Lesson 63 - Prescriptive Strategy of Enterprise Architecture
Summary
TLDRIn this episode of 'Software Architecture Monday', Mark Richards explores the prescriptive strategy of enterprise architecture. He explains how this centralized approach mandates the use of common standards across the organization, reducing complexity and decision time. While this strategy offers cost-effectiveness and reusable assets, it can also lead to dissatisfaction due to its rigidity and the challenge of gaining enterprise-wide consensus. Richards also highlights the need for strong governance to prevent subversive projects. The episode invites viewers to consider the trade-offs of the prescriptive strategy in the broader context of enterprise architecture.
Takeaways
- 🏛️ The prescriptive strategy in enterprise architecture is a classic approach that dictates how solutions are developed using common standards across the organization.
- 🛠️ It involves a central governing body of enterprise architects who define a set of standards that every business unit and team must adhere to, such as specific technologies and methodologies.
- 🔍 The prescriptive approach aims to reduce complexity and decision-making time by providing predefined standards for all units, promoting consistency and reusability of assets like security frameworks and documentation techniques.
- 💰 One of the main advantages of the prescriptive strategy is cost-effectiveness, as it minimizes the need for individual units to develop their own standards and allows for the reuse of assets across the enterprise.
- 🚫 However, the strategy may not fit every purpose, as the central team's standards may not be suitable for every business unit, potentially leading to dissatisfaction and a lack of flexibility.
- 🤔 The strategy requires strong governance to prevent 'rebel camps' and ensure adherence to the defined standards, which can be challenging and may lead to resistance within the organization.
- 🔄 The centralization of standards can slow down the pace of innovation and the deployment of new projects, as teams must conform to the established infrastructure and technology choices.
- 👥 The enterprise architects enforcing the prescriptive strategy may become unpopular within the company, as they are responsible for imposing restrictions on technology and process choices.
- 📚 The script suggests considering both the pros and cons of the prescriptive strategy, acknowledging that while it has benefits, it also has significant drawbacks that need to be carefully weighed.
- 🔗 For further exploration, the speaker refers to lesson 62 for an introduction to enterprise architecture strategies and upcoming lessons for a deeper dive into other strategies and their applications.
- 🗣️ The speaker, Mark Richards, offers additional resources including private training classes, public speaking engagements, and online training through his website for those interested in learning more about software architecture.
