Theory of Constraints

Theory of Constraints
The theory of constraints (TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it. TOC adopts the common idiom "a chain is no stronger than its weakest link." This means that processes, organizations, etc., are vulnerable because the weakest person or part can always damage or break them or at least adversely affect the outcome. History[edit] An earlier propagator of the concept was Wolfgang Mewes[2] in Germany with publications on power-oriented management theory (Machtorientierte Führungstheorie, 1963) and following with his Energo-Kybernetic System (EKS, 1971), later renamed Engpasskonzentrierte Strategie as a more advanced theory of bottlenecks.

Critical Chain Project Management Critical chain project management (CCPM) is a method of planning and managing projects that emphasizes the resources required to execute project tasks. It was developed by Eliyahu M. Goldratt. It differs from more traditional methods that derive from critical path and PERT algorithms, which emphasize task order and rigid scheduling. A critical chain project network strives to keep resources levelly loaded, but requires that they be flexible in start times, and quickly switch between tasks and task chains to keep the project on schedule.

Case Study: How Kanban Increased Conversation And Improved Flow Shared by: Dan Rough Date posted: September 18, 2012 While writing the content for our course, we scour the web for case studies to support the points we’re making. Frequently we find information telling us how something is being done; we rarely find information describing why people have decided to use one practice or another. We feel understanding the why is often the most important aspect. What is Lean The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources. A lean organization understands customer value and focuses its key processes to continuously increase it. The ultimate goal is to provide perfect value to the customer through a perfect value creation process that has zero waste.

The 2014 Gift Guide: What To Get Creatives (And Those Who Want To Be More Creative) Geese are fattening, old men are awaiting haypennies (whatever those are) in their hats, and Christmas (or whatever) is fast approaching. And while you almost certainly have great ideas for the boring people in your life (what up, gift card!), more creative friends/family members/co-workers require more consideration: their gifts have to be both genuinely useful and clever enough to make it clear that you know them well. To that end, we've assembled a can't-miss gift guide for the creative folks in your life, to ensure that they'll be inspired and equipped going into 2015.

Local Shared Object Local shared objects (LSOs), commonly called Flash cookies (due to their similarities with HTTP cookies), are pieces of data that websites which use Adobe Flash may store on a user's computer. Local shared objects have been used by all versions of Flash Player (developed by Macromedia, which was later acquired by Adobe Systems) since version 6.[1] Flash cookies, which can be stored or retrieved whenever a user accesses a page containing a Flash application, are a form of local storage. Similar to that of cookies, they can be used to store user preferences, save data from flash games, or to track users' Internet activity.[2] LSOs have been criticised as a breach of browser security, but there are browser settings and addons to limit the duration of their storage. Storage[edit] Local shared objects contain data stored by individual websites.

Event chain methodology Event chain diagram Event chain methodology is an uncertainty modeling and schedule network analysis technique that is focused on identifying and managing events and event chains that affect project schedules. Event chain methodology is the next advance beyond critical path method and critical chain project management.[1] Event Chain Methodology Principles[edit] Flow. Discover Problems and Waste in Kanban – 2 Years Later Almost 2 years ago I published the Flow. Discover Problems and Waste in Kanban post. The idea was quite simple: visualize the flow of a single user story or bug, and track their life cycle to Done: Theory of Constraints Overview Introduction Let’s Start By Stopping For A Moment Slow down, block out the rest of the world for a moment, and take the time to consider the following. Have you ever found yourself in a situation where you were waiting for someone to provide you with something, something that you must work on, and in-turn, which you had to pass on to someone else? Someone else who may have also been waiting for that particular piece of work?

Ilan Eshkeri Ilan Eshkeri is an English film composer. Early life[edit] Eshkeri was born in London.[1] During his childhood, he learned to play the violin and guitar and later went on to play in a rock band. Eshkeri attended Leeds University where he studied music and English literature. Color Color (American English) or colour (British English; see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates.

Theory of Constraints Projects Critical Chain Critical Chain Project Management – A Performance Engine For Projects Critical Chain Project Management is the Theory of Constraints logistical application for project operations. It is named after the essential element; the longest chain of dependent resourced tasks in the project. The aim of the solution is to protect the duration of the project, and therefore completion date, against the effects of individual task structural and resource dependency, variation, and uncertainty. Agile LEGO – Toyota Kata an alternative to Retrospectives « Hakan Forss's Blog My name is Håkan Forss and I’m a Lean/Agile Coach at Avega Group in Stockholm. In this short story I want to introduce Toyota Kata as an alternative or as a complement to agile retrospectives. But let me first introduce you to the team. This is a tightly knit, cross-functional and very experienced team. They have been working with agile for a few years, mostly using Scrum.
