Summary

For some time, management thinkers (and manager of thought) have stressed the urgent need for new approaches to changes in society. In this paradigm is the bottom line pre-eminence to the top: The company focuses on developing new sources of revenue from new products and services while maximizing revenue from existing lines through innovative marketing and operating costs, rapidly changing customer needs and tastes. The new type of society is mainly agile.

The dictionary defines “nimble” as “agile and active: fast and flexible”. For decades, big business into a supertanker, which can be turned grim with the speed has been compared. Leaders at the lack of creativity and innovation relates to them, on the bridge of the supertanker, but their own decision-making and command structures stultify efforts – including those that promote themselves -. the development of new and rejuvenate the old

The concept of Agile

new variability is required in all major areas of strategy and tactics. Like it or not, every business into a strip (or sheet), an eco-system of alliances include partnerships, subsystems, processes, operations, employees, etc., none of which n is not always guaranteed. Hierarchy, dominant market share, vertical integration and economies of scale are the traditional means of controlling the complexity of large organizations – forever. Today, all four pillars have been undermined.

hierarchy has very little space in an organization that depends on the free-thinking, innovative self-management at all levels. Market share once impregnable were undermined by aggressive newcomers in many markets. The vertical integration has no meaning if special horizontal component suppliers of technology and economies much larger than that of the general vertical reach.

kaleidoscope telescope

The metaphor of the administration were kaleidoscope telescope. Where managers can focus on their own needs, seeing little need for the peripheral, they now have a need to constantly changing shapes, sizes and colors from which they try to understand. It sounds like a daunting task. It would have been impossible to track the progress of information technology that facilitates and accelerates the company to save quick relieve him of expenditure control to coordinating joint efforts, the status quo in the future.

All companies

really agile share this positive attitude to change and the future. What makes such as the agility? The first answer is paradoxical and agility that is based on stability: just as the Olympic divers need a solid platform to start their diving acrobatics, if a company has to be firmly established to perform strategic twists and turns with speed. An important basis is a good starting point and good customer supplied meet the vendors. This respect can be obtained from compatible Internet. Quality, excellent service and great novelty

The second answer is decentralization, which diffuse power, where it is most needed and can be used effectively. Let people take the initiatives that are best for their customers – wanted in the famous case microprocessor, a Japanese company, the computer a set of Intel chips for its latest machine. An engineer named Ted Hoff won immortality by why all the circuits on a single piece of silicon can be placed. You can: took over other engineers and their prototype of a large fortune. The discipline was that of technology, not the executive.

central management

central role of management in the agile enterprise is a party set high standards and see that they are. Management is also responsible for ensuring that decentralization is authentic. He uses his strength, if they are useful to ensure that its powers are not used, where they will interfere. This is another paradox, but the company thrives on agility paradox. He knows there is no right answer that the best answer at the time that will be replaced as soon as get better, and there is always a better answer

C. a fundamental principle of kaizen, continuous improvement is noted and the essence of total quality management. For years, many traditional managers, TQM seemed foreign in both directions – an unwelcome import and uncomfortable to Japanese control freaks. In fact, TQM is the work of an American, W. Edwards Deming was born remarkably, who believed passionately in the development of free workers authoritarian controls so that they can do their work better – much better. Whether companies are using TQM or its close relatives, Six Sigma, Agile principle is the same: the individual control over their own work and improving it to give, individually or in groups. So, you are necessary? You can:

•

aware backup of old and new?

mixture

• Working with individual growth real?

• combine short, medium and long-term, without any of the three
? • receive both discipline and freedom?

• continue the commercialization of the human race? to link

• With the globalization of the marketing of local, national and regional level?

• the customer what they want to do while you?

• To strengthen the former while nurturing the news?

• throw caution to the wind, but also an excessive risk?

•

grow fast and not over-use of the company over the “limits to growth”

Sometimes, these limitations are obvious, how to use the lack of generation capacity and the provision of equipment, or unsaturated markets. More often, the boundaries are less specific, is of several elements, including competitive actions and reactions, market trends, the responsiveness of the organization, environmental factors, etc. Among along the boundaries seem almost arithmetic mean of a company, and earnings per share by 15% of the compound in five years to double to increase, has quadrupled in ten years, and eight times in fifteen. The larger the base, the most unlikely growth.

decentralized fleet

One workaround good of a CEO who wanted to replace decentralized its fleet of motor boats, supertankers expressed Fast and powerful self-contained units that could (as opposed invited to supertankers) overnight be changed, as they continued their chances and prevented their threats. Few entrepreneurs do not dictate it was easy or fast and make these dynamic changes in their fleets stability agility. Top-down initiatives with resistance from senior and middle -. Resistance to win treacherous and difficult

The agile response to the article from top to bottom to remove initiatives -. a reform that is to say ultimately easier, thanks to informal, internal changes, which is the ratio increased agility in all areas of business, none of these changes more important than the spread of multi-disciplinary, cross-functional teams, made to projects that last only before the project. Nobody manager ordered that address a fundamental reform, but now today can easily half their time in ad-hoc teams, the building blocks of society spend agile.

returns team could extend beyond the borders of society, the territory of the customers, suppliers or competitors. The team includes the formal structures and can create their own approach. Again and again, management of project teams has proven its ability to make impossible deadlines possible. “Skunk Works”, project teams and other groups are called “new heroes, new products and services.

can go

Leadership teams from hand to hand, created by the authority of expertise is very relevant. Kaleidoscopic Company Breaks the old ideas of rank, status, and chains of command and communication. The company is agile people based what comes naturally, intuitively and consciously. Many observers were impressed by the fact that the people in the crowd in general, more changes, than they do as individuals to resist -. confused even if the proposal clearly beneficial to their individual interests

is holding the status quo

This mentality reinforces the obstructive mass society as the guardian of the status .. quo This is automatically the enemy of the news he is stubborn, talented people like Ted Hoff within each organization: the ultimate test of agility, is whether the organization of the frustrated individual talents or eat his words, the new agile approach maximizes the return on Human capital. workers by promoting and strengthening the use of human talent, which, depending where they are necessary, but

necessarily by the use of new technology for all -. including those of information and communication. The companies always have machinery for . the control and dissemination of information was arthritis companies followed when the machine messaging has become more important than the message “The goal was laudable.. disciplined to achieve orderly and efficient basis, the results were dismal: The value defines much less than their Part Agile companies treat their rooms as more important than the whole – and end with a company that exceeds the total number of parts

Anyone who has to manage software development projects knows that software is not.. simple. to coordinate successfully and dealing with promoters customers, challenges team members, technology issues and changing needs and the project leader of the most experienced.

advanced projects in an environment that includes an offer of rapid change can be even more difficult. However, change are the people with the desire, the basic rules of the game software and accept the empirical nature of software development are faced with many choices. To benefit from the evolving nature of agile development, community leadership must now also on seven priorities with agile development is concentrated. Courage, Context, Courses, Cadence, cost, commitment and creativity

7 C of Agile Management

Courage

also one of the four core values in Kent Beck’s declared Extreme Programming courage a much broader and more strategic demands beyond the limits of the programming software development, many interfaces take -. customers, other project teams, customer support, professional services, external stakeholders, Human Resources and many others – <. p> and the confidence to make the record and be ready to positive changes in the face of tradition can be a risky business, but ultimately very rewarding experience

Agile development is definitely not for the faint of heart. This does not mean that the project management will not be easy, but that any new type of business practice and hard work required. Agile leaders can not shy away from mistakes, especially during the early iterations. With agile development, at least the failure is usually a few weeks, at which point you evaluate the situation and accordingly adjust may be limited. These early iterations should be used to learn, adapt and stabilize.

teams and people in general good, not what they practice. In agile development, planning, estimation, testing and delivery come every few weeks as opposed to once a year. Therefore, teams quickly set a rhythm. By focusing on developing the elimination of barriers to the title and thus the rhythm built on putting agile leaders of the stage for improving the predictability and success. While still in the heat of the battle of Software Delivery, looking back, most agile teams after six months to see improvement, and I wonder how they have successfully delivered the software in any other way.

Context

With much of the “basic infrastructure project (scope, priorities, estimates, plans, risks, etc.) in a state of the river, it has never been more important to lead and manage the actions and decisions in a global environment. Although the functional value can often drive the details of a project, companies need to drive values project aims to help. Force difficult decisions about the company and the context. Project as soon as possible

Get as simple as possible answers to key questions such as: •

What are the vision for the project

•

What are the primary objectives and operational factors of the project

• What

the values that the most important decisions for the project and product are

• What are the expectations of project sponsors and stakeholders

The answers to these questions form the basis for future decision-making and a wire that can prevent a project from out of control. In addition, the degree of visibility of these priorities as a basis for conflict management and negotiations are with those involved. Several teams document the answers to these on a single page or a web page project, and keep them visible throughout the duration of the project. These reactions often than a bar, hold responsible are used.

Price

Background and current are complementary ideals. Whereas context defines overall circumstances, course defines direction and progress. Just because some agile approaches was not considered in detail, for 1-2 iterations do not think that the longer range planning is not necessary or helpful to be enticed. Planning software to serve as a roadmap for long-term business intermediaries and important decisions for the project. Iteration, milestone, and release plans remain essential elements of planning and measuring progress. Note that you intend to further reduce levels of trust, but a roadmap for at least three to six months is necessary to continue to reality for a changing environment.

Make a concerted effort, at least at each iteration to achieve the goals to review, reconcile overall direction, review periods and deadlines, and connect the gaps. Reality has shown that rarely is the time on software projects carried out. This is especially true in the world of agile development. be agile development, change accepted and even encouraged for commercial reasons, so that also provide early and often willing to communicate early and often. Unlike traditional environments where projects of the feedback loop to extend layer or even take years, can be far more successful agile project teams

directly with companies and key management as often as every iteration.

nce

You can always communicate the concept of cadence or rhythm, one of the positive impact of agile development. Most successful agile teams get into a powerful groove that can significantly benefit team confidence as well as the reliability of the project.

teams can even serve low delivery iterative and incremental in its sense as Mitigator significant risk. Instead, deliver once a year or more, agile teams deliver working, tested, installable software every iteration. In this environment, unexpected decline Loose Ends clearly the defects are much easier to manage, integrated builds are second nature and deployment into production much easier and foolproof. It is not to say that some problems will not occur, but they are much easier to manage.

In the early practitioners of this rhythm team is an objective as soon as possible. For experienced practitioners, this rhythm simplifies the task of leading agile development. Many agile teams have reached much higher degree of predictability than conventional methods. Simply with a quantifiable, accurate history worked estimation and delivery can greatly simplify the design and increase reliability.

Cost

Even agile development can not escape its impact Financial Software Development. The challenge and the advantage of agile development is an opportunity cost for the companies value and benefit of its customers throughout the process to justify, as both opposed end. In addition, instead of project management cost centers, the agile development also provides the ability to see software development as an investment, with the aim of achieving the best possible returns earlier in the development cycle.

If not the same direct impact on the business benefits that you have no costs for the firm to extract value sooner rather than later, continues to align business goals and technology, and adapting to the changing dynamics of the group is invaluable. Because of this ability to change, that financial considerations should continue to remain front and center. Although the cost model for most agile development projects is fairly straightforward, “cost per iteration” is not something that many organizations have experience or understand. Fortunately, many consulting firms and development organizations, the transition to a simplified project costing, made by multiplying the approximate cost per person for the whole team on the length of an iteration to calculate fiscal impact (ie 000 euros per iteration). Although not as sophisticated as human resources and traditional models of resource allocation, this type of analysis and reasoning can be just as accurate.

commitment basis

During the development of a system can be software modules can be viewed in terms of their obligations. introduced (in terms of consumption resources, data needs, etc.) constraints of their own structure and behavior and their relationships with other modules. The Comet system uses explicit representation and reasoning with commitments to software design and lead development process in particular for software developers to make decisions that are in use again. Developers can include with the commitments that meets an existing module must investigate, and how to change commitments, when modules are changed.

Creativity

creation software venture is one of the most creative activities, the people. The main limitation of the software is the human imagination and the limits are self imposed. Software Engineering from the model we see a linear, sequential model of software development, greatly reduces our ability to create truly great software.

With the use of creativity, it is possible to create a truly great software. The only problem is that it requires that developers the freedom to explore different models, and the ability to design, select the best the spirit of the regulations as writing papers requirements.

Software creativity arises when we take time to explore the design space of possibilities, rather than only comes to fixing the first solution in mind. A good example is my current favorite development tool, Borland Delphi closely integrated with its code and graphics editor allows a developer to make changes, be it by text editor or other tools. Well, if they do not go with a Java or C + + version. (1997 more) C + + Builder and JBuilder are two answers to that request.

One result is that developers have to worry about creativity. Although most people is a creative activity to attribute the idea, software development, few people think they are really creative. The effect of this is dramatically on the software development. Few developers will learn how to really evaluate models, as a consequence of being able to assess the design, the need for alternatives if the first fails.

wisdom in dealing Agile

Whitewater Interactive System Development with Object Models (Wisdom) meets the requirements of small development teams that are necessary to build and the highest care quality interactive systems (Nunes & Cunha, 2000). Wisdom methodology consists of three main components:

1. Software process to user-centric, scalable, rapid prototyping and model

2 is based. A number of conceptual modeling notations that support the modeling of functional and nonfunctional components.

3 A philosophy of project management standards for the use of open tools and documentation

Benefits of Agile Development

What are the benefits of Agile methods are based Management & Development> p? The benefits are considerable and include:

•

shortening the development cycle by 75%

• Improved stability workload

• greater use of the workload that the development of large software systems with a fixed number of developers to change

• More flexibility on the direction and development plans,

• Improved quality by earlier feedback from customers.

Limitations of Agile Development

What are the limitations of agile development methods are p> p ??? limits Agile Methods:

• Agile development methods do not adapt. The integrated approach is to understand exactly for some, where the project is difficult. In a typical environment, management wants to know when each phase such as design, code, or test is complete. Thus, through different stages of the iteration, it can be difficult to understand, process if • the project on track

Agile methods are not very large teams. The approach works only for the teams small and medium-sized enterprises •

Agile development requires individuals highly skilled and motivated officers who are not always zero. Agile focuses on people with Premium

Reconcile Six Sigma with Agile Software Development

There is often a conflict between cultural groups of adaptive software / Agile groups and process improvement in organizations trying to implement a method such as Six Sigma. Objectively there is no fundamental contradiction between the two. Agile development focuses exclusively on the needs of the customer identifies with minimal administrative costs. Six Sigma focuses on identifying the needs of customers in the application of strict controls. The difference lies in the implementation, the ultimate goal is the same. Therefore, it may have little or nothing to “reconcile”. It can apply a question of understanding, if for every approach to integrate and at what level for everyone in the organization standard process.

Compare the possibility of a software development project is usually carried out with Agile approaches such as Six Sigma, the problem of improving an existing business processes. The Six Sigma DMAIC process is very similar to the approach of the Agile project. Located in the DMAIC approach to quantify the expected results on the voice of the customer, a key concept in both approaches. The measure DMAIC as the outline of the causes to keep up with effects. The improvement of the DMAIC just means what he says. Control of DMAIC is analogous to the known concept of lifelong learning Agile, even in the science of the organization as a double-loop organizational learning. It is not known or inconsistent here, at least at the conceptual level.

Six Sigma and Agile development are improving, both to reduce failure rates and customer satisfaction given. They represent very different attitudes, as is done when. In response to ensure the failure of the process control for him for the success of the project imposes severe Six Sigma process control even more difficult to gain a comprehensive understanding of cause and effect. The Agile approach based on an entirely different philosophy, to reduce the formal controls give qualified professionals the freedom, critical thinking and creativity to implement unique problems. Both approaches are effective in different situations.

In a limited area, such as a manufacturing process, it is perfectly logical to have a comprehensive understanding of cause and effect. In a service operation can be useful also because it’s important to minimize changes in individual factors (remember that the main objective of Six Sigma, to minimize the variation). An example often used in Six Sigma training, a pizza delivery service that promises delivery within, keep customers and ensure the pizzas are all in line wants – height of the shell, the regularity of the diameter, the color of skin.
