The origins of DSDM Atern and Agile. The DSDM consortium which was formed in 1994, resulted from a need for a different approach to software development. This was in two main areas; the first was for a quicker method, and the second was to develop a scalable and maintainable form of software applications that was suitable for current business requirements. The DSDM consortium harnessed the knowledge skills and experience of various organizations, business users and consultants to help develop this new approach. Modern organizations need to develop and build such applications quickly in order to respond to change, and to actively involve representatives from the business so that they too were committed to the change from the outset. This new method and its techniques were based upon a documented and repeatable lifecycle harnessing an iterative development approach. Accordingly, DSDM Atern and was launched in April of 2007. The focus of DSDM Atern is on delivery of early business benefits, and since its launch, it has been enhanced for various types of project, including those with no technology elements. DSDM Atern is an agile project delivery framework for business solutions and is appropriate for all types of project, not just software development. This framework is able to support both the development and deployment of high speed, high quality business solutions in increments that deliver within tight timescales. DSDM Atern and agile project management have the priority to deliver business value to the customer on time, on budget and to the right quality rather than delivering against a fixed and rigid specification. To do this, time and cost are fixed within an agile project management project, while the functionality and features to be delivered are flexible. A major misunderstanding about an agile project is that project management is no longer needed, and therefore agile is best applied to small and simple undertakings. This incorrect CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 2

assumption leads to another error, and that is than organization must use either agile or traditional project management. A fact that his little known is that DSDM Atern was originally designed to integrate with the PRINCE2 methodology. DSDM Atern can be used straight out of the box allowing organizations two that simply adopt this tried and tested approach. If an organization already uses PRINCE2, then adopting agile project management will enable them to harness the power of both and hence provide a complimentary best practice set of processes. Both agile project management and DSDM Atern have a formally recognize certification process which case the development of professionalism as part of an individual s professional development. The Agile project management certification provides both foundation and practitioner levels which allowed an individual to progress from a basic level to a more advanced level. Project managers will be able to develop their agile management skills because agile project management training is based on best practice, and allows that individual to have a different set of management skills and experience when applying for agile project management positions. DSDM Atern uses five key techniques to do this: MoSCoW prioritization Facilitated workshops Iterative development Modeling and prototyping Timeboxing DSDM Atern also has a considerable life cycle which is designed to create frequent product delivery, iterative and incremental development, and active business involvement plus only delivery of business benefits.

The Seven Phases of the DSDM Atern lifecycle: Pre project Feasibility Foundations Exploration Engineering Deployment Post-project There is flexibility in applying the above phases, for example the feasibility and foundations phases may be combined. In addition, there are various permutations of how the exploration and engineering phases are used within a given project time frame. DSDM Atern has a philosophy that any project must be aligned to clearly defined strategic goals, and be focused on early and frequent delivery of business benefits. In addition DSDM Atern defines EIGHT principles which are fundamental to successfully applying both the approach and its philosophy. The Eight Principles of DSDM Atern: Focus on the business need Deliver on time Collaborate Never compromise quality Build incrementally from firm foundations Develop iteratively Communicate continuously and clearly Demonstrate control DSDM Atern also describes a set of defined roles and responsibilities at both the project and the solution development team levels: Project level roles: The business sponsor, the business visionary, the project manager, and the technical coordinator. Solution development team roles: Team leader, business ambassador all, business analyst, solution developer, solution tester, and technical adviser.

Agile methodology. Agile Easy Read Snippets BOOK 1 The term agile methodology is derived from a set of techniques and methods that have the following characteristics: Development of the products occurs within multiple iterations and this is called iterative development The culture and methodology is based upon simplicity and transparency A flexible approach is taken dependent upon the project situation Self-empowered, cross functional, and self-organizing teams Working useful products are used as a measure of progress Project management approach is empirical and constantly adjusted based on experience This last bullet describing an empirical approach in agile means that everyone involved understands the process and makes contributions to its being refined. For this to work, independent inspection of each product by suitably skilled individuals must occur in order to identify any variances from the acceptance criteria. This further infers that the solution development team must adapt and adjust quickly to minimize further product deviations. As you might expect, there are various approaches that could be considered agile. But the main three that are generally recognized as agile are; lean software development, extreme programming (XP), and scrum. The Downfall of Waterfall. Traditional projects, in stark contrast to agile methodology based projects, use the so called waterfall approach. Since water cannot fall uphill, this approach is based on the fact that as each step in the process is completed and reviewed, the project is either stopped or continues. Going back to a previous step is forbidden. The waterfall approach was first used as a method for materials procurement during World War II and was adopted by early computer developers back in the 1950s and 1960 s. By the 1970s a Dr Royce published the following diagram which clearly shows the derivation of the term waterfall: CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 5

The above diagram suggests that each process step is done in strict sequence, but that is not the fall set of information that Dr. Royce described! He actually added the fact that in the case of a project where the product was being developed for the first time, that the version deployed by the customer should be the second version which of course means that his intention was that the waterfall method should be iterative in nature: CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 6

Returning now to the agile methodology, there is a great deal of common ground between the three approaches of lean, extreme programming, and scrum. These can be summarised as part of the agile manifesto and the twelve agile principles Each approach includes engaging everyone, using the entire team, and applying the principle of collective ownership within a cross functional solution development team. In addition, the emphasis is upon optimizing the whole team within a test driven development harnessing continuous integration product increments. The approach is also summarize fast delivery via small releases using between one and four week sprints. Agile principles of project management and methodology The role of the project manager within an agile project has significant methodology differences as compared with the project manager on a traditional project. For a start, the project manager does not plan the project in detail at the beginning, but rather, creates a high-level plan with the intention of adding more detail at a later point. The second difference for an agile project manager is that they will use different techniques and tools to track progress. But the main difference lies in the way in which the project manager manages the team within an agile methodology. An agile project has a role called a team leader who plans and he or she manages the detailed creation of the products within each Timebox. With SCRUM, this is called a Sprint. The project manager on an agile project is there to ensure that the empowered solution development team has a suitable environment within which to develop the products. The project manager is also there to minimize interruptions to the team s work and to act as an escalation path for any risks or issues which may arise. So the agile project manager must make sure that the solution development team can be productive and to increase their efficiency and effectiveness throughout the Agile project methodology and lifecycle. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 7

The project manager is responsible for communication and for ensuring that information about the projects progress is available to stakeholders while minimizing interruptions to the solution development team. As a mindset, the project manager must keep their focus to always welcome changing requirements to the project, no matter or at what point during the life cycle that they arise. The benefits of adopting Agile Management and Methodology Agile minimizes early planning by creating high-level planning documents allowing development to start earlier than in a traditional project would, and hence bring projects in ontime with the added benefit of project cost savings. The management overhead caused by the project manager having to spoon-feed the work packages to the development teams is removed because the development teams are selfempowered, self-organizing, and self-managing. This allows the Agile project manager to focus on ensuring that the teams can work efficiently and effectively as well as removing any distractions from them doing so. Choosing an Agile Management and Methodology will significantly lower the risk of time and cost overruns, because an agile development team plans and determines how much work they can accomplish within a Timebox and iteration, they are fully committed and empowered to ontime delivery, and this of course is reflected upwards so that the project also comes in on time. Due to the power of prioritization, an agile project delivers the minimum necessary in order to meet the project and business objectives, rather than meet a typically bloated set of requirements or specifications of a traditional project. This typically results in less documentation, fewer meetings, less formal communication replaced by a speedy informal communication, and of course it also minimizes the development work. Similar to the above point, because documentation is kept to a minimum level by making sure that it is just sufficient, more time is available by the development team and the project manager to focus on developing the products / deliverables of the project. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 8

An Agile Methodology uses the approach of iterative and incremental product creation and delivery, and that the lower level, this is carried out within each development Timebox typically lasting only a few weeks. Because prioritization is used to allow dropping the lower prioritized features, then each Timebox can guarantee it will finish on time by delivering the minimum usable subset of the requirements. In this way, if Timeboxes deliver on time, then so do the increments, the project phases or stages, and indeed eventually, the project itself. Because such planning, requirements prioritization, product development, testing and demonstrating occurs within each Timebox and increment, this significantly lowers the risk of product development veering in the wrong direction, or worse, delivering a product that is not what the business needs. Because of the approach used in an agile project, the development pace tends to be fairly consistent mainly due to the active involvement of business representatives, early delivery of benefits, and frequent demonstrations of the product being acceptable to the business. Compare this to a traditional project, where often in an attempt to meet an unrealistic and bloated set of requirements and specifications (not to mention unrealistic milestone delivery dates), forces the development team to work longer and unrealistic hours in order to meet such targets. In summary, the job of an agile project manager working within an agile project consists of: Producing documentation that is just sufficient Supporting the solution development team Minimizing any non-development tasks The creation of simple status information by the team themselves rather than time consuming calculations by the project manager By encouraging the need for change whenever needed Using just in time prioritized requirements to minimize change rework and wasted effort Using the solution development team to create realistic schedules targets and goals By keeping external disruptions to the development team and allowing them to only work on relevant products Early delivery of prioritized products that will realize early benefits to the business and hence enhance return on investment CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 9

Agile Scrum Master Role. Scrum is the most popular agile method when carrying out a software development project, with the Agile Scrum Master performing a key role within the project organization. And since Agile has evolved from software projects, it is natural that the Agile Scrum Master role remains center-stage. But like most methodologies, agile continues to evolve. Today, mainly due to the excellent work carried out by the DSDM Consortium, agile can now be used on any type of project within any industry. It is natural therefore, that the role and responsibilities of the Agile Scrum Master is often split among several roles depending upon the nature of the project. Since the development of the Agile Project Manager qualification (developed in partnership between the DSDM Consortium and the APM Group), an evolved set of role names have developed. Scrum is an iterative approach and uses the sprint as its term for iteration. A scrum team uses inspection throughout the project to ensure that the delivery goals of the project are met. However, there is a relationship between the many disciplines used under the flagship term of agile: CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 10

Here, you can clearly see that Scrum fits neatly at the Team Management level. Of course, the Solution Development Team creates the products or deliverable of the project. DSDM straddles all disciplines, dipping into project management. But the piece that was always missing was the harnessing of the project management discipline and cocoordinating that downward into the solution development team. Further, the disciplines needed to work together for any type of project as well as just software/it projects. The perspective of Scrum: An Agile Scrum Master, sometimes called a project facilitator, is responsible for supporting the solution development team, clearing organizational roadblocks, and keeping process is true to agile principles. A scrum master is a servant-leader who ensures that the solution development team is fully functional, efficient and productive, and as such is an enabling role rather than an accountability role. A servant leader is a role who leads by removing obstacles and distractions while helping the rest of the team carry out their responsibilities. Leaders on agile projects help to find solutions rather than assigned tasks. The scrum master has the following responsibilities: Coaches the project team to adhere to scramble use and practices Shields the development team from external interference Helps remove project impediments Fosters close cooperation between the scrum team and others stakeholders Facilitates consensus building within the scrum team The product owner / business ambassador CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 11

The Agile Scrum Master personal skills. Must be an expert on scrum processes and passionate about agile techniques A good communicator and listener Has organizational influence and able to resolve problems quickly Understands the facilitation techniques to help reach group agreement Ensures the development team have the right information and tools to track progress In this way the members of the scrum team, the solution development team, the product owner, and the scrum master work closely together on a daily basis throughout the project. Product Owner / Business Ambassador. It is worth mentioning this role, sometimes called the customer representative, and they manage the relationships between the customer, business stakeholders, and the solution development team The Product Owner must be an expert on the products including the customer s needs and priorities. The product owner is a member of what might go sure if what you want it I knew a mark of the work to do the solution development team, and make decisions about what the product scope including what products and when deployment is to be made into the life business area. The Agile Scrum Master role options With the creation of the agile project management handbook some two years ago, agile has evolved to suit any project with in any environment, leading to splitting the roles into a project level and solution development team level organization. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 12

The following diagram (also known as the alien baby due to its shape) shows how the agile roles have evolved: Here, it could be argued that the Agile Scrum Master role has been shared between several other roles. However, this does not stop for a single individual from taking these roles on as an individual. The challenge has always been finding a single individual who has the necessary knowledge, skills, and experience to carry out the agile scrum master role. Splitting the responsibilities into more than one role therefore, makes sense as it shares these attributes among the solution development team. Here then, are the roles that COULD share the title of agile scrum master: CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 13

Project Manager. Agile Easy Read Snippets BOOK 1 This role provides high-level management direction to the solution development team and focus is on optimizing the team s environment, removing distractions, planning and managing at a high-level, and being delivery focused. The role includes communicating with senior management, planning and monitoring progress at the project-level, providing resources, and handling any escalated problems or issues from the team. Team leader. This role reports to the project manager and is responsible for ensuring that the solution development team functions effectively and efficiently while meeting their product deliverable objectives. The team leader plans and co-ordinates all aspects of product delivery at the detailed level, and is a leadership rather than management role. Business Ambassador. This role represents the business area being addressed and as such represents those who will make direct use of the solution. The role must ensure that the products are fit for business purpose and is responsible for the day-to-day communication between the project and the business. DSDM Coach. This was formerly called the Agile Coach, but now more correctly is focused to help the team get the most out of the DSDM approach. Summary. As you can see from the above diagram, the environment of agile has evolved and matured to both recognize and include various disciplines within any project or endeavor. Since the term Agile Scrum Master was derived from the use of agile for software development projects, it quite rightly continues to be used. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 14

However, as more definition has evolved around the roles used within a full blown generic Agile project, the Agile Scrum Master role may need to be shared between several individuals, working closely together throughout the project, and contributing their own knowledge skills and experience towards that of an agile scrum master. Agile Testing Approaches Agile testing adheres to the Atern principle of never compromise quality and it takes place within the project lifecycle. In a traditional project testing is usually done as the last phase before product deployment, and some features are therefore tested many months after they were created. In an agile project, testing is a daily part of each Timebox and increment (also known as a sprint), where the creation of such products is not started until the acceptance criteria for that product is first determined and agreed. In this way, agile testing has a far higher success rate than when it is done during the last phase of a traditional project. Testing is often a project's largest unknown risk and for this reason agile testing is carried out as soon as a complete or partial product is made available. Errors, defects or bugs are more expensive due to the amount and complexity of rework fixes when discovered towards the end of a project and hence traditional projects have more inherent risk of cost and time overruns. Whereas in an agile project you can test riskier features in earlier Timeboxes and increments and therefore do so at a point when had sunk costs are still low. In addition, defects are much easier to find when testing smaller amounts of work as well as being easier to fix when discovered shortly after the product was created. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 15

Agile testing concepts. Agile Easy Read Snippets BOOK 1 Fail fast. It is far better to identify and fixed defects within the early phases of an agile project and for this reason, early testing via reviews and inspections should occur during the foundations, exploration and engineering phases. The product does not need to be fully complete be for testing can occur and hence the opportunity to find defects early is enhanced. Regression testing should be carried out following any changes or defect fixes, and Integration testing should be carried out as soon as there is something to integrate rather than waiting until a larger or final integration point. Short development iterations limit the number and complexity of features and in this way makes the whole or partial product easier to test. For this reason, the testing strategy should be thought through during early planning to ensure that each increment and Timebox is not too complex in terms of product creation and testing. The agile solution development team has a solution tester assigned since the knowledge, skills, experience, and preference will be different from those creating the products to those testing it. It is important that whenever possible, that those who fill the roles within the solution development team should remain constant so there is a strong empathy between developers and testers. With the agile project management, the solution development team creates each product against its prioritized requirements and I want to fix any problems or immediately rather than trying to remember how to test and fixed defects on a deliverable that was created many weeks or months previously. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 16

Agile Testing within Timeboxes and Increments (sprints). Agile testing can take place within any of the three iterative steps contained within a timebox; investigation, refinement, and consolidation: Each of these steps is conducted in an Iterative manner giving opportunities for early testing. Agile testing will also happened at the end of each increment, after say, several Timeboxes have been completed, and this is often an opportunity to perform integration testing. There are limitless sequences with regard to the time frame of Timeboxes and increments, and hence every project should have a defined testing strategy which will take cognizance of one of Agile s major strengths, and that is to deploy higher priority products early in to the appropriate life business area. For the same reasons, the requirements or features will have been prioritized using the MoSCoW approach, and so it makes sense to test the higher priority features/products first. This in and of itself, reduces project risk. In a similar manner, some tests will significantly reduce the risk of a product being deployed within the life business area, while other tests have less risk. For this reason, products with a high risk should be tested first. Wherever possible, tests should be made repeatable as it is likely that each test will be run more than once for each product before it is accepted by the customer. All tests along with the acceptance criteria are specified for a given product before it is created. CasaBlanca Publishing 2014 www.agileprojectmanagementprimer.com agile easy read snippets 17

One of the key techniques for an agile project is the use of facilitated workshops, and these can be used very effectively for agile testing. Examples of the use of workshops include: For final fast inspections and walk-throughs of processes, documentation and modeling To create agile testing documentation such as the business testing strategy To resolve and repair any defects found during testing As a risk assessment workshop to prioritize associated tests against product risks Did you know that an Agile Project Manager can command up to 30% more salary?
