 SAAS to SaS Models

A revolutionary new model that is enhancing the knowledge worker’s role

©Prof Archie D’Souza

Among the great defining characteristic of the AI/ML era is that software has become service-based. The transition of software into a service-based model is a significant shift in the way businesses operate. The need for efficiency, speed, and cost-effectiveness drive this change. Software now autonomously performs tasks. The Service-as-Software (SaS) model allows for delivery of outcomes rather than tools. This transformation has been facilitated by advancements in AI and automation. This enables software to interpret inputs, make decisions, and execute workflows. Does it mean that knowledge work by humans has become redundant?

See: https://medium.com/beyond-the-curve-innovation-leadership-insights/saas-to-sas-the-next-frontier-of-enterprise-value-d52eebd244f5

No. The rapid advances in Artificial Intelligence (AI) and Machine Learning (ML) do not make human knowledge work redundant. Rather, they redefine it. AI automates certain cognitive tasks, but in doing so it raises the value of uniquely human capabilities such as judgment, creativity, ethics, systems thinking, leadership, and wisdom. History suggests that every major technological revolution has increased, rather than diminished, the demand for higher-order human intelligence.

A useful way to understand this is to distinguish between information, knowledge, intelligence, and wisdom.

• Information is raw data.
• Knowledge is organized information.
• Intelligence is the ability to apply knowledge to solve problems.
• Wisdom is knowing what should be done, why it should be done, and when it should not be done.

AI excels at processing information and, increasingly, at organizing knowledge. It can even imitate aspects of intelligence by identifying patterns and generating plausible solutions. However, it does not possess wisdom, moral responsibility, accountability, or genuine understanding of human values. These remain human domains.

Every technological revolution has elevated human work

This has been my contention ever since I got first exposed to technology. History offers numerous examples. Let’s look at a few:

·        The Industrial Revolution mechanised physical labour, yet it created new professions in engineering, factory management, finance, logistics, marketing, and education.

·        Computers automated calculations that once occupied rooms full of clerks. Yet the computer age created software engineers, systems analysts, cybersecurity specialists, data scientists, project managers, and countless other knowledge-intensive occupations.

·        The Internet automated access to information but dramatically increased demand for professionals who could interpret, evaluate, and apply that information.

·        AI represents the next stage in this progression. Instead of replacing human intelligence, it automates routine cognitive work, allowing humans to focus on more complex intellectual activities.

AI removes routine thinking, not meaningful thinking

Knowledge work is often misunderstood as simply manipulating information. In reality, it involves several layers.

Routine tasks include:

• Searching for information
• Summarizing documents
• Drafting reports
• Generating code
• Translating languages
• Creating presentations

These are precisely the activities AI performs exceptionally well.

However, higher-order knowledge work involves:

• Defining the right problem
• Challenging assumptions
• Making decisions under uncertainty
• Reconciling conflicting stakeholder interests
• Exercising ethical judgment
• Negotiating trade-offs
• Inspiring people
• Leading organizational change

These activities require contextual understanding that extends far beyond statistical pattern recognition.

AI increases the premium on human intelligence

Ironically, the more capable AI becomes, the greater the importance of human intelligence.

Why?

Because AI produces options—not decisions.

For example, an AI system may generate ten possible business strategies. Someone must still determine:

• Which strategy aligns with organizational goals?
• What ethical implications exist?
• What risks are acceptable?
• Which stakeholders will support or resist the proposal?
• What unintended consequences may arise?

These questions require experience, judgment, and accountability.

Knowledge workers become intelligence amplifiers

The future knowledge worker is unlikely to compete with AI.

Instead, they will collaborate with it.

A project manager, for example, may ask AI to:

• Generate schedules
• Analyse project risks
• Draft stakeholder communications
• Summarize meeting discussions
• Forecast delays

The project manager's value increasingly lies in:

• Choosing among AI-generated alternatives
• Motivating diverse teams
• Resolving conflicts
• Managing ambiguity
• Building trust
• Taking responsibility for outcomes

The human evolves from information processor to intelligence orchestrator.

AI creates demand for deeper expertise

Paradoxically, AI makes domain expertise more valuable.

An inexperienced user may accept AI outputs uncritically.

An expert, however, can:

• Detect errors
• Recognize hallucinations
• Ask better questions
• Provide richer context
• Improve AI outputs through better prompting
• Validate recommendations

In other words,

The quality of AI output increasingly depends on the quality of human input.

Garbage prompts still produce garbage results.

Human intelligence becomes more multidisciplinary

AI handles narrow analytical tasks extremely well.

Humans, however, integrate knowledge across disciplines.

Consider a supply chain disruption.

AI can estimate inventory shortages.

A human leader must simultaneously consider:

• Customer relationships
• Political developments
• Environmental regulations
• Financial constraints
• Labour issues
• Corporate reputation
• Long-term strategy

This integration of multiple perspectives remains one of humanity's greatest strengths.

Creativity becomes more valuable, not less

AI recombines existing patterns remarkably well.

Human creativity often emerges from:

• Personal experience
• Emotional insight
• Cultural understanding
• Curiosity
• Serendipitous discovery
• Challenging accepted assumptions

Many breakthrough innovations occur precisely because someone questions conventional thinking rather than extrapolating from historical data.

AI cannot own responsibility

Perhaps the strongest argument for continuing human knowledge work is accountability.

When an AI recommends:

• approving a loan,
• diagnosing a patient,
• sentencing a criminal,
• launching a military operation, or
• investing billions of dollars,

someone must ultimately accept responsibility.

Organizations, governments, and societies cannot delegate accountability to algorithms.

Responsibility requires human judgment.

The future belongs to AI-driven humans, not AI alone

The emerging workforce will not be divided into "people versus AI."

Instead, it will increasingly be divided into:

• professionals who know how to work effectively with AI, and
• professionals who do not.

The first group will consistently outperform the second.

The competitive advantage therefore shifts from merely possessing knowledge to applying knowledge intelligently through AI-enabled collaboration.

Conclusion

The proposition that AI will make human knowledge work redundant rests on a narrow definition of knowledge work as information processing. In reality, the highest forms of knowledge work involve judgment, creativity, ethical reasoning, leadership, contextual understanding, and accountability—capabilities that AI supports but does not replace.

Rather than diminishing the importance of human intelligence, AI elevates it. As machines assume routine cognitive tasks, humans are freed to concentrate on those uniquely human capabilities that create lasting value. The future, therefore, is unlikely to belong to artificial intelligence alone; it will belong to augmented intelligence—where AI amplifies human capability, and human intelligence provides purpose, direction, wisdom, and responsibility.

For someone of your background in project management and your broader message that AI will not take away jobs but will change the nature of work, I would go one step further and summarize the argument in a single sentence:

AI does not reduce the need for human intelligence; it raises the minimum level of human intelligence required to create value.

I think that captures the central thesis succinctly and is a proposition you could build an article, lecture, or even a book chapter around.

 

Logistics in Ancient & Medieval India

An excerpt from my book AI, Blockchains and the Future of Project Management

©Prof Archie D’Souza

Commerce and communications did not start with rapid transport and communications. The term logistics, according to a copilot search and what every textbook will tell you, was first used by Napolean’s army. Here are some excerpts:

The word logistics originates from the French term logistique, derived from logis meaning lodgings, and was influenced by the Greek word logistikos, meaning skilled in calculating. The modern term logistics entered the English language in 1846, borrowed from the French logistique, which referred to the art of moving, quartering, and supplying troops. The French word itself comes from logis, meaning lodging or shelter, which traces back to Old French loge and ultimately to the Proto-Germanic root laubja, meaning shelter. This reflects the original military context, where logistics involved organizing accommodations and supplies for armies, according to this search.

See:  Etymonline+2 &  Etymonline

However, the French invented neither the term not the discipline of Logistics. There are terms in the Artha Shastra that can be translated into modern logistics and transportation terminology. While exploring this subject, I asked ChatGPT how the Artha Shastra would describe logistics in contemporary terms. The response provided a useful synthesis of the concepts, although its opening sentence was not entirely accurate. There is, in fact, a Sanskrit term corresponding to logistics, which I discuss later. The response is reproduced below as an interpretive summary rather than as a translation of the original text.

Quote  

The Artha Shastra does not use the modern term "logistics," but it contains one of the earliest systematic discussions of what we would today recognize as logistics, supply chain management, procurement, inventory management, transportation, infrastructure, and military sustainment.

The text views logistics as a function of statecraft. A kingdom's strength depended not merely on the size of its army, but on its ability to provision, move, and sustain people, goods, and information.

Here are some of the major logistics themes found in the Arthashastra.

1. Procurement and Supply Management

The king was expected to maintain continuous supplies of:

• food grains
• weapons
• metals
• timber
• textiles
• animals
• medicines
• fuel

Government officials supervised procurement, quality, storage, and distribution.

In modern terminology, this corresponds to:

• Strategic sourcing
• Procurement management
• Inventory planning
• Supplier management

---

2. Warehousing and Inventory

The Arthashastra recommends maintaining granaries and warehouses throughout the kingdom.

These served multiple purposes:

• famine preparedness
• military reserves
• price stabilization
• emergency relief

Inventories were carefully recorded and audited to prevent theft and spoilage.

Today we would call this:

• Warehouse management
• Safety stock
• Inventory control
• Risk mitigation

---

3. Transportation Infrastructure

The treatise emphasizes building and maintaining:

• roads
• bridges
• river crossings
• ports
• canals

Efficient transport was considered essential for:

• trade
• tax collection
• military movement
• administration

This closely resembles today's emphasis on logistics infrastructure.

---

4. Military Logistics

Perhaps the strongest logistics discussions occur in relation to warfare.

The text advises that armies should never march without adequate:

• food
• water
• pack animals
• medical supplies
• reserve equipment

Campaign routes were selected partly based on:

• availability of water
• forage
• terrain
• seasonal conditions

Modern military planners would recognize these as logistics planning considerations.

---

5. Supply Chain Security

The Arthashastra repeatedly warns against disruptions to supply.

Recommendations include:

• protecting trade routes
• securing warehouses
• guarding transport convoys
• preventing sabotage
• monitoring merchants

Supply continuity was treated as a national security issue.

---

6. Standardization and Quality Control

Government inspectors verified:

• weights
• measures
• product quality
• pricing
• authenticity

Counterfeit goods and adulteration attracted severe penalties.

Modern equivalents include:

• Quality assurance
• Compliance
• Supply chain governance

---

7. Information as a Logistics Asset

The treatise gives great importance to intelligence gathering.

Officials and spies reported on:

• road conditions
• market prices
• availability of supplies
• enemy stockpiles
• merchant activity

This resembles today's:

• supply chain visibility
• market intelligence
• logistics analytics

---

8. Risk Management

The Arthashastra recommends preparing for disruptions caused by:

• drought
• floods
• war
• epidemics
• crop failures

The state should diversify supplies and maintain reserves.

This aligns closely with modern business continuity and supply chain resilience.

---

9. Revenue and Trade Logistics

Trade was carefully regulated through:

• customs checkpoints
• ports
• toll stations
• warehouses
• trade inspectors

The objective was to encourage commerce while ensuring tax collection and preventing smuggling.

---

Comparison with Modern Logistics

Arthashastra	Modern Logistics
Royal granaries	Distribution centres
State warehouses	Warehousing
Caravan routes	Transportation networks
Superintendent of Commerce	Supply chain manager
Granary reserves	Safety stock
State auditors	Inventory auditors
Spies gathering market intelligence	Supply chain visibility systems
Military provisioning	Defence logistics
Trade checkpoints	Customs and border logistics
Seasonal planning	Demand forecasting

What Makes the Arthashastra Remarkable?

Written around the 4th century BCE (though parts may reflect earlier traditions), the Arthashastra presents an integrated view of governance in which economic administration, transportation, warehousing, taxation, commerce, intelligence, and military operations are interconnected. Rather than treating logistics as a purely operational concern, it recognizes that a state's stability and prosperity depend on the continuous, secure, and efficient movement of resources.

Given your background in logistics and project management, there is an interesting parallel for your work: the Arthashastra effectively anticipates the modern idea that logistics is a strategic capability, not merely an operational function. Its emphasis on reserves, infrastructure, information flows, and risk management aligns closely with contemporary concepts of supply chain resilience and enterprise risk management, making it a compelling historical reference in discussions of AI-enabled and blockchain-enabled logistics.

We will come back to the discussion on the French origin of the term later. I went back to ChatGPT mentioning how logistics was conducted in ancient and medieval India and their answer was in these lines. But, these are my own words now. The Artha Shastra reflects a sophisticated administrative system rather than isolated references to trade. From ancient times, India had a network of roads and resthouses called dak banglas. This is what copilot says. Dak Bangla refers to a rest house or guest house originally built for postal service travellers and he term Dak means mail or postal service in the Indian subcontinent. Yes, India had a postal service long before the British introduction of the Penny Post. Historically, mail in India was delivered through a relay system of runners or horse riders. Bangla refers to a bungalow or single-story house, of course, this word has been adopted in English from the Hindi word. Therefore, Dak Bangla literally translates to postal bungalow or a house associated.

See:  UpToWord

The British continued these services during their occupation of India. More dak banglas were constructed along major routes to provide rest and accommodation for postal couriers, government officials, and travellers. They served as relay points for the dak (mail) system, ensuring efficient communication across long distances. These buildings were often simple, functional structures, strategically located near roads or administrative centres. They continue to exist today. Currently, dak banglas are generally used as government guest houses for officials or tourists. Some have been preserved as heritage buildings, while others continue to function as lodging facilities under state or central government management. The term is still widely recognized in India, Bangladesh, and Nepal as a symbol of the glory days of India the pre-colonial-era. This was great infrastructure for travel and communication. So, as we see, the concept of relay stations and rest houses is ancient, as is the term dak bungalow. Dak (डाक) today means post or mail in Hindi and several other Indian languages. The word is generally traced through Indo-Aryan usage and became firmly associated with the postal system. Bungalow comes from बंगला i.e., bangla, and the compound dak bungalow became common and continues to be so. The word dak, meaning post or mail, reflects the long-standing importance of communication networks in the Indian subcontinent.

The Artha Shastra also mentions several administrative titles. This is perhaps among the most fascinating aspects of the Artha Shastra. Readers may be surprised to discover that it describes officials whose responsibilities closely resemble those of modern logistics professionals. Here are some terms that you will encounter corresponding to the following:

• Superintendent of Ships or Shipping (maritime administration)
• Port administrator or harbour superintendent
• Customs officer responsible for duties and tariffs
• Superintendent of Commerce
• Superintendent of Storehouses
• Superintendent of Weights and Measures
• Superintendent of Armouries
• Superintendent of Mines and Metals
• Officers responsible for roads, ferries, and transport

It is clear that taken together, we have demonstrated that the Artha Shastra viewed the movement of goods, people, information, and revenue as an integrated administrative system. There was also a unified system of international trade regulations that many millennia ago. We would, in modern language, recognise this as a combination of logistics, supply chain management, transportation management, customs administration, infrastructure management, and commercial regulation.

I am not yet claiming that ancient India invented logistics in the modern sense. That is a hypothesis that needs to be researched, maybe a topic for a future book or paper. But, I repeat, this does demonstrate that many oLogistics in Ancient & Medieval India

That is a defensible historical position and one that I hope logistics scholars are likely to appreciate. Let us come back to the etymology of the modern term. I do intend to start work soon on a treatise on India’s maritime history. I wish to prove there that, considering the tools that were available then, we had a very sophisticated code or perhaps a set of codes to regulate domestic and international commerce, a code that the British destroyed.

My Tryst with Technology

A Journey from Mainframes to AI – Part One

©Archie D’Souza

Three years ago, when my book Simplifying Blockchain Complexities was released, I knew that AI, ML & IoT would play a big role in supply chains. I knew it when I started researching for the book. It has indeed done so, and hence I felt the need for a second edition. This will be released soon. However, as I began my research, I came to the conclusion this book, while needing a second edition, a separate book on the applications of AI in tandem with blockchains in projects and supply chains was also the need of the day. Hence, this book.

The applications of Blockchain Technology outside cryptocurrency trading was in its infancy. No logistics player was keen on even looking at its use in supply chains. And, almost nobody looked at it beyond its application as a distributed ledger used to record Bitcoin transactions. But, we realised, and there were others also discovering that the technology has applications beyond cryptocurrencies. Since the release of the first edition, there have been several developments and disruptions in the fields of Supply Chain and Project Management. AI, ML and IoT are taking over at an unimaginable pace. The disruptions brought about by Russia’s invasion of Ukraine and the US/Israeli strikes on Arab territories have caused most countries to rethink their supply chain. These disruptions will need tweaking in the way payments are made and new laws will need to be enacted to reflect the new realities.   

I am today recognised as a Supply Chain & Project Management Expert, an educator, an International Logistics Strategist and a Private International Law Specialist. I’ve been serving global trade since 1978. My first corporate assignment was with the cargo division of Air India in Bombay, as the city of my birth was then known. But my professional journey as a logistician started even before that. Since my parents could afford to pay for my college education, I had to work and study. The first job I took up was during the SSC exams at our school. I served water to the candidates, being paid five rupees fifty paise per day. A year later, I passed my SSCE, and we had a three-month gap between the last day of exams and the college's first term. I filled air in a petrol pump and earned enough to pay through my first year of college. Later, in my first year of college, I joined a company whose office was very close to college. This was my introduction to logistics. I’ll come to that later.

 

 

Transportation has fascinated me from a very young age. Since I can remember, anything that moved appealed to me – scooters, bikes, cars, trucks, busses, trains and planes. I was also fascinated with anything electronic like, music systems, TVs, the Walkman and computers. When I was in college, we were still in the mainframe era. The top two companies of that era were IBM and Burroughs. Let’s look at these eras before we come to the AI era.

1.     The Mainframe Era (1950s–1970s) - the Age of Centralized Computing

The fifties, sixties, and seventies together saw the era of mainframes. Banks, insurance companies, airlines, universities, school examination boards, and public utilities all saw computerised statements and prints. By today’s standards, these looked crude and were noisy. However, they were a great step forward from manual operations. The computer systems needed a great deal of floor space. If one looked at companies like Air India, the Shipping Corporation of India, LIC, State Bank of India, and others, which occupied the newly built skyscrapers of Nariman Point, their systems occupied full floors of buildings, each floor being thousands of square feet in area. The memory that these systems had was less than the memory in the laptop on which I’m feeding this text.

But the computer had started, and before long, we saw the introduction of user-friendly personal computers. But there was something in-between.

Defining Characteristics

• Massive centralized computers
• Batch processing using punch cards
• Computing accessible only to governments, banks, universities, and large corporations
• Users submitted jobs and waited hours—or days—for output

Important Milestones

• 1951: IBM introduces early commercial computers
• 1964: IBM System/360 revolutionizes enterprise computing
• COBOL and FORTRAN become dominant programming languages

Human Experience

This was the era when computing was mysterious, expensive, and elite.
Engineers and operators were custodians of a rare resource.

My Personal Experience

• First exposure to data centres and training institutions like NIIT and Datamatics
• Punch cards or terminal systems
• The culture of discipline and precision around computing
• The need for huge floor spaces with temperature control.

Then came the era of the mini-computers

---

2.     The Minicomputer Revolution (1970s) – Computing Moves Closer to Businesses

The introduction of the minicomputer was a foregone thing as mainframes required specialized rooms and technicians for operation. The user was thus separated from the computer. The mini changed that. It was designed for direct, personal interaction with the programmer. Mainframes operated in isolation; minis could communicate with other systems in real time. In contrast with much larger mainframe memories needed for scientific calculations and business records, the first minis stored only 4,096 words of 12- or 16-bit. Unlike larger computers featuring expensive input/output devices, early minis used only a Teletype or a Flexowriter and a paper-tape punch/reader. Minis were designed for process control, data transmission, and switching. Mainframes, on the other hand, emphasized data storage, processing, and calculating. Minicomputers that did the most to define the new class of computers were sold to original equipment manufacturers (OEMs) that incorporated minis into larger control systems, often for industrial processes.

 

Defining Characteristics of Minis

• Smaller and more affordable than mainframes
• Department-level computing emerges
• Interactive terminals become common

Important Milestones

• Digital Equipment Corporation popularized minicomputers
• UNIX operating system gains traction
• Time-sharing systems emerge

Industry Impact

Computing starts becoming operational rather than purely administrative.

What followed

• Transition from centralized control to departmental access
• Early systems programming or enterprise applications

The next episode will be on the commencement of my corporate journey and my first tryst with mainframe computers. Do watch this space.
