	Lean Software Development
		Most of the quality issues in the software components are also because of the linearity in the development process that does not allow the iterations and quality che cks to occur before the components move to the next stage in the development cycle.
		Lean discipline demands instantaneous adaptation to changing market conditions, which is best affected with a flexible architecture that readily accommodates changes, monitoring techniques that detect errors before they occur, and tests that are designed before development begins.
		Lean thinking dictates that scope will take care of itself if the domain is well understood and there is a well-crafted, high-level agreement on the system's function in the domain.

	Lean Software Development
		The software industry is becoming increasingly interested in removing defects after they are created.
		Still today most software is built in long cycles from three months to many years and often not tested until the final step of the process.
		Cycle time for software development is measured in the number of days needed between feature specification and production delivery.

		The Lean principles and methods are being used more and more and have proven their worth within production and administration.
		For example, sales incentives causing software products and services to be incorrectly sold, procurement practices that hinder communication and cooperation, personnel procedures that make it difficult to recruit, motivate and retain talented staff or remove poor performers.
		The lean techniques are relatively easy to implement in a software department but to sustain them wider issues need to be addressed.

		Lean thinking was developed by Toyota as a manufacturing paradigm, which has been extended through that company and is applied to business processes outside of the manufacturing domain.
		That this team of authors has applied it to software development is not as unnatural as it may seem at first glance given how vastly different software is to create versus cars, for example.
		That in essence, is what agile (lean) software development is. When it is possible and done right, agile methods can lead to a dramatic improvement in the quality of the software you create and the amount of profit that it generates.

		In addition, she also has extensive experience with manufacturing, and one of the biggest pluses with this book is how she shows how to transfer principles and practises from lean manufacturing to software development.
		Examples of waste in software development are: extra features (that are not needed now), task switching, waiting, motion (for example document hand-offs), and of course defects.
		Software development is much closer to product development, much more like the work that goes into designing the car in the first place.

		Mary and Tom Poppendieck have transferred the principles and practices from the manufacturing environment to the software development environment (see their Web site for more information) with the goals to identify and eliminate waste through continuous improvement, and to reduce defects and cycle time while delivering a steady stream of incremental business value.
		Lean thinking capitalizes on the intelligence of frontline workers, believing that they are the ones who should determine and continually improve the way they do their jobs.
		Software development methods have different approaches to developing the architecture of a project: Rational Unified Process (RUP) addresses architectural risks early ("If you don't actively attack the risks, they will actively attack you"), whereas XP calls for a "no big design up front".

	Darrell Norton's Blog [MVP] : Lean Software Development Overview
		Lean Software Development (LSD) is the application of lean principles to the craft of software development.
		Lean Software Development is not a management or development methodology per se, but it offers principles that are applicable in any environment to improve software development.
		In software development, waste is anything that does not improve the quality of code, reduces the amount of time and effort it takes to produce code, or does not deliver business value to the customer.

		In software development, as much as 95% of the cycle time and 80% of the development efforts are NOT value-added from the customer's perspective.
		Lean began at Toyota, which is able to develop new car models four times faster than its competitors and with better quality.
		In software development, this means we want to “pull” new features through the process based on real customer demand, not “push” them from the front based on vague assumptions in fantasy roadmaps.

		The authors’ take on this is that software development is more like product development than like manufacturing, so they use lean product development as their inspiration.
		“Set-Based Development” is a good example: they recommend that, when developing a product, you explore the solution space for your various constraints by constructing a large number of alternatives meeting each constraint, and then see if you can use those alternatives to come up with a design that meets all your constraints.
		This is in contrast to “point-based development”: there, you start with one target solution, and repeatedly alter it based on feedback until everybody is satisfied.

		The development team is never loaded beyond its capacity to deliver, and the management team at the highest level of the company adjusts release expectations every week to be sure that teams can meet their deadlines.
		Just about every software development organization I know of has a list of work to do that is far longer than it can hope to accomplish in what customers would consider a reasonable amount of time.
		In a lean environment, the idea is to keep the list of work to be done as short as possible, by dealing with requests honestly at the onset and by not accepting work beyond the capacity of the team to deliver.

	Lean manufacturing - Wikipedia, the free encyclopedia
		Lean is basically all about getting the right things, to the right place, at the right time, in the right quantity while minimizing waste and being flexible and open to change.
		Lean and Toyota Production System (TPS) concepts have also been applied successfully in software development.
		Lean in the Software industry is quite similar to Agile software development - some of which explicitly state TPS as a source of inspiration, including Scrum and Extreme Programming (XP).

	Managing Lean Software Development with Cumulative Flow Diagrams
		If a development team is ready to start a project but they don’t have all the tools and environments needed to make progress then the production rate will suffer badly.
		This would allow us to model the flow of value through a software engineering system as the gradual reduction of uncertainty and the discovery of more and more detailed information until working code which passes appropriate quality control tests, is produced.
		Reinertsen’s and Poppendieck’s observations tie software engineering firmly to the principles of Lean and the lead time for turning an idea into working software must be a critical to the financial success of any software activity.

		If you're not convinced that Agile Software Development practices are at least worth investigating further after you've read this book, then you'll never be convinced.
		It is a well-written guide to the ideas behind Agile thinking, with plenty of references to other sources (the bibliography is 8 pages long); both those showing the benefits of Lean thinking in software and manufacturing, and the "original" sources for various techniques and methodologies.
		This book is aimed at project managers and lead developers looking for ways to improve their software development process, but I would recommend it to anyone who is serious about producing quality software.

	Agile vs. Lean Software Development
		Lean is responsible for colossal improvements in productivity and quality over the past 32 years and is used successfully by industries that range from manufacturing and logistics to product development.
		Lean initiatives, on the other hand, focus on the core task of identifying and eliminating waste while driving key decisions outward in the development cycle.
		LEAN has nothing specifically to do with software; it is about streamlining production systems by eliminating waste, having the “right” process, leveraging people as the most flexible resource in the system, and being disciplined about “when” decisions are made.

		Agilists argue that we should not try to learn lessons from manufacturing, since software is not the assembly line (which is true) and the way things are done in the manufacturing world, only make sense there (which is not true, as it turns out).
		I'm a big believer in "agile is not just for software" so whenever I come across examples where agility is used elsewhere, I tend to get very excited about it.
		Though Detroit now understands how the Japanese do it, and they've been using more agile ways since the nineties, I can't help but think that Lean has something to do with better and cheaper cars they make, and therefore with the problems GM is having.
