If you\u2019re involved in design (and even if you\u2019re not) you probably know about the Double Diamond process. But, is that the end of the story? This article expands the perspective and completes the model by taking you from ambition to market in a repeatable entrepreneurial cycle.<\/p>\n

Divergence and convergence<\/h2>\n

Back in 1996, Hungarian-American linguist B\u00e9la H. B\u00e1n\u00e1thy made obvious something that was hiding in plain sight, and as a linguist he expressed it in beautifully simple terms. He described the thinking process in terms of two key phases, the first being divergence and the second convergence. During divergence we consider a situation and create a range of choices arising from that situation. Convergence then follows and we narrow those choices down to a single decision point.<\/p>\n

For example, you\u2019ve bought a new painting for your home, and now it needs to be displayed. Maybe you already have a space for it, but more likely, you now examine your rooms and build up in your mind a list of places where it would look great. This is divergence.<\/p>\n

Next, you imagine the painting in each of these places. Perhaps you get a friend or partner to hold it up so that you can get a feel for how it\u2019ll look. Slowly you narrow down the field of options until you’re left with just one – the perfect spot. This is convergence.<\/p>\n

Divergence involves expanding your understanding and increasing your options without judgement. To judge and reject too early is to do so without adequate knowledge. Far too many great ideas end up on the cutting room floor (or voted down in \u201cbrainstorming\u201d sessions) because they\u2019re unfamiliar or poorly understood. This is why divergence has to be allowed to happen before any attempt is made at convergence.<\/p>\n

Convergence is reduction of options through elimination, and most importantly elimination through experimentation rather than through opinion or \u201cgut feel\u201d. You\u2019d be amazed at just how many \u201cobvious\u201d things turn out to be wrong when put to the test in the real world. For example, we all know that warm water freezes faster than cold water, don\u2019t we. That\u2019s so obvious we really don\u2019t need to waste time testing it? It\u2019s a safe assumption, right? If you agree, I recommend you read up on the Mpemba Effect<\/a> – a timely reminder that there is no such thing as a safe assumption.<\/p>\n

A tale of two diamonds<\/h2>\n

Divergence followed by convergence can be pictured as a diamond, starting from a single decision point, and expanding out like a tree, growing freely. Once the tree is fully grown its branches are then pruned back until only the strongest remains. This is your new decision point from which you grow your next tree.<\/p>\n

You can apply this pattern to most situations that require thought and an outcome. Choosing a holiday; picking a route to work; designing a new mode of transport; even painting that picture. In just two words, B\u00e9la brought to life the idea that problem solving was not a linear process that created certainty out of chaos, but instead a journey that created chaos in order to get to the next point of certainty.<\/p>\n

This is a concept that appeals to the creative mindset, and so it comes as no surprise that the British Design Council took this concept and popularised it in the form of the Double Diamond design process model.<\/p>\n

As the name suggests, the model sees the design process as two consecutive divergence-convergence activities, the first consisting of discover and define, and the second of develop and deliver. The first phase allows you to discover a problem domain to gain insight, and then narrow down that insight to define the problem to be solved. The second uses that problem definition to develop a range of potential solutions, tested for viability, and then deliver these solutions to an audience and use their feedback to converge on a single preferred solution.<\/p>\n

The double diamond model has become almost ubiquitous in the world of design, and there may well be as many renderings of the illustration above as there are designers. However, as I mentioned earlier, the divergence-convergence model can be applied to most situations requiring thought and therefore to most meaningful undertakings. It was only a matter of time before the Double Diamond concept was extended.<\/p>\n

Two\u2019s company, three\u2019s a crowd<\/h2>\n

It\u2019s at this point in our story that the Triple Diamond Model enters the fray. There are many versions of this model and they all vary in the terminology used, but the one thing the majority have in common is the direction in which they extend the model. The new diamond is placed in front of the Double Diamond model and its two stages are often referred to as \u201copportunity\u201d and \u201cstrategy\u201d.<\/p>\n

The intention of this extra diamond is to reflect the process that gets us to the awareness that there is a particular problem worth solving. First explore the market to find a range of opportunities (divergence), then formulate a strategy that targets the first of these opportunities in the form of a proposition (convergence). In the world of software development, this is where the product strategy emerges.<\/p>\n

Some would say this is just taking a good model and ruining it with unnecessary embellishment. It\u2019s a common pattern with models that people spend too little time understanding them before adding complexity to cover aspects already encompassed by the original concept. A minimalist’s nightmare.<\/p>\n

Others would suggest that the Double Diamond is specific to one particular viewpoint, and requires extension to cover a broader range of perspectives. I\u2019m an advocate for the second view – the double diamond is an excellent start, but it\u2019s not the full story. The real question is how far does that story stretch? Is three diamonds enough? Four? Is there even a limit?<\/p>\n

For those of you who hate spoilers, look away now. For the rest of you, (the impatient ones), the answer is five.<\/p>\n

A matter of perspective<\/h2>\n

To understand the Double Diamond we have to see it in context, and to do this we need to expand our perspective to encompass the full process from start to finish. Designers often (rightly) complain that they are not engaged early enough in the process, and this in itself is a recognition that there is a broader activity to which they could contribute. The same is true for most participants in the creative process. Each sees the process from the perspective of when they are first approached to the point where their role ends. Beyond those points things become more vague and tend to get condensed into \u201cthe step before\u201d and \u201cthe step after\u201d. What might, from a local perspective, seem like brief steps, are actually a chain of events spanning weeks or even months of investigation and insight.<\/p>\n

Also, when considering processes, it is popular to think in terms of straight lines and trends (a beginning, a middle and an end; a start point and a destination). However, many things in life are cyclic, and only look like linear trends if we observe them for a limited duration. Proper understanding requires context. The context for the Double Diamond process is product development, and this is part of a loop I like to refer to as the \u201cEntrepreneurial Cycle\u201d.<\/p>\n

As can be seen, this cycle involves five points of focus, and it is from this that the limit of five diamonds is derived. To get from one point to another requires divergence to understand and create options followed by convergence to get to the decision point. But first a quick summary of how the cycle operates.<\/p>\n

An entrepreneur operating in a given market observes that market and perceives threats and opportunities emerging as that market evolves. This observation gives rise to an ambition and ambition leads to the development of a range of strategies from which one is chosen. This strategy gives rise to a proposition which in turn is developed into a product that can be deployed into the market. If this product is successful, it will inevitably change the market, leading to new threats and opportunities, and so the cycle repeats itself.<\/p>\n

The biggest lesson to draw from this is not just that product development is a cycle, but that the act of developing products feeds the cycle and keeps it going. The very act of introducing a new product into the market changes that market, and so a wise entrepreneur recognises the need to keep moving. In essence, the market for which your product was developed no longer exists once your product is successful.<\/p>\n

Turning the wheel<\/h2>\n

Let\u2019s take a simple example to bring the Entrepreneurial Cycle to life. A company providing an online service has seen a plethora of challengers enter their market. Customer churn is high and brand loyalty is low. Although they\u2019re seeing as much customer gain as loss (and thus maintaining market share), the cost of maintaining this share is becoming uneconomical.<\/p>\n

They believe their service is superior and embark on a venture to radically improve customer retention and brand loyalty. They have established their ambition.<\/p>\n

They also observe other apparently similar industries adopting subscription models and believe this might be a way to achieve this retention. This approach now forms the basis of their strategy.<\/p>\n

The information available to them shows that a monthly subscription model providing customers great value for money through unlimited access to services has improved retention in other industry sectors. They also believe that by adding benefits and exclusive rewards to this model they will achieve the levels of customer retention they desire. Their proposition is starting to take shape.<\/p>\n

They now look into their customer base and decide a single subscription won\u2019t work for everyone, so they define a tiered model and develop this into a set of subscriptions options from which the customer can choose (silver, gold and platinum). Each has a different level of service and associated offers, and comes with different levels of customer support ranging from online chat through to personal concierge service. They set out to develop these products and launch them onto the market in place of their current offerings.<\/p>\n

If, as they hope, this is a successful venture, they will retain their current customer base and continue to acquire additional market share through the high churn the industry is experiencing. However, the model is easy to duplicate and their competitors will no doubt adapt by introducing similar, or potentially better, products. They will need to prepare in advance to react to this change in the market if they are to stay ahead of the game.<\/p>\n

And what if they\u2019re wrong? That\u2019s a significant amount of effort and investment to waste on an unsuccessful venture, not to mention the potential reputational damage. This is the danger of linear thinking.<\/p>\n

Diamonds are forever<\/h2>\n

To address this, each stage in the Entrepreneurial Cycle needs to exploit the elegant wisdom of B\u00e9la H. B\u00e1n\u00e1thy. The earlier diagram, however, fails to convey this. It\u2019s drawn in a way that implies movement from one state to the next is a linear, predictable activity, and the example above includes elements of this linear thinking style. It should be clear from the example that the decision making involves a lot of assumptions and gut feel decisions. There is little room for uncertainty or verification.<\/p>\n

So now we need to overlay this cycle with the diamond model to make it more complete and add some rigour to the process of investigation and decision making. For ease of drawing, I\u2019ve stretched it out horizontally, but please remember it\u2019s cyclic:<\/p>\n
