TOC in maintenance - Article by David Hodges | Ensemble Consulting

TOC in maintenance - Article by David Hodges | Ensemble Consulting | Theory Of Constraints | Scoop.it

[…] Car servicing and repairs not only cost you money—while your wheels are in the garage, your mobility and convenience take a hit, too. There’s just one thing worse than maintaining your assets. Not maintaining them. […] No matter how complex the system, the Theory of Constraints (TOC) can help simplify sense- and decision-making through its fundamental premise that all systems have a constraint which governs the rate at which value flows. […] In adopting the systems thinking approach to maintenance, backed up by TOC operations management, you can be sure you’ll achieve better outcomes than you previously believed were reasonable or possible. You can effectively minimise backlogs and achieve extraordinary adherence to schedule, with all of its cost and downstream benefits. Having the courage to bring new ways of working to the maintenance domain will burnish your reputation as an inspiring and capable managerial leader and fill you with a deep sense of satisfaction from the multifaceted achievements of doing meaningful work.

The reasons for this webinar:
- The multiple definitions of Constraint, even within the TOC Community
- Definitions relate to the time line of TOC
- Throughout the years of working with Eli Goldratt we have gone through the expansion of the understanding of the Constraint and its applications for managing systems
- Oded will share the evolution – the mind-set and the process
- And, will suggest a practical way to get out of the disagreements (among the practitioners) and confusion (of clients and new comers)

Theory of constraints supports automatization | Thinking Logical

Digitalization or digital automation of operations became one of the major buzzes about management improvement for some years. It offers to replace an often manual operation by a computerized and automatized one, sometimes even using Artificial Intelligence. […] There are tons of examples of digital automation projects where that so-called “leap in productivity” gives only very disappointing effects on profits. […] Many implemented automation projects are considered a success but have disappointing results. It happens when the Local optima (the increase of productivity of the operation by automation) is not participating in a global optimum (something that generates money/profits for the whole company/system). […] The Theory of Constraints brings tools and an approach that is taking care of these concerns. […] Every improvement is a change, but not every change is an improvement (Eli Goldratt). […] From the very beginning of the project, T.O.C. provides the necessary tools to define it with maximum confidence. By drawing a Current Reality Tree (a C.R.T. — a logical tree describing the cause-effect relationship of the current situation to uncover the root causes of undesirable effects), it is possible to confirm several critical inputs of the automation project: Is the process really necessary? — some processes are automated while they could be suppressed or highly simplified. Is the automation of the process a solution? — there is no point in automatizing an operation only for the sake of automizing it. …

Standing on the shoulder of the giants by Eliyahu Goldratt, 2008 | Vector Consulting Group

Standing on the shoulder of the giants by Eliyahu Goldratt, 2008 | Vector Consulting Group | Theory Of Constraints | Scoop.it

[...] Toyota’s success is undeniable. Toyota now manufactures as many cars as the traditional leader – GM – and does it while making profits. Over the last five years, Toyota’s average net profit over sales was 70% higher than the industry average, while GM is losing money.1 The success of Toyota is fully attributed to the Toyota Production System (TPS).2 [...] Given that Toyota is the flagship of Japan’s industry, one should expect that Lean would be widely implemented in Japan. Surprisingly, this is not the case. It is commonly known in Japan that less than 20% of the manufacturers have implemented Lean. How come?

It is not because they did not try to implement it. Many companies in Japan put serious efforts into trying to implement Lean but failed. One such company is Hitachi Tool Engineering. Their inability to implement Lean cannot be explained by a lack of serious efforts. [...] There is an explanation to these companies’ failure to implement Lean; an explanation that is apparent to any objective observer of a company like Hitachi Tool Engineering. The failure is due to the fundamental difference in the production environments. When Taiichi Ohno developed TPS, he didn’t do it in the abstract; he developed it for his company. It is no wonder that the powerful application that Ohno developed might not work in fundamentally different production environments. ...

Gil West, Delta’s COO, is committed to continuous improvement and the theory of constraints. “Everybody is laser-focused on the same key operational metrics, rather than each functional silo optimizing their own,” according to Alton Aviation Consultancy Managing Director Jonathan Berger. ...

Effective Solution Modifications - Webinar by Mickey Granot - Wed. 10th Feb. 2020 | TOCICO

Effective Solution Modifications - Webinar by Mickey Granot - Wed. 10th Feb. 2020 | TOCICO | Theory Of Constraints | Scoop.it

Are there cases where key assumptions behind TOC Solutions do NOT apply? Behind each of the TOC applications there are several key basic assumptions.  While those assumptions are valid in many situations, there are cases where they do not apply.  Thus, the regular documented TOC solution should be modified. There are “natural” modifications required like setting buffer sizes, but in other cases the modifications call for adding and/or replacing injections. In this workshop, Mickey, in a conversation with Eli Schragenheim, will present several examples of a need to deviate from the prescribed solution, but still be in line with the key logic and insights that created the original solution, covering all negative-branches.  The examples will cover Production, Projects and Replenishment and through them a pattern on how to identify a valid need to deviate from the solution and how to find the effective modified solution that still conforms to the basic insights.

Liebig's law of the minimum [a close cousin to TOC principles applied to agriculture] - Wikipedia

Liebig's law of the minimum

Liebig law of the minimum, often simply called Liebig's law or the law of the minimum, is a principle developed in agricultural science by Carl Sprengel (1840) and later popularized by Justus von Liebig. It states that growth is dictated not by total resources available, but by the scarcest resource ( limiting factor).

Liebig law of the minimum, often simply called Liebig's law or the law of the minimum, is a principle developed in agricultural science by Carl Sprengel (1840) […]. It states that growth is dictated not by total resources available, but by the scarcest resource (limiting factor). The law has also been applied to biological populations and ecosystem models for factors such as sunlight or mineral nutrients. […] This was originally applied to plant or crop growth, where it was found that increasing the amount of plentiful nutrients did not increase plant growth. Only by increasing the amount of the limiting nutrient (the one most scarce in relation to "need") was the growth of a plant or crop improved. […] Or, to put it more plainly, "A chain is only as strong as its weakest link." […]

Conference in Paris "TOC + Lean + Six Sigma combined"  Free breakfast conference on 15th of January 2020 | Theory Of Constraints | Scoop.it

(Conference in French) Combining Theory of Constraints, Lean and Six Sigma. How and why mix a winning cocktail. Marris Consulting invites you to a breakfast-conference on Thursday 16th of January 2020 in Paris. 8:30 am to 10:00 am. Conference venue: Marris Consulting offices in the Montparnasse Tower in Paris.

Is “TLS” – the integration or combination of Theory of Constraints with Lean and Six Sigma – a good idea? What does it mean exactly? How do they reinforce each other? What are the incompatibilities? Industrial improvement efforts over the past 30 years have been handicapped by quarrels concerning the relative merits of the different approaches and of the supposed incompatibilities or fundamental differences among them. TLS considers, on the contrary, that we should seek to combine them thereby creating a system that contains the best aspects of each movement.
