Tailor your Message To Gain Support for your Agile Initiative | Enabling Agility - 0 views

  • Connect Agile’s Benefits to your Company’s Priorities
  • aying that Agile is “better, faster, cheaper” may not be enough to cause a company to be willing to go through the often-painful process of cultural and process change.  You could implement Agile, but you could also try Six Sigma or Lean.  Saying that Agile is a general get-better remedy puts it in line with many other get-better methods.
  • f they don’t see a meaningful update from us, at least once a quarter, we’re going to get kicked out of the game.  We’ve all acknowledged that as we’ve gotten bigger, our processes have become more cumbersome and now is the time to do something about it.  Agile will give us the ability to regain that rapid pace of delivering innovations to market that we were know for in our early days.”
  • ...21 more annotations...
  • ur last two releases have looked like me-too updates, where we are just barely keeping up with our competitors
  • We’ve been losing market share
  • If you can refer to a specific business issue and show the linkage, you are much more likely to get a receptive audience.  Here’s an example.
  • The CFO, developer and QA manager have different roles in the organization and their needs are different.  If you want to enlist their support, be sure you know who you are talking to and what they value.
  • Use Focused Messages for Key Individuals or Groups
  • certain volume of people who are enrolled in the idea of Agile before you’ll see adoption start to accelerate,
  • People have specific needs in their role and they want to understand how Agile will affect and benefit them directly.  
  • Developers, on the other hand, probably wants to know if they will have interesting work, the opportunity to learn new things and the ability to make an impact on the company’s products.
  • a QA manager is probably interested in hearing how Agile helps enrich the QA profession.
  • The focus isn’t on Agile, its on business, as it should be.
  • The easiest way to find out what interests someone is to ask them.  When you meet, leave plenty of time for talk.  Motoring through a well-rehearsed Agile presentation usually doesn’t work.  A lot of times I’ll have slides with me, but they are a backdrop for the conversation.  I’ll refer to slides when it helps move the conversation along, but otherwise don’t use them.  You might want to forget slides altogether and just draw things on a whiteboard as necessary.  This technique is particularly useful with an individual or a small group.  
  • Take it One Step Further: Collect Data to Gain Insight
  • you’ll be most effective tailoring your message if you invest some time conducting data through a series of structured interviews. 
  • First, you’ll need a small set of questions prepared for the interviews.  Here are some examples. What is working with our current methodology? What’s not working with our current methodology? How do you think Agile would help our organization? What concerns do you have about Agile?
  • Interview a wide range of people: developers, testers, business analysts, managers, product managers, senior management, project managers and someone from finance. 
  • When you conduct the interviews, it is good to have one interviewer who has the primary responsibility for talking and the other person who has the primary job of taking notes.  You can switch off roles each interview so no one person gets stuck in either role.  Here’s how I typically start off.  
  • stories that people tell about the organization and make sure you write them down
  • I put all of the information we’d gathered into a mind-mapping program (Mindjet) and grouped like things together.
  • Make sure you keep interesting stories intact.  Specifics will help you make your cases
  • When there’s numerical data, people engage with a presentation in an entirely different way than they do when there are stories.  I find stories more effective, but do what works for you.
  • As an Agile evangelist, you job is to get Agile deployed effectively.  Along the way there are many people will be willing to go out of their way to help if you effectively speak to their interests and concerns.

Alistair.Cockburn.us | Agile contracts - 1 views

  • Venture-capital financing model This can be used with any of the above contract forms. In this model, the sponsor gives a round of financing for a certain amount of work, and the contracted company must produce results in order to get more funding. The sponsor can cut their losses at any time if they are not getting the results they need. They can presumably alter the terms of the contract after each work period. The result of a work period need not be working software; it could be a paper study, or a requirements document, or anything the sponsor selects. The venture-capital finance model works well with agile providers, since the agile provider is used to delivering useful, working software early and regularly. I find it an odd irony that the venture capital financiers running start-ups that I have encountered don’t take advantage of their own model to the extent agile teams do. The venture financiers let the evaluation markers occur too far apart in time. If they attached funding to monthly releases, that would oblige the start-up team to think through what it really can accomplish each month. The monthly progress would give the financiers a better sense of the start-up company’s real progress.

  • Bob Martin’s idea Bob Martin of Object Mentor posted an interesting variant to get around this problem: a base fee per story point, plus a lower-than-usual (close-to or below cost) fee per hour. This biases the contracted company’s to deliver early, but gives them some protection in case work proceeds slower than expected. Bob Martin described it this way:”[A]gree to pay a certain amount for each point completed, plus a certain amount for each hour worked. For example, let’s say you’ve got a project of 1000 points. Let’s also say that a team of four has established an estimated velocity of 50 points per week. This looks like about an 80 man-week job. At $100/hour this would be a $320,000 job. So lets reduce the hourly rate to $30/hour, and ask the customer for $224 per point. This sets up a very interesting dynamic. If the job really does take 80 man-weeks, then it will cost the same. If it takes 100 man-weeks then it will cost $344,000. If it takes 70 man-weeks it will cost $308,000. Notice that this is a small difference for a significant amount of time. Notice also that you, as developer feel strong motivation to be done early, since that increases your true hourly rate.” I have not seen that model in action myself, but several people have written in recommending it.

The Product Owner in the Agile Enterprise - 0 views

  • Responsibilities Vary by Software Business TypeSince the business mission, organization, operating methods, roles, titles and responsibilities differ dramatically across industry segments, it follows that the patterns of agile adoption vary across these segments as well
  • Information Systems/Information Technology (IS/IT) -teams of teams who develop software to operate the business; accounting, CRM, internal networks, sales force automation and the like. Customers are primarily internal to the enterprise.
  • Embedded Systems (embedded) - teams of teams who develop software that runs on computers embedded in other devices - cell phones, electronic braking systems, industrial controls and the like. Customers may be either internal or external to the enterprise.
  • ...17 more annotations...
  • Independent Software Vendors (ISV) -teams of teams who develop software for sale, including products like network management, supply chain management, mobile applications, etc. This segment now also includes the rapidly emerging Software as a Service (SaaS) vendors. Customers are external to the enterprise.
  • So far, former developers/tech leads with business sense and good project management skills seem to be the best fit.
  • ultimate user (mobile device user) is fairly far removed from the major technologies
  • Ryan went on to note that the title of "Program Manager" also performed a similar role in some larger scale contexts:
  • Embedded Systems Example - Symbian Software Limited
  • Clearly, the development of a mobile phone operating system is a highly technical endeavor
  • mention this because I suspect that the Technical Marketing Specialist role, where it exists in the ISV today, could make a good role model for the Agile Product Owner in today's larger ISV
  • the development process does not lend itself quite so easily to the traditional, customer/user facing, agile Product Manager/Product Owner roles. However, the Product Owner role must still be successfully addressed in this highly technical context.
  • All our POs come from engineering teams and are senior engineers with product or customer experience.
  • one PO to two team mapping typically, rarely 3 teams, sometimes 1
  • IS/IT Examples
  • role/title of the Business Systems Analyst
  • is often a reasonably good fit for the Product Owner role.
  • In the larger IT shop, I have also seen the role filled by Project Managers
  • In many cases, the self-managing and team-based planning lightens the workload for the project manager in the agile enterprise, and they often have the domain knowledge, inclination and insights necessary to fulfill the Product Owner role. Therefore, many have the time, skills and inclination to fill this role.
  • In our case, our product owners are in IT. They are the liaison to the business and in many cases speak for the business
  • Our Business Systems Analysts in IT are filling the role of Product Owner. Their previous responsibility of documenting detailed business requirements and rules now falls to the entire team in the form of user stories and acceptance tests

EE Times - Using agile methods in medical device development - 0 views

  • FDA and other regulatory agencies fundamentally want to see that your product has safety in mind. To do so, they require complete traceability through the hardware and software. There is even a fairly new standard, IEC 62304, adopted worldwide that is wholly focused on software traceability from requirements through architecture to tests.
  • Medical devices companies are going primarily agile to respond to change and effectively manage technical complexity by collaboratively building solutions with their partners and customers to ultimately deliver what the customer wants before the competition does.
  • demo the new functionality created after each iteration to your customers, using web-based meets. Using these tools enables you to get immediate feedback from your customers throughout the project. Continuous customer feedback reduces the risk of building the wrong solution. The fact is in most cases you can’t make the release cycle more frequent since it includes giving tests to regulatory agencies. This is a tedious process that makes sure the device is safe. Doing the whole release cycle more frequently can be way too time consuming.

  • ou could also give a version to select customers as long as it will not be directly used for care or diagnosis on current patients. The idea there is the customer gets the current iteration in house for say a blood analyzer. They could load it with real patient data and test out the new functionality as long as it is not used to diagnose an existing patient, since it has not gone through regulatory
  • agile development has gotten so popular in medical device companies that the AAMI (Association of Medical Instrumentation) is currently working on new guidance for mapping agile to a medical standard called IEC 62304.
  • In conclusion, agile development works and is being used in medical device development. The issue is you need to have a good toolchain that allows for complete traceability across the entire lifecycle in order to comply with standards. It is also very important to integrate and test frequently. This, in turn, leads to the need for build automation. With all of this in place, agile development for medical devices becomes much easier to make work.

How to make a LOT more money using agile - 0 views

  • How to make a LOT more money using agile
  • More frequent releases
  • expectations must be set for releases to be smaller but still have significant marketable value.  It also means managing scope for smaller releases so the value can actually be delivered to meet the expectations.  If we make the assumption these two pre-requisites can be handled, then we can also assume faster releases are possible.  Yes, I know, releasing software is expensive, requires other groups, etc.  For now, let’s assume all of those costs are negligible compared to the potential results and see where we end up.

  • team of 8 people work on a project for a year with an anticipated ROI of 100% after 2 years.
  • $1,000,000 (approximately) in 12 months to build the product
  • get $2,000,000 in revenue within the 12 months following release.
  • ROI is calculated as $profit/$invested which in this case is ($2,000,000-$1,000,000)/$1,000,000 or 100%
  • cash expended, which in this case exactly matches the investment since we did all of the investment prior to receiving any return.
  • Let’s assume that scope can be managed so the product can be delivered in two phases, each taking 6 months.
  • each piece of the product is worth about half of the revenue value of the complete product
  • 6 months at an investment of $500,000 to build the first piece
  • 6 more months at an additional cost of $500,000 to complete the second half
  • after 6 months revenue starts to be brought in for the first release
  • the amount of revenue during the first 6 months of release of the first half of the product would be $500,000 ($2,000,000 for full product for 12 months = $500,000 for half product for 6 months).
  • matches the cost for building the second half of the product, so the cash expended is actually only $500,000 for building the product vs. $1,000,000 for building the product in one step.
  • After phase 2 of the product is completed it too starts to bring in revenue.  We now have the complete product, so we can get full value of it during each time period.  In other words, during the next 12 months it will generate $2,000,000 in revenue.  This brings total revenue to $2,500,000 which means our ROI is now 300% (higher profit divided by smaller investment - $1,500,000 profit / $500,000 invested).
  • Month Expense Revenue Cash (Profit) Total Revenue 6 $500,000 $0 -$500,000 $0 12 $500,000 $500,000 -$500,000 $500,000 24 $0 $2,000,000 $1,500,000 $2,500,000

James Shore: The Art of Agile Development: Stories - 0 views

  • "Non-Functional" Stories AllyPerformance OptimizationPerformance, scalability, and stability—so-called non-functional requirements—should be scheduled with stories too. Be sure that these stories have precise completion criteria. See Performance Optimization for more.
  • Spike Stories AllySpike SolutionsSometimes programmers won't be able to estimate a story because they don't know enough about the technology required to implement the story. In this case, create a story to research that technology. An example of a research story is "Figure out how to estimate 'Send HTML' story". Programmers will often use a spike solution (see Spike Solutions) to research the technology, so these sorts of stories are often called spike stories.

GE Healthcare Goes Agile | Dr Dobb's - 0 views

Therefore, our "definition of done" — that is, the list of activities that add value to the product such as unit tests, code coverage, and code reviews — turned out to be lengthy.

Original Scrum-ban Article by Corey Ladas | Lean Software Engineering - 1 views

  • A problem with the basic index-card task board is that there is nothing to prevent you from accumulating a big pile of work in process. Time-boxing, by its nature, sets a bound on how much WIP that can be, but it can still allow much more than would be desirable.
  • then you need another mechanism to regulate the “money supply.” In our case, we simply write the quantity of kanban in circulation on the task board, and allocate new cards according to that limit.
  • You might have a simple principle like: prefer completing work to starting new work, or you might express that as a rule that says: try to work on only one item at a time, but if you are blocked, then you can work on a second item, but no more. In our example, that rule gives us an effective WIP limit of 6.
  • ...6 more annotations...
  • Just because anybody can have more than one item in process doesn’t mean that everybody should have more than one item in process. A problem with our multitasking rule is that it locally optimizes with no consideration of the whole. An implicit total WIP limit of 6 is still more WIP than we should probably tolerate for our three workers. A limit of 4 of 5 total items in process at one time still allows for some multitasking exceptions, but disallows the obviously dysfunctional behavior of everybody carrying two items
  • The ready queue contains items that are pending from the backlog, but have high priority
  • Here we’ve broken down in-process into two states: specify and execute. Specify is about defining whatever criteria are necessary to determine when the work item can be considered complete. Execute is about doing the work necessary to bring that work item into a state which satisfies those criteria. We have split our previous WIP limit of 5 across these two states. Specify is considered to take less time in this case, so it is given a limit of 2. Execute consumes the remaining limit of 3. We might change this ratio as time goes on and our performance changes.
  • Adding the specify-complete column communicates to the team that a work item which was previously in the specify state is now ready to be pulled by anyone who wants to move it to the execute state. Work that is still in the specify state is not eligible to be pulled yet. If the owner of a ticket in the specify state wants to hand it off, he can put it in the complete buffer. If he doesn’t want to hand it off, he can move it directly into the execute state as long as capacity is available.
  • e will also need some agreement about what results to expect at each handoff. We can do that by defining some simple work standards or standard procedures for each state. These do not have to be complicated or exhaustive. Here, they are simple bullets or checklists drawn directly on the task board.
  • The next event we might consider for scheduling planning activities is the concept of an order point. An order point is an inventory level that triggers a process to order new materials. As we pull items from the backlog into the process, the backlog will diminish until the number of items remaining drops below the order point. When this happens, a notice goes out to the responsible parties to organize the next planning meeting. If our current backlog is 10, our throughput is 1/day, and we set an order point at 5, then this planning will happen about once a week.

James Shore: The Art of Agile Development: Spike Solutions - 0 views

  • About Spikes A spike solution, or spike, is a technical investigation. It's a small experiment to research the answer to a problem. For example, a programmer might not know whether Java throws an exception on arithmetic overflow. A quick ten-minute spike will answer the question.
  • Performing the Experiment The best way to implement a spike is usually to create a small program or test that demonstrates the feature in question. You can read as many books and tutorials as you like, but it's my experience that nothing helps me understand a problem more than writing working code. It's important to work from a practical point of view, not just a theoretical one.
  • Writing code, however, often takes longer than reading a tutorial. Reduce that time by writing small, standalone programs.
  • ...2 more annotations...
  • Design Spikes Sometimes you'll need to test some approach to your production code. Perhaps you want to see how a design possibility will work in practice, or you need to see how a persistence framework will work on your production code. In this case, go ahead and work on production code. Be sure to check in your latest changes before you start the spike and be careful not to check any of your spike code.
  • If you anticipate the need for a spike when estimating a story, include the time in your story estimate. Sometimes, you won't be able to estimate a story at all until you've done your research; in this case, create a spike story and estimate that instead

Using a Task Board with One Remote Team Member | Mike Cohn's Blog - Succeedin... - 0 views

  • Try to get the one person to move to where the rest of the team is.
  • Having one remote is a cost that must be borne by the full team. For the right person, it’s easily worth it. But sometimes, the person who is remote has not special skills, knowledge or experience to justify the added hassle.
  • continue to use the physical task board–it is simply too beneficial to the collocated team members to give it up in favor of a product backlog tool, especially if team members are already used to it and like it.
  • ...3 more annotations...
  • The remote person in this case could identify during the daily Scrum what he or she will work on and not need further interaction with the task board until selecting the next task. Here, the remote person doesn’t really interact with the task board at all and interacts only with the team. Not ideal as I’d like the person to see the tasks, but this can work in some situations.
  • more common is for the ScrumMaster to take on the responsibility of updating an electronic version that mirrors the physical task board
  • One good way of minimizing the time the ScrumMaster spends doing this is to mark the cards on the physical task board. The mark indicates “I’ve updated this task. Please update it in the online task board.” I like to use Post-It flags for this
