- 2. Let’s begin with a story A tale about a failed software project
- 3. Once upon a time, a softwareproject began… “The client has a budget and wants the software fast.” “Quality is expensive, there’s not enough budget for it.” “Let’s just get this functionality working.” “The client needs to software urgently, we can’t wait.” “Let’s higher the juniors, we’ve got limited budget and need many pairs of hands.” “Clean code? Who cares about code? That’s just in books, it doesn’t really work in the real world…” “We don’t want to waste time on automated testing, let’s just do development.” “This is just a simple CRUD application, it’s really easy to implement and it shouldn’t take much time.” “As long as it looks good, that’s all that matters – after all, no one sees what’s in the background.” “Risk management? That’s just for the pessimists, this is a really simple project, what could possibly go wrong?”
- 4. And then,a few months into the project… “There’s too many bugs, let’s just hope it works for the demo” “We’re running out of time! Solve this bug and deploy the hotfix!” “We’re behind schedule, so we need to speed up.” “Why is it taking so long? These are really simple functionalities, why is it taking so long to implement simple changes?” “There’s a really important meeting coming up – with the big bosses – and if we don’t fix these bugs, it will be really embarrassing” “Why aren’t the developers working fast enough? We’ve got so many pairs of hands, why is the progress so slow?” “Our key developer has left – he knows all the nitty gritty details, how will the team cope?” “Take a deep breath, remember stress management and keeping calm under pressure – I’m sure we’ll somehow solve this, just like the projects in the past”
- 5. And finally, the projectending… “It’s finished, over budget, really late, and with so many open bugs” “Let’s do the routine lessons learnt meeting – but there isn’t really nothing to learn, we’ve known all along that you can’t have both quality and speed” “At least this project has finished, but surely the next one will be better” “… But then again, everyone knows this is the reality of software development projects, it’s the way it’s always been and there’s nothing we can do about it” “Quality and speed – as the golden saying goes – we can’t have both”

- 8. Optivem Framework Motivation Optivem Framework was motivated by the pains faced in the software development industry, esp. the quality vs speed trade-off Traditionally, developing high quality software required much higher up-front effort, in terms of designing architecture, setting up code standards, writing re-usable code, adhering to best practices etc. This was often in conflict with time / budget / resource limitations – and in those situations, these “pragmatic” factors had higher priority, leading to compromises in software quality
- 9. Optivem Framework Motivation To solve the challenges faced in software development (quality vs speed tradeoff), the Optivem Framework was designed to provide you with a high quality out-of-the-box architecture, ready made for needs of enterprise software, helping you build software with quality right from the start But at the same time, Optivem Framework is designed to increase developer team productivity and reduce the total development time, reducing both the time for architecture as well as ongoing development, providing default and base implementations to reduce amount of boilerplate code, yet at the same time providing extensibility for custom implementations To summarize, Optivem Framework empowers you to build high quality software fast
- 12. Optivem Framework Architecture II Clean architecture. Out-of- the-box system. Enterprise modelling. Supporting customer requirements. Automated testing. In-built quality processes. • Clean Architecture • Hexagonal Architecture • Onion Architecture • Domain Driven Design (DDD) • Use Case Driven Design • Test Driven Development (TDD) • Acceptance Test Driven Development (ATDD)

- 18. Optivem Framework Extensibility Plug & play extensibility Default implementation Custom implementation
- 19. Optivem Framework Extensibility II Plug & play extensibility Every component is replaceable and extensible You have flexibility and freedom both now and in the future Default implementation Provides you with default implementation using common libraries Use these default components for 80%* of your common needs Custom implementation Allows you to implement fully custom components Useful in those 20%* of situations when you have really custom needs * An approximation using the Pareto principle
