Welcome to my site!
After graduating in Computing in 1990, I accepted a position as a programmer at a Runcorn based software house specialising in electronic banking software, namely sp/ARCHITECT-BANK on Tandem Computers (now HPE NonStop). This was before the internet became more prevalent and so the notion of enabling desktop access to company accounts for inter-account transfers and book keeping was still quite a cutting edge idea (and smartphones only ever hinted at in Space 1999). The company was called The Software Partnership (which was taken over by Deluxe Data in 1994).
I spent 5 years in Runcorn developing code for SP/ARCHITECT for various banks like TSB, Bank of Scotland, Rabobank and Girofon (Denmark) to name but a few. I then moved onto a software house in Salford Quays for further bank facing projects. After a further 23 years in the IT industry and now a Senior IT Project Manager (both Agile and Waterfall delivery), I thought I would echo out my Career Profile in this corner of the internet for quick and easy access.
SAFe (Scaled Agile Framework) events are structured, time-boxed ceremonies designed to drive synchronization, alignment, and continuous improvement across different levels of an enterprise.
These events are primarily categorized into Team-level events (which mirror standard Scrum practices) and Agile Release Train (ART) level events (which orchestrate multiple teams working toward a shared goal).
The core events within Essential SAFe are broken down below by organizational layer.
👥 Agile Team-Level Events
These recurrent ceremonies occur inside a short timebox called an Iteration (typically lasting 2 weeks) and focus on local execution.
Iteration Planning: Teams refine the iteration plan, select backlog stories, and commit to a set of Iteration Goals.
Team Sync (Daily Stand-up): A brief, daily 15-minute meeting where team members align on progress, discuss daily goals, and highlight impediments.
Iteration Review: A cadence-based showcase at the end of the iteration where teams demo working software to gather immediate feedback.
Iteration Retrospective: Held at the end of each iteration to reflect on the process, team dynamics, and behaviors to drive relentless improvement.
Backlog Refinement: A weekly meeting where the Product Owner and team flesh out, estimate, and prep user stories for upcoming iterations.
🚊 Agile Release Train (ART) Level Events
These higher-level events drive the Planning Interval (PI), an 8 to 12-week timebox where an entire “train” of 5–12 teams delivers cross-functional value.
PI Planning: The multi-day flagship event of SAFe where all teams, stakeholders, and leaders align on a shared business vision, map dependencies, and commit to PI objectives.
System Demo: A regular event occurring every iteration where the integrated functionality built by the entire ART is demonstrated to stakeholders for feedback.
Coach Sync (formerly Scrum of Scrums): Facilitated by the Release Train Engineer (RTE), Scrum Masters meet to resolve cross-team dependencies, risks, and progress hurdles.
PO Sync: Product Owners and Product Management meet to track milestone progress, manage scope adjustments, and ensure the train remains aligned with business goals.
ART Sync: A combined session of Coach Sync and PO Sync used to streamline communication regarding execution and deployment.
Inspect & Adapt (I&A): A major event held at the end of the PI consisting of a system demo, quantitative measurements, and a problem-solving workshop to implement systemic backlog improvements.
Summary of Differences
For a quick comparison, you can look at how responsibilities scale across the framework:

ActionView.400 is an enterprise tracking and diagnostics software solution developed by Insider Technologies Limited. It was purpose-built as a dedicated monitoring tool for the Open System Interconnection / Message Handling System (OSI/MHS) X.400 subsystem deployed on Tandem, Compaq, HP, and HPE NonStop server platforms.
The software acts as a critical infrastructure layer used heavily by banking institutions, telecommunications providers, and government/military defense sectors.
It ensures that high-volume, secure electronic mail infrastructure meets strict Service Level Agreements (SLAs) by allowing engineers to account for every message, calculate end-to-end processing times, and issue real-time tracking metrics.
Detailed Timeline Breakdown by Year
1989: Insider Technologies Limited is incorporated in Manchester, England, by a collective of IT industry veterans. The firm initially focuses on building service management and custom tracking middleware for the rapidly expanding Tandem NonStop server ecosystem.
1990s (Early to Mid): As X.400 protocols become the global standard for secure EDI (Electronic Data Interchange) and military messaging, Insider Technologies develops ActionView 400. The product is integrated directly into Tandem’s core software stack and begins shipping natively with Tandem NonStop platforms.
1997: Tandem Computers is acquired by Compaq. ActionView 400 is sustained through this transition to maintain critical operations for tier-one banks and national military infrastructures relying on NonStop systems.
2002: Compaq merges with Hewlett-Packard (HP). ActionView 400 is bundled under the HP NonStop software catalog (product designation T8443), managing and diagnosing log audits like the AUDLOG framework.
2000s (Mid to Late): Insider Technologies starts shifting forward-looking tracking requirements toward its newer central architecture platform, Sentra. While ActionView 400 continues handling legacy X.400 pipelines, Sentra begins acting as a unified web console to consolidate both X.400 and modern SMTP/MIME email flows across multi-vendor systems.
2015: HP splits its corporate structures. The NonStop computing line and the management of ActionView 400 shift over to Hewlett Packard Enterprise (HPE).
2018: In December 2018, HPE officially moves ActionView 400 to Obsolete status, marking the formal end of its product life cycle and standard vendor service life.
2019 – Present: Despite official obsolescence on the HPE hardware list, Insider Technologies continues to directly support and maintain the solution for deep-legacy military, defense, and governmental bodies. Because these sectors still mandate uncompromised, zero-loss X.400 message accounting, the software remains active, feeding tracking telemetry directly into Insider’s modern Middleware Monitoring and Sentra platform interfaces.

Completing the Stakeholder List using Process Analysis
Completing a stakeholder list using process analysis involves tracing the end-to-end lifecycle of a process to identify every individual, team, or organization that interacts with, influences, or is impacted by it. This ensures no hidden users, bottlenecks, or approvers are missed.
A four-step approach will ensure your list is thorough and actionable:
1. Map the Process Flow
Create a step-by-step flowchart of the current or future process. Break it down into key phases: Inputs, Activities, Outputs, and Outcomes. This visual map acts as a blueprint to spot every touchpoint where someone is involved.
2. Identify Stakeholders at Each Touchpoint
Go through each phase of your process map and ask the following dependency questions to pinpoint roles:
Input Stage: Who supplies the data, materials, or funding? (e.g., vendors, regulators, finance departments)
Activity Stage: Who performs the work or oversees it? (e.g., project teams, department managers, QA testers)
Output Stage: Who receives the final deliverable? (e.g., end-users, clients, customers)
Outcome Stage: Who is affected by the long-term results? (e.g., the community, executives, maintenance teams)
3. Classify and Prioritize
Once your comprehensive list is built, categorize stakeholders using the Power/Interest Matrix. This helps allocate your engagement efforts efficiently:
High Power, High Interest: Manage closely and collaborate heavily (e.g., Project Sponsors, Product Owners).
High Power, Low Interest: Keep satisfied but do not over-communicate (e.g., Regulators, Steering Committees).
Low Power, High Interest: Keep informed and consult regularly (e.g., End-users, Support Staff).
