Every action that brings you closer to your goal is productive. Every action that does not bring you closer is not productive, even if it seems so. The Goal of every business is to make money. Likewise, activities that do not bring you closer to making money are not productive.

Beware of defining subgoals that do not really drive toward the Goal, like production efficiency, team size, money raised, etc. Organizations can be measured by 3 metrics: Throughput, Inventory, and Operational Expense. Many companies focus primarily on decreasing operating expense, which can lead to unproductive behaviors that stifle throughput.

Instead, switch your mindset to increasing throughput. The bottleneck of the system determines the throughput of the entire system. By definition, the throughput of the system cannot be The goal eli goldratt summary than the capacity of the bottleneck.

Where is the weakest link in the chain? This means the value of an hour lost at the bottleneck is equal to the value of the entire system. Constraints can be equipment, people, or policies. Increase capacity at the bottleneck through a variety of interventions. Prevent idling by running the bottleneck all the time, ensuring inventory upstream of the bottleneck, and preventing back-ups at the bottleneck.

Improve quality of upstream work to prevent bottleneck working on poor-quality work. Outsource bottleneck capacity to outside the organization. If both the bottleneck and non-bottleneck go full steam ahead, the non-bottleneck will produce surplus inventory, which adds cost and causes traffic jams.

To coordinate this, use Drum-Buffer-Rope Drum: Every action that brings a company closer to its goal is productive. Every action that does not bring a company closer to its goal is not productive.

Defining the Goal is critical.


Without money, the company is dead. Do not deceive yourself into picking a subgoal — like decreasing cost per part, employing good people, manufacturing efficiency, product creation, quality, satisfaction, cutting-edge technology, market share.

None of this matters unless it meets the Goal. Be wary of separate departments overoptimizing their subgoals without meeting the main goals. Like purchasing being more cost-effective and renting warehouses to store excess inventory.

If you improve efficiency at one step without increasing overall output, you are not being more productive — you might even be causing an excess inventory and increasing cost per good sold. Eg Imagine if you added a robot at one part of the assembly line.

To justify the cost, you drive it at max capacity, which requires feeding it a lot of upstream supply, and also causes downstream accumulation. The cost-per-part at that step is high, but the system overall suffers.

Net profit the more positive the better ROI relative, to tell what the base is Cashflow to make sure company stays alive How do you convert these highest-level metrics to ones that are more actionable day-to-day? Ideally, you should try to improve all three at once.

Be wary of a change that affects only one of these metrics — there may be second-order effects that backfire. Eg reducing labor to reduce operational expense may decrease throughput.

If you make a subpart more efficient, you do not raise your competitive advantage if it does not increase output or reduce cost.

The real metrics to care about are total products produced and cost per product; increasing efficiency at one step may aggravate the other steps.

Fallacy of Average Production Rates In manufacturing, a balanced plant tries to match average capacity of every resource exactly with market demand.

Any resource beyond the average rate is seen as extraneous, so it is either put to use or eliminated. However, two interconnected concepts make the balanced plant backfire, thus decreasing throughput, increasing inventory, and increasing carrying costs: Dependent events — one part of the chain depends on the upstream part.

Statistical fluctuations — many factors cannot be predicted precisely Even at an average steady state rate, there are fluctuations in production.This is the second installment of the blog series on TokuDB and PerconaFT data files.

Bill Peach, the division vice president and Alex’s boss, has stormed into the plant furious about a late order. Amazon is now the largest Internet retailer in the world, and Jeff Bezos recently became the wealthiest person in the world. Amazon increasingly penetrates our everyday life, from being the first stop for our online shopping to interfacing with our .

The 'default' model starts with production process improvement and might eventually progress to new product development if the incentives . This page includes a summary of The Goal, a novel by Goldratt and Cox that introduces the Theory of Constraints.

The behavioral implications associated with the three methods are fairly easy to see. First, consider that the direct costing statement reveals the amount of operating income that will result under each of the three methods when the number of units produced is equal to the number of units sold.
