Costing of EE Products

This is a Crude Costing Formulae based on my Ideas which is called "Gut-Feel Thumb-Rule Methodology." Even Though i am probably the only follower of this popular System, I am sure it is worth a casual Look.

Costing of EE Products

RM - Raw Material Cost         SP - Selling Price to Distributor

Reserves are for Dry days, Employee Fund is to reduce Attrition and Layoff. I was costing the products as a Proprietor, Managing Director and as an R&D Engineer too.

This post is just to enlighten you of the intricacies involved. It is merely the Tip of the IceBerg. You will need a Spreadsheet and lot of foresight and hindsight to make a practical costing.

Management Methodology 

This rule is for products made in good numbers. Large scale production costs may go down. Custom designed products made in small numbers the price may double. The cost of Engineering and IP has not been taken to consideration. It has been covered by a 10% Research Cost.

All this assuming we make products of reasonable quality and reliability. Build a reputation by good customer service when the product fails. So this will add into the cost depending upon the organization.

The grey areas in this costing are "Sourcing quality Raw Materials and Parts". Designing and Engineering "Reliable and Robust Products" . Customer Support at site or field may be expensive and warranty too.

Better to be Honest, Transparent and build a Brand Reputation for a Long Term company Success.

Reliability of Electronic Products

I have been in Product Design, Manufacturing and Marketing of Electronic Products/components. I have also been, like many of you, a customer.

It is very important that the customer gets a Reliable, Sturdy, Usable and Dependable product. This is what makes the Good Brands which in turn add to the Company Reputation and value.

The most important is the "Direct Customer Support" when a product fails or user finds it difficult to operate.  This include Prompt Product Service and Repairs. Any laxity or high-handedness or a Ping-Pong Customer Support can cause acute Brand Blindness that could even become Hereditary. Your brand can be shunned by a Family for generations and they also propagate negative marketing.

Your Product and Your Customer are like Family. Protect it and Nourish it for your own good.

The bathtub curve is widely used in reliability engineering. It describes a particular form of the hazard function which comprises three parts:

  • The first part is a decreasing failure rate, known as early failures.
  • The second part is a constant failure rate, known as random failures.
  • The third part is an increasing failure rate, known as wear-out failures.
  • The name is derived from the cross-sectional shape of a bathtub.

Materials and Inventory Management

The Inventory of a Firm should be Open within an Organization. Searching with a browser, Integrateable with departmental webware/intranet. With a very easy readable non-programmer friendly API.

The Search must be based on Multiple Keywords, Filters or Tags. Dormant Inventory and Parts/Equipment/Furniture not on any live project anymore, Excess Inventory and Obsoleted Parts due to Tech Advancement; should be flagged. This enables other departments to use it, consume it for Maintenance or Research projects or integrate into new designs if not-obsolete.

Components Parts Kits and Materials

If found to be valueless, damaged or worn-out by all departments and responsible engineers, then inventory should be sold or given away. The Employees can be the first customers for an inhouse Corporate Garage Sale. An un-organized, complexly-computerized and non-transparent/blocked Stores will end up in a Flea Market.

Vendor Development and Component Sourcing must be impartial and based on quality, supply consistency and price. Commitment and Collaboration with vendor is good, but only if quality is maintained. Quantities purchased should be little over the needs. Both Overstocking and Understocking can trouble Firms Capabilities.


Engineering Resources and Supplies 

The R&D should maintain its own Inventory. Similarly the Administrative Sections too should have its own Materials Store. This way cost measurements and material maintenance are more effective and simple.

Design as per Inventory

Sometimes a Spartan R&D Engineer needs to know more ...

When you design a new product, we can design it with new types of parts, but it is also important to use parts that are standard to the company's inventory, Also you need to use up the parts which have been accumulated due to a discontinued product line or a failed idea.

This way the design becomes more frugal and efficient. And the inventory valuation more accurate. It also saves the company to build a new part type stock. And finally a balance sheet which is realistic.

What is good for the firm, is good for you.

Engineering the Technology Management

Sometimes even Management has to be Engineered to help it change its ways of thinking in a world that is fast changing. A Planet that is defined by the Consumer or Customer more strongly than any other factor.

Technologies should scale with Infrastructure. Buildings cannot stress the Foundations meant for. Traffic proportional to Road Width. Sync

Technology Management

Raw Materials - Components - Finished Products. The Entire Processing and Design Chain has to improve, if the final Product has to Shine.

Let us use more of our Brain than Brawn, Quality; Reliability & Safety will see a Dawn.

High Value Engineering

In Engineering High Value products are those that are a combination of Precision Mechanical + Electrical + Analog + Embedded Microcontroller.

Study and Learn ?? Examine and Experiment >> Analyze and Establish [o] Realize !!

Engineering Management Equations

Call it Quotes or Ideas or Instructions, these are thoughts that came from me from the past tech experiences of over twenty years.

Technologies should scale with Infrastructure. Buildings cannot stress the Foundations meant for. Traffic proportional to Road Width. Sync. Software should not overwhelm or Overload Hardware.

Raw Materials - Components - Finished Products. The Entire Processing and Design Chain has to improve, if the final Product has to Shine.

Management of Engineering and Technology

Value Engineering
In Engineering High Value products are those that are a combination of Precision Mechanical + Electrical + Analog + Embedded Microcontroller.

Tools Theory Practice
Excellent Tools alone are not enough, The Techniques & Methods have to be learnt, Then the Skills have to be acquired by Strenuous Practice.

Software 7S
The 7S - Software Should be - Simple, Stable, Spry, Slim, Scalable, Sensible, Scrimping.

Incremental Coding
I do incremental coding - code few lines, test, code again, test. Some extra code to interface for test inputs/outputs (virtual instrument). Incremental Coding, Modular. Test Points.

An Engineered Equation
( technologies + skills + processes ) X ( monitored + managed ) = engineering.

Keep Designs Simple
Circuit or Code - Keep it Simple, Modular, Reusable, Documented, Controlled, Compact, Clear, Creative, Maintainable, Testable, Tunable.
