The Journey Begins
Posted by Marc Onetto, former EVP of Worldwide Operations for Solectron

Electronics: High Tech, Innovation, Cool Marketing on one side, mediocre quality, delayed availability for new product, inventory write-offs on the other side. This is the now famous imbalance of our industry.

The wrong solution: forecasting, reworking, recalls.

The potential breakthrough: expand the world best supply chain methods -The Toyota Production System- also know as lean manufacturing to electronics.

Today there is about 90% of wasted time and energy in the electronics supply chain, i.e. time and energy that the end customer will not pay for. This waste appears as bloated inventory, component shortages, low yield on new products, and perhaps the worst: major recalls (as illustrated by the recent PC battery fiasco).

If all the players in the supply chain from OEM to ODM to EMS to component manufacturers, from engineers to manufacturers to marketers work together to eliminate waste our industry could have both exciting innovation and world class quality and customer satisfaction.

This is what this weblog will be about...suggesting practical lean solutions to traditional breakdowns in the electronics supply chain. I will address first the fundamental management principle behind lean: set a very exciting vision, link your lean deployment with clear financial goals, drive all improvements from the customer back into the supply chain, empower your people, leverage the knowledge of Toyota trained advisors, collaborate with rather than squeeze your suppliers to reduce costs, and above all never tolerate that bad quality be passed on down the line. Then we will review in depth how to implement some of the key tools of lean: value mapping, fast changeover, fool proofing, demand management. We will spend a whole weblog on total quality; address the famous question of the rapport between lean and six sigma. We will also see how to combine Design For Six Sigma and Production Preparation Process to assure world class quality in new designs. In depth collaboration with suppliers to eliminate costs and achieve market based costing will be discussed.

I will propose ways to establish collaboration with distribution to make sure that demand variations transmitted to the supply chain reflects genuine end-consumer consumption patterns rather than self imposed large batch variability. We will conclude with a description of the benefits for all parties involved in the lean transformation: customers, suppliers, shareholders and all personnel involved in the supply chain.

See you all in my next blog entry…

Assembly Line harmony – Myth or possibility?
Posted by Shlomi Izikovich, a Valor product manager for the Process Engineering Market

Assembly line harmony is a target many process engineers strive to achieve. From many interactions with my customers I learned that the first step toward such flow is about creating a clear manufacturing process definition that brings the right inputs at the right time for each workstation on the line.

Manufacturing Process Definition (MPD) includes workstation inputs such as parts, part data, programs, solder paste, optimal stencil design and documentation. In addition it contains tooling definitions and routing instructions. Such an excess of different inputs and process definitions brings forth a number of challenges:

Variability of Workstation Inputs
- The time it takes to generate many diverse workstation inputs and instructions from different systems slows down delivery time and creates a bottleneck in the engineering department. Workstation inputs should be rapidly generated and be ready for production.

Synchronization of Workstation inputs
- Failing to synchronize between workstation inputs may reek havoc in production times and delivery dates. For example, if the stencil workstation will not have the best stencil template, placements will have to be re-worked, usually manually, hence postponing delivery dates of finished goods.

Timing of Inputs
- In order to shorten cycle times on the production line, workstations should be fed simultaneously. In order to allow the PCB to flow smoothly from one workstation to another, all workstation inputs should be delivered in an error free manner.

The best way to address these challenges is to begin with an understanding of how each challenge affects your production floor. The second step is to develop a manufacturing process framework that allows you in a very clear way to deal with each of these challenges.

The goal is to be able to generate a coherent and comprehensive process definition which makes the whole assembly line work like a finely tuned machine, or in other words: turn the concept of assembly line harmony into reality.
