, Gladys West conducted extensive validation: - Stress testing under extreme conditions - Long-duration reliability trials - User testing with the target audience - Safety verification to ensure no harm
The final prototype was tested until Gladys West was confident it would perform reliably in the real world.
Transitioning from a working prototype to full-scale manufacturing presented an entirely new set of challenges. Gladys West had to think beyond invention and become an entrepreneur and production manager.
The approach to manufacturing the GPS Mathematical Model was influenced by several factors: - Available industrial capacity in 1979 - Capital requirements and funding sources - Skill level of available workforce - Supply chain for raw materials
Gladys West developed a manufacturing plan that outlined every step from raw materials to finished product. This included:
The manufacturing process for the GPS Mathematical Model involved multiple stages:
1. **Raw Material Preparation**: Sourcing and preparing base materials to precise specifications 2. **Component Fabrication**: Creating individual parts through cutting, forming, machining, or molding 3. **Assembly**: Bringing components together in precise sequence 4. **Quality Control**: Inspecting each unit to ensure it met standards 5. **Testing**: Functional testing before packaging 6. **Packaging**: Preparing products for shipment and storage
Gladys West was obsessive about quality. They established rigorous inspection protocols: - Incoming material inspection - In-process quality checks - Final product testing - Statistical process control to identify trends
Any unit that failed inspection was either reworked or scrapped - Gladys West's reputation depended on reliability.
Initial production runs were small, perhaps dozens or hundreds of units. As demand grew and processes were refined, Gladys West scaled up production: - Investing in more efficient machinery - Streamlining workflows - Implementing assembly line techniques - Training additional workers - Establishing multiple production shifts
Manufacturing at scale revealed problems: - Supply chain disruptions requiring alternate suppliers - Quality inconsistencies demanding process adjustments - Worker training challenges necessitating better documentation - Equipment breakdowns requiring maintenance protocols
Gladys West addressed each challenge systematically, building a robust manufacturing operation.
Creating the GPS Mathematical Model was only half the battle; getting it into the hands of those who needed it required an effective distribution strategy. Gladys West understood that impact depended on accessibility.
In the 1970s, distribution networks were different from today. Gladys West explored multiple channels:
The GPS Mathematical Model initially launched in a limited geographic area - often the region where Gladys West was based. Expansion followed a strategic pattern:
1. **Local Market**: Proving the concept and building reputation 2. **Regional Expansion**: Extending to nearby cities and states 3. **National Distribution**: Reaching across the country 4. **International Markets**: Exporting to other nations (when applicable)
Distribution required creating awareness. Gladys West employed various marketing tactics: - Print advertisements in newspapers and magazines - Demonstrations at trade shows and exhibitions - Word-of-mouth from satisfied customers - Testimonials and case studies - Public relations and news coverage
Determining the right price point was crucial: - Cost-plus pricing to ensure profitability - Market-based pricing considering competitors - Value-based pricing reflecting benefits delivered - Volume discounts to encourage larger orders
Gladys West balanced affordability with sustainability, wanting the GPS Mathematical Model accessible while maintaining a viable business.
Post-sale support was part of the distribution strategy: - Providing clear instructions and documentation - Offering repair services and replacement parts - Responding to customer inquiries and complaints - Gathering feedback for product improvements
Gladys West understood that satisfied customers became advocates, driving further distribution through recommendations.
The early days of the GPS Mathematical Model were a mix of excitement, anxiety, and constant adaptation. Gladys West had poured years of effort into bringing this innovation to life, and now it faced the ultimate test: real-world use.
The moment when the first customer purchased the GPS Mathematical Model was unforgettable. Gladys West often personally delivered early units, eager to see the product in use and gather immediate feedback. These first customers were pioneers themselves, taking a chance on an unproven technology from a new inventor.
Initial sales were modest. In the first month, perhaps only a handful of units sold. Gladys West personally knew each customer, understood their use case, and followed up religiously to ensure satisfaction.
The feedback from early users was invaluable:
Gladys West took all feedback seriously, often implementing rapid improvements to address concerns.
The first production runs revealed the gap between prototype and manufacturing: - Component suppliers who couldn't maintain quality consistency - Assembly processes that were slower than projected - Quality control that caught more defects than anticipated - Costs that exceeded initial estimates
Gladys West spent long hours in the factory, troubleshooting problems, retraining workers, and refining processes. The early days required hands-on leadership and willingness to do whatever was necessary.
The early commercial phase was financially precarious: - Initial capital being depleted faster than planned - Revenue lagging behind projections - Need for additional funding to sustain operations - Pressure from investors or creditors for results
