CODE

Your code needs to be robust and extensible. At WTSi, we help you plan for your future software development needs. 

TESTING

WTSi believes in test-driven electronic product development. We start your project with qualification testing in mind.

Apps

Anyone with a smartphone is your potential new customer.  Let WTSi design *your* device and smartphone app for the Internet-of-Things revolution!

I*O*T

"Internet-of-things" devices are getting smaller and their functionality is increasing daily. WTSi helps you capture your IOT market and keep it.

Plastics

High strength, rigid, fatique resistant, transparent, flexible, scratch resistant, low shrinkage, heat resistant, chemical resistant and more.

Prototypes

When the design is done and its time to get physical, WTSi goes the extra mile to get it right the first time.   

WTSi is a test-driven-design (TDD) company.  That means we thoroughly understand your requirements before we start on the detailed design.  Furthermore, we determine how to test the design before it is built.  Then we document these tests and discuss them with you.   A thorough system-level understanding of requirements is a necessary component of a sound electronic development process.

REQUIREMENTS CAPTURE AND ANALYSIS 

Does your project have simple or complex requirements? It doesn't matter. WTSi will help capture your requirements before the project starts. We will offer suggestions and help you plan for an extensible and robust system to support future plans. WTSi is aware of industry trends and we get advance information from our vendors that our customers may not be aware.  With technology changing at a rapid pace, you don't want to get to market with last year's technology. 

Topics for discussion during requirements capture: 

  • purpose and scope, from both a technical and business perspective 
  • market assessment and target demographics 
  • requirements:
    • functional requirements 
    • usability requirements
    • physical/mechanical requirements  
    • environmental requirements
    • support requirements
    • interface requirements  
  • assumptions
  • constraints 
  • high level workflow plans, timelines and milestones   
  • evaluation plans and performance metrics

ARCHITECTURE

Often a customer will have legacy, industry, or third-party requirements that drive a specific architecture.  One example would be when a medical device requires a certified real-time operating system; this narrows down the selection of candidate target processors. Another example may be that the customer has firmware developers on staff and their processor of choice is possibly an ARM processor...or they like using an IAR (or Keil, or MPLABX) development platform which would also limit the microprocessor selection. Fortunately, WTSi has worked with many development platforms and processors and this is typically not an issue.  However,  we feel the need to have this architecture discussion with our customers to make sure the correct go-forward technical decision is made as well as considerations for cost and schedule.

HUMAN FACTORS 

WTSi has years of experience in all aspects of designing devices for human interaction including the concepts of HMI, UX, UI, and usability.  On the software level, the HMI (human-machine interface) is the code that presents information to, and interacts with, the user; often this information is displayed in graphic format on an LCD display. The user experience (UX) refers to a person's emotions and attitudes about using a particular product, system or service. It includes the practical, meaningful,and valuable aspects of human–computer interaction and product ownership.  The user interface (UI) -  in the industrial design field of human and computer interaction, is the space where interactions between humans and machines occur.  Usability is defined as the ease of use and learnability of a human-made object such as a tool or device.  In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.

ENVIRONMENT

Electronic devices need to be qualified in many different types of environments and choosing the right level of qualification for your product could mean the difference between the ultimate success or failure of your product in the marketplace.  However,  there is no need to incur the costs of 'over'-qualifying your product either.  Whether your product is a consumer, commercial, industrial, or military product, WTSI will help you make sure your product has the right qualification for the right market.

TEST DEVELOPMENT 

Test early. Test often. Always good advice. WTSi has a long history of helping our customers determine that a device we designed works properly, onsite, in their full-up system.  We also provide additional application software for your system and special test equipment (STE) when required.   WTSi has the expertise and equipment necessary to complete your testing
