Why lean

Below are descriptions of maintenance methods that can be implemented alone or integrated within the TPM program. Breakdown maintenance Breakdown maintenance is maintenance that is done after the event, we wait for the machine to break down before we take any action.

The demand pulls or purposes for which the EVP may seek these metrics might be to conduct a budget review or undertake a store redesign. Formal service-level agreements SLAs for provision of the business service may monitor transaction speed, service continuity, and implementation speed.

The table further illustrates how other users of the point-of-sale service — notably, cashiers and shoppers — may be concerned with other value metrics, demand pulls, and SLAs.

Having identified and described a value Why lean, implementation usually proceeds with construction of a value stream map — a pictorial representation of the flow of information, beginning with an initial demand request or pull and progressing up the value stream.

Although value streams are not as readily visualizable as their counterparts in lean manufacturing, where the flow of materials is more tangible, systems engineers and IT consultants are practiced in the construction of schematics to represent information flow through an IT service.

However, alternatives to these off-the-shelf applications may be more efficient and less wasteful in the mapping process. One alternative is use of a configuration management database CMDB[12] which describes the authorized configuration of the significant components of an IT environment.

Workload automation software, which helps IT organizations optimize real-time performance of complex business workloads across diverse IT infrastructures, and other Why lean dependency mapping tools can be an additional help in value stream mapping.

The analysis may adapt and apply traditional efficiency techniques such as time-and-motion studies as well as more recent lean techniques developed for the Toyota Production System and its derivatives.

Meanwhile, tighter business and consumer credit, [16] a steep decline in the housing market, [17] higher taxes, [18] massive lay-offs, [19] and diminished returns in the money and bond markets [20] have further limited demand for goods and services.

When an economy is strong, most business leaders focus on revenue growth. During periods of weakness, when demand for good and services is curbed, the focus shifts to cost-cutting.

Although such actions may be necessary and prudent, their impact may be short-lived. More recently, however, companies have moved many mission-critical business functions to the Web. Lean IT initiatives are accordingly becoming less of a peripheral interest and more of an interest that is intrinsic to the core business.

Green IT[ edit ] Though not born of the same motivations, lean IT initiatives are congruent with a broad movement towards conservation and waste reduction, often characterized as green policies and practices. Green IT is one part of this broad movement. Whereas practitioners of lean manufacturing can apply visual management systems such as the kanban cards used in the Toyota Production System, practitioners of Lean IT must use enterprise IT management tools to help visualize and analyze the more abstract context of IT value streams.

Moreover, whereas much of the supporting theory and methodology is grounded in the more established field of lean manufacturing, adaptation of such theory and methodology to the digital service-oriented process of IT is likewise only just beginning.

British airports authority BAA and airline British Airways BAwhich has exclusive use of the new terminal, used process methodologies adapted from the motor industry to speed development and achieve cost savings in developing and integrating systems at the new terminal.

Whether driven by a fear of job losses, a belief that existing work practices are superior, or some other concern, such changes may encounter resistance. For example, a lean IT recommendation to introduce flexible staffing whereby application development and maintenance managers share personnel is often met with resistance by individual managers who may have relied on certain people for many years.

Also, existing incentives and metrics may not align with the proposed staff sharing. Unfortunately, fragmented efforts at Lean IT contribute little benefit because they lack the integration necessary to manage cumulative waste across the value chain. To this end, lean IT consultants have recently proposed so-called lean consumption of products and services as a complement to lean production.

Deployment and commercial support[ edit ] Deployment of lean IT has been predominantly limited to application development and maintenance ADM. This focus reflects the cost of ADM.

On submitting this request, provisioning of all hardware and software requirements would then be automatic through a lean value stream.Further, there is no consistent "lean method" ask different lean people a question and you are likely to get a different answers. Lean folks claim that many are doing lean wrong, which begs the question.

The Mantra of Lean. Inventory is a recurring theme in Lean Manufacturing. Many authors and lecturers on Lean Manufacturing say it is "evil". Question: "What does it mean to lean not on your own understanding (Proverbs )?" Answer: Proverbs is a familiar passage to many: "Trust in the LORD with all your heart; and lean not on your own understanding.

In all your ways acknowledge him, and he shall direct your paths.". Join Steven Brown for an in-depth discussion in this video, Why Lean Six Sigma?, part of Lean Six Sigma Foundations. Lean Six Sigma is a combination of two powerful process improvement methods: Lean and Six Sigma. Lean Six Sigma decreases your organization’s costs by: Removing “Waste” from a process.

Lean Manufacturing & Operations. Lean is about eliminating waste. It consists of a set of attitudes, philosophies, principles, analysis tools and specific work structures that form a production system.
