Challenges in implementing Agile philosophies and methodologies in an SDLC wo...houseofyin
The government has increasingly been asking for contractors to use Agile methodologies to write and deliver better software. Environmental and contractual obligations often make that a hard thing to do. Add to the challenge the project's requirement to also adhere to SDLC processes, and you've got quite a challenge on your hands. What do you do, and how do you handle it?
SRA International's Robert Sfeir and David Kane discuss how to go about mapping and integrating Agile philosophies and methodologies in different situations, discuss experiences from the trenches, and offer an informative approach to solving some of these problems.

Dr Robert Phaal - Technology roadmapping: a case studyJIC
Technology roadmapping: a case study
Best Practice Workshop: Technology Roadmapping
Brno, 5 February 2013
Dr Robert Phaal (Centre for Technology Management)
In this talk, Suze explores a case study from her recent work in a London agency, where, working for a large retail client, the programme of work moved from a project-based delivery model incorporating Scrum to a more product-based model. Drawing on aspects of Kanban, Design Thinking and Lean Startup, and implementing a dual-track agile approach, the team is now ‘thinking more product’.
Suze will delve into how the organisation has shifted to this model and how it coped with the change. She will talk through some of the difficulties that she experienced along the way and how these issues were mitigated, and provide take away techniques to help in your organisations.

Fuel Good 2018: Quality is not an Act, It's a Habit: Best Practices in System...Sparkrock
Testing is very important and can be more challenging and complex than analysis and design. This presentations shows tips and tricks on how to ensure you're not missing any important detail when it comes to your Sparkrock solution.
How do you know if you have too much process, too little, or just the right amount? If you ignore process completely, unpredictability and chaos can follow. If you define the process to the nth degree and follow it religiously, the work grinds to a halt. Janet Gregory shares her experiences about how to find the tastiest balance of process and creativity for your projects and organization. She proposes that a formally defined process is sometimes necessary, but that it should be the exception. Explore with Janet the many variables—team size, complexity, criticality, organization structure, and culture—you must assess to find just the right balance. Learn how to make existing processes better by adding visibility to the process, getting team members’ input, and adapting documentation you need. Learn how to transform complicated processes into simpler ones—such as reporting a simple “thumbs up” or “thumbs down”—and go home with new tools to sprinkle on just enough process.
EffectiveUI's Ari Weissman (Lead Experience Architect) and Lys Maitland (Senior Experience Planner) spoke at Denver Startup Week 2016. Discussion description:
Test early, test often.
It’s a mantra that’s been proven successful time and again when it comes to innovation and design. So why aren’t you doing it? In the start-up world, when everything is moving so quickly, it can be easy to overlook or postpone collecting feedback from real people because of cost, time, or lack of preparation. Don’t let those things stop you. Valid data can be captured cheaply, quickly, and with half-finished products and strategies.
This talk will cover:
What is user testing and why is it important
How to plan for user testing
What are ways to make testing cheaper
What are ways to make testing quicker
How to test with different fidelities of concept and design
How to collect data more frequently
Opportunities for getting the whole team engaged
What to do with the insights/outcomes of research
Gamification in outsourcing company: experience report.Mikalai Alimenkou
Most of us used to hear word gamification only for end user engagement into product usage. Some of us know about usage of similar approaches in product development teams to improve and tune development process. But almost nobody believes that gamification is possible in the context of outsourcing companies and teams. This talk is experience report of gamification usage on very large project with detailed reusable framework demonstration. If you want to bring some fun and really engage your team, then this talk is for you.
Николай Алименков "Геймификация в аутсорсинговых компаниях: практический отчет"Fwdays
Большинство привыкли слышать слово "Геймификация" только в контексте привлечения конечного пользователя в процесс использования программы. Кто-то знает о применении данного подхода в продуктовых компаниях с целью влияния на процесс разработки. Но мало кто верит, что подобные практики можно внедрять и в аутсорсинговых компаниях.
В данном докладе будут представлены практический отчет о подобном внедрении, рассмотрены детальный фреймворк для повторного использования в проектах различного типа. Если вы хотите добавить интереса и привлечь команду в свой проект, то этот доклад для вас.

From Project to Product: “Big Rock” Constraints and How to Overcome ThemCprime
Project-based thinking and process is often the largest inhibitor of achieving agility. It explains why the notion of ‘Project to Product' has gained such popularity to the point of becoming a buzzword in recent years.
Despite the enthusiasm about becoming a product-driven organization, many companies still hang onto their old project-based ways due to some “big rock” constraints, including funding and separation of IT and business.
So, what can you do to make a successful shift?
Join Anne Steiner, Cprime’s VP of Product & Technology, to explore the challenges you may face in your product agility journey and how to overcome them. We’ll explore:
- Common constraints you may encounter when shifting from project to product and how to address them
- How to shift to product based funding models
- The role of the product manager
- Benefits you’ll experience with true product agility

7. What are you trying to learn?
■ User experience and product definition
• “Will this design fit 95% of my target population”?
• “Is it intuitive for users to walk up to my product
and wave to wake it up?”
■ Technical and engineering challenges
• “How do I make a bluetooth antenna work underwater?”
• “Will my design generate adequate pull force”?
■ Product architecture tradeoffs
• “How do users respond to the product size that results
from the minimum viable battery life?”
Who are you trying to impress?
■ Yourself, a partner, an investor, a CM, etc?
ASK THE RIGHT QUESTIONS
7 | S Y N A P S E C ON F I N D E N T I AL
8. Now that you have your questions, WHAT TYPE OF PROTOTYPES SHOULD YOU MAKE?
Looks like: Production intent size and appearance, non-functional
■ Great for user interaction questions, and impressing key stakeholders
■ Lower cost and lead time than functional prototypes
Works like: Explores some functional aspect of the design
■ Great for for addressing technical risk regarding functionality or performance
■ Saves resources by not worrying about size, appearance
Looks like/Works like: Captures both function and appearance of the intended
design. May be created with a different method and scale from final design.
■ Closer to a real product - answers form, interaction, and function questions
■ Generally higher cost, longer lead time than looks like or works like
MAKE THE RIGHT PROTOTYPES
8 | S Y N A P S E C ON F I N D E N T I AL
9. ■ Don’t forget about testing! Plan to spend a substantial
amount of your prototyping time and budget on testing
■ Testing types
• Reliability - drop testing, water ingress, thermal,
chemical compatibility, etc.
• User interaction
• Regulatory
• Performance variation over multiple units
■ Think through what can be tested on each prototype
• Some types of testing, particularly reliability, require representative materials and construction
• Can you perform multiple tests on the same unit if you go from least to most destructive to
keep build quantities and costs low?
■ Build your schedule so that test results from one prototype inform the next
generation prototype
• Don’t ignore ambiguous or negative test results and charge ahead!
TEST & VALIDATION
9 | S Y N A P S E C ON F I N D E N T I AL
12. Ask for help at key decision points
■ Once you have a prototyping plan, have a plan review
• Did you choose an effective, efficient approach based on the challenges you anticipate
and who you’re trying to impress?
• Are there major design or technology risks that your prototype doesn’t mitigate?
• Have you chosen appropriate materials, processes, and components?
■ Before releasing custom PCBs or tooling, have a detailed technical review
• Custom parts are expensive and have long lead times
• It’s easy to make silly mistakes
■ Part on PCB has wrong package size or pinout
■ Incorrect connector orientation
■ Overconstrained component interfaces
■ Once you’ve processed the test data, have a results review
• If your results are ambiguous, or if there are multiple paths forward, this is a good time to
consult an expert on go-forward strategy
