Author: Mark Whitfield

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.

Higher National Diploma HND detailed timeline from introduction

The Higher National Diploma (HND) is a cornerstone of the British vocational education system. Introduced over a century ago to address gaps in industrial and technical training, it has evolved into a globally recognized Level 5 qualification equivalent to the first two years of a bachelor’s degree.

📅 The Comprehensive Timeline of the HND

🏭 1920s: Origins and the Industrial Revolution Response

  • 1920: The Higher National Diploma (HND) and Ordinary National Diploma (OND) were first introduced in England and Wales. They were created on an industry-by-industry basis to fix perceived inadequacies in traditional “Science and Art” technical exams.
  • 1921–1923: Initial subject frameworks were established. Mechanical Engineering launched in 1921, followed by Electrical Engineering in 1923, setting a trend for heavy technical specialization.

🏗️ 1930s–1950s: Expansion and Post-War Reorganization

  • 1929–1939: The qualification expanded rapidly to support the growing industrial economy, adding Building (1929) and Commerce (1939).
  • 1944: The Butler Act reorganized secondary and further education in the UK. HNDs remained the primary route for advanced, hands-on technical training within local colleges.

💼 1960s–1970s: The Shift to Business and Standardized Awarding

  • Early 1960s: Recognizing a shifting economy, Business Studies was introduced to replace older, outdated commerce frameworks.
  • 1974: The UK government established the Technician Education Council (TEC) and the Business Education Council (BEC) to standardize vocational curriculums. These bodies took over validation of HNDs to ensure national quality.

🎓 1980s–1990s: The BTEC Era and Globalization

  • 1983: BEC and TEC merged to form the Business & Technology Education Council (BTEC). From this point on, HNDs became widely known as “BTEC HNDs.”
  • 1996: BTEC merged with the University of London Examinations and Assessment Council to form Edexcel, scaling the qualification globally.

🌍 2000s–2010s: Pearson Takeover and International Adoption

  • 2002: The HND model was adopted internationally by other countries. For instance, Cameroon officially introduced the HND into its professional university pipeline by ministerial order.
  • 2003–2005: Global education giant Pearson fully acquired Edexcel.
  • 2015: HNDs were officially mapped to Level 5 on the UK’s Regulated Qualifications Framework (RQF), formally certifying them as equivalent to a Foundation Degree or the second year of a Bachelor’s degree.

🚀 2020s–Present: Modernization and Academic “Top-Ups”

  • 2020s: Pearson modernized HND frameworks into “Higher Nationals,” optimizing them for remote learning, portfolio assessments, and direct workplace entry.
  • Today: The HND is taught across more than 60 countries. It serves as a popular flexible option, allowing students to either enter the workforce immediately or pursue a one-year university “top-up” program to graduate with a full Bachelor’s Honours Degree in just three years total.

Mark Whitfield’s PROject Templates

Mark Whitfield’s PROject Templates are widely regarded as a high-quality, practical toolkit for IT and project management professionals. Instead of generic, academic frameworks, his resources are built from over 24 years of real-world delivery experience managing multimillion-pound projects for blue-chip companies like Capgemini, Lloyds Banking Group, and Royal Mail.

The primary selling point of the package is that it bridges the gap between traditional structured governance (Waterfall, PRINCE2) and modern iterative execution (Agile Scrum).

Here is a breakdown of what makes them well-regarded and a few things to consider:

✅ Why They Are Considered Good

  • Massive, Comprehensive Bundle: The toolkit includes a downloadable ZIP file containing over 200 fully editable templates. This spans Microsoft Project (.mpp) plans, Excel dashboards, Word documents, and over 35 PowerPoint variations for stakeholder reporting.
  • Designed for “What Actually Works”: The tools are modeled after actual client-facing delivery rather than theoretical textbook guidelines. They cover essential day-to-day artifacts like RAIDs logs (Risks, Actions, Issues, Dependencies), Plan on a Page (POaP) timelines, RACI matrices, and financial forecast trackers.
  • No Software Lock-in: For teams or clients who do not use complex software like Microsoft Project or Jira, the toolkit provides lightweight Excel equivalents—such as standalone Excel POaPs and manual Burn Down/Up charts.
  • Exceptional Value & Free Lifetime Upgrades: Purchased directly via the PROject Templates Platform, the complete bundle is frequently offered at a promotional rate of £38.00. Once you buy it, all future additions and version upgrades are free for life.

⚠️ What to Keep in Mind

  • Microsoft Office Ecosystem: The templates are heavily built around MS Excel, Project, PowerPoint, and Word. While they work across multiple devices and cloud platforms, you will get the most seamless experience if your organization relies natively on the Microsoft 365 ecosystem.
  • Hybrid Focus: If your team is strictly 100% pure Agile and manages absolutely everything natively inside Jira or Asana, some of the hybrid Waterfall/Agile governance templates might feel more thorough than you strictly need. However, they are incredibly useful if you have to report Agile progress to traditional C-suite executives.

RACI Matrix, Example Hybrid Project RACI

RACI Matrix Example Hybrid Project RACI
RACI Matrix – Example Hybrid Project RACI

A RACI matrix for a hybrid project bridges the gap between structured predictive governance (Waterfall) and flexible iterative delivery (Agile). Because hybrid projects mix distinct management styles, a RACI matrix is essential to clarify who owns high-level deliverables versus who manages sprint-level execution.

The Hybrid RACI Challenge

In pure Agile/Scrum, a RACI is often redundant because roles like Product Owner and Scrum Master have built-in accountability. However, in a hybrid environment, conflicts arise at the intersection points—such as when a traditional Project Manager interacts with a self-organizing Scrum Team, or when a cross-functional sprint output requires steering committee or regulatory sign-off.

The golden rule remains: Every task must have exactly one Accountable (A) owner to prevent costly decision delays.

  • R = Responsible (Does the work)
  • A = Accountable (Final decision maker/approver; only one per row)
  • C = Consulted (Two-way communication before the task)
  • I = Informed (One-way notification after completion)

Best Practices for Hybrid RACIs

  • Focus on Deliverables, Not Micro-tasks: Map out macro phases, key milestones, and critical cross-framework decision points rather than granular daily duties.
  • Delineate the PM and PO Roles: The Project Manager is typically Accountable for overall project timelines, budgets, and predictive governance. The Product Owner holds Accountability for product requirements, value delivery, and sprint goals.
  • Avoid Dual-Accountability Pitfalls: Never assign “A” to both the PM and the PO for the same item. If a task feels like it belongs to both, split it into separate lines (e.g., split “Product Deployment” into “Feature Validation” and “Release Governance”).
  • Keep the Sprints Agile: Do not write a RACI for inside a sprint. Trust the Scrum Guide for development cycles, and use the RACI strictly to manage how those cycles plug back into the larger corporate structure.

Infographic, Human Evolution to Homo Sapiens

Modern humans (Homo sapiens) emerged in Africa approximately 300,000 years ago after millions of years of gradual primate and hominin evolution.

Infographic, Human Evolution to Homo Sapiens
Infographic, Human Evolution to Homo Sapiens

Early Beginnings and Primate Roots

  • 85 million years ago (mya): Primates diverge from other mammalian groups during the Late Cretaceous period.
  • 55 mya: Earliest true primate fossils appear in the Paleocene epoch.
  • 15–20 mya: The ape superfamily diverges from gibbons and other primate lines, leading to early apes like Dryopithecus.
  • 6–7 million years ago (mya): The human lineage (hominins) splits from the ancestors of modern chimpanzees and bonobos in Africa. Sahelanthropus represents one of the earliest known species to begin walking upright (bipedalism).

The Rise of Australopithecines

  • 4–3 mya: Australopithecus species (such as Australopithecus afarensis) thrive in the grasslands of eastern and southern Africa. They walk fully on two legs but retain small, ape-like brain sizes.
  • 3.3 mya: Earliest known stone tool manufacturing begins in Kenya, predating the appearance of the modern human genus (Homo).

The Emergence of the Genus Homo

  • 2.8–2.5 mya: Homo habilis (the “handyman”) appears in Africa. They feature larger brains and systematically manufacture sharp stone flakes and core tools (Oldowan technology).
  • 1.9–1.8 mya: Homo erectus emerges with taller, modern-like body proportions (longer legs, shorter arms). They are the first hominins to migrate out of Africa into Eurasia, master controlled fire, and build basic shelters.

Transition to Modern Humans

  • 700,000–350,000 years ago (kya): Homo heidelbergensis spreads across Africa and Europe. They act as the common ancestral root that branches into Neanderthals in Eurasia and Homo sapiens in Africa.
  • 315,000 years ago: The oldest known anatomical remains of Homo sapiens (including skull fragments and a jawbone) are fossilized in Jebel Irhoud, Morocco. These early modern humans possess near-modern facial features alongside robust skeletal builds.
  • 50,000–40,000 years ago: The Upper Paleolithic revolution sees Homo sapiens develop advanced symbolic behavior, complex art, sophisticated blade toolkits, and widespread global expansion.
