The article discusses a building in London which was constructed following the destruction caused by Boudica’s revolt against Roman rule. The revolt was triggered when the Roman Emperor Nero ignored the will of Prasutagus, a Celtic king who had left his kingdom to be shared between his daughters and Nero upon his death. Instead, Romans took over the area, leading to the uprising by Boudica. The building mentioned is thus part of the “re-beginnings” of the city after this significant historical event.

10. Product Development Processes You Might Not Have Heard of (2022)
Total comment counts : 10
Summary
The article by Richard Holmes discusses alternatives to traditional project management methodologies like Scrum, focusing on two innovative approaches:
ShapeUp:
- Shaping: This phase involves designers, engineers, and product managers exploring potential solutions before committing to development. It emphasizes rough, not perfect, designs and setting boundaries on what features will be included or excluded.
- Betting Table: Instead of maintaining a backlog, teams pitch ideas which are then “bet” on by stakeholders for investment. This method avoids the issue of endless backlogs by making immediate decisions on what to build.
- Building: The development cycle lasts for 6 weeks, aiming to create fully functional, integrated features rather than partial functionalities that require later iterations.
ShapeUp is designed to allow for deeper work and more meaningful product development, avoiding the rush often seen in shorter sprint cycles.
Plan, Build, Ship:
- This methodology, inspired by but lighter than traditional Waterfall, involves:
- Plan: Outlining the feature or project scope.
- Build: Developing the feature.
- Ship: Releasing the feature to the market.
- It’s a streamlined version of waterfall where each feature is managed from conception to delivery by a small team or individual, aiming for quick turnaround times.
- This methodology, inspired by but lighter than traditional Waterfall, involves:
The article highlights that while methodologies like Scrum are effective in certain environments, startups or teams needing more flexibility might benefit from these alternative approaches which allow for different paces and methods of product development. These methods are gaining traction among modern product teams looking for more adaptive or thorough development processes.
