As the online landscape evolves businesses are continuing to see the value in the time-proven benefit of pulling in customers organically.
As these numbers demonstrate a new form of normal for internet use, it becomes apparent that pull focused marketing is an absolute necessity for future business growth. But the push strategy can be tempting too. The truth is that businesses find the best success when they focus on a multi-channel, multi-strategy approach in both push and pull.
These two broad categories are simply too important to focus on just one. But what do they encapsulate? Which specific marketing methods makeup the difference between push and pull marketing strategies? More than half of marketers claim that improving their SEO is their main pull marketing priority. This means that an SEO strategy is important for netting the most possible traffic for your business, if you want to rank as highly as possible.
SEO focuses on making a website optimized for the algorithms that search engines used to index and rank them. The downside to SEO is that it requires a fair amount of initial investment — either lots of work to optimize the site or spending money to pay for professional SEO services. It can also sometimes take months to see results as re-indexing and ranking-shifts on Google and Bing tend to play out slowly. But the major advantage of SEO is that the costs are relatively low compared to paid-ads, and the pay-off can be very good in the long-term.
For most businesses, the benefits justify the costs. As websites optimize their product pages and service-pages for SEO it can help increase organic traffic by increasing their 1 st page search engine rankings. A professionally search optimized site can bring in incredible amounts of static revenue for months or years to come — with perhaps only maintenance required.
The truth is that social media offers opportunities in both push and pull as well. But social media is also an increasingly important paid ads channel as well. Sites and apps like Facebook, Instagram, LinkedIn, Snapchat, Pinterest and more a offer litany of ad styles — and they represent some of the best sites for social media marketing. The difference between push and pull marketing strategies here is once again the difference between organic and paid. In fact the wealth of data that social media offers is one of its biggest strengths.
User data like usage habits, interests, likes, biographical facts, geographical data, cohorts and more mean that advertisers are able to maximize return-on-ad-spend ROAS by targeting the best shoppers for their business.
When applied to manufacturing, the tautness results in less WIP and processes moving at identical speeds. When the rope is fully taut, you have one piece flow. I agree the defining action of a pull system is that it explicitly limits WIP, but it sounds like the initial intention was less about limiting WIP and more about limiting the speed of the upstream processes. Most pull systems achieve that by removing the buffers that allow different rates of production to be sustained for longer periods of time.
Without that buffer, there is no value to dedicating resources to improving a process that is already regularly being blocked by the downstream process, and balance should naturally result as the actual bottlenecks are made clearer by a lack of WIP covering them up.
In other words, if you attack WIP, you naturally work towards balance or pull because it makes that motivation stronger by eliminating your safety net for mistakes and the perceived reward for over production, where as if you start by attacking imbalance, there will be nothing motivating you to remove your safety net as it becomes less necessary.
Hi Mack, WIP is necessary. The question is: how much do you need, and how can you change your system to get away with less. For me, the bigger problem is the imbalance mura , which causes a lot of subsequent problems, one of which is WIP.
Pull is flow, push is not. I admit, I had understood it slightly wrong myself. But it really makes sense. Thanks for this great clarification! One generalization I would make, though.
The same effect of controlling WIP applies perfectly e. Virtually any process I guess. Hi Arto, thanks for the input. Hello Cris: You always posted good articles. Thank you. Push is a randomly way that originated all the kinds of waste for instance is expensive for your Company to still keep it. In an stable production area pull system works perfect. Dedicated: Resources, locations, takt time. In a Push system no have clearly agreements. Hi Pedro, not sure if I understood or agree with your definition of pull.
I strongly believe in the upper limit on inventory as a definition of pull. Hi Agus, demand prediction is always tricky. A not perfect but often useful way is to take last years demand and adjust for growth shrinking.
Obviously does not work for new products. Hi Mr. First of all, wonderful article. I do have one question. Hi Rafael, Toyota does use Pull throughout their value chain. Please note that they mostly produce make to stock, which can be compatible with pull. Pull is almost always better than push.
The fact is; regardless of your business model, the idea behind the system is to create a value stream that is as lean as possible in order to avoid waste through over production. So when you run a Kan-Ban at critical points in your process, the signal to produce cannot exceed the amount of actual cards in your system. Instead, as Lean Practitioners, we would want to look at if the amount of cards is adequate to meet the demands of the customer assuming that demand has increased consistenly in this scenario.
When all those cards are used regardless of MTS or MTO , that is a signal to not produce anymore until such time as they are needed. The agreed upon Lead Time is extremely important. There are extreme cases of highly customized products where this becomes more difficult. But it is still possible to pull common items through inventory to reduce the amount of waste think fasteners, tooling, etc. Thanks for your articles! Always grateful for the opportunity to deepen my learning.
So… a fast food place, that has limits within their processes would still be considered Pull? And the work is really understanding the right buffer size depending on the time of day? I suppose made to order in this case just might have a lower WIP limit?
But on some levels, those WIP limits are informed by their demand, be it forecasted or actual. This seems to be in line with misconception 2 that forecasted demand systems are push. Hi Chris, I read your post. I full agree on this definition of pull. I have also gone through factory physics paper on pull and was inspired to write about the push vs pull distinction.
I believe, this mis-conception has prevented companies from adopting pull more widely. Thanks again. Even to estimate the size of kanban or the WIP-Limit we must have a way to estimate what is the near-future demand is going to look like — this is then some kind of forecasting. Very good insights. A forecast is also needed for pull production although only the MTS section needs a product dependent quantity, the MTO section needs only the overall workload. Chris, Thanks for your comments.
I think the need of the hour is strict definitions for push and pull. And then going on to say there is no need of forecasts in Lean Pull method thus giving raise to all kinds of debates and arguments from the forecasting camp — who obviously feel offended by such statements!!
I find it more confusing than helpful. I would rather try to emphasize the main message that pull is an upper limit on WIP or work content. Thank you very much for your articles, it is always crystal clear and very well illustrated, I learn a lot. Regarding the difference between Push vs. Thus a stock of inventories permits a factory to operate without concern for very short-run fluctuations in product orders.
Energy storage in the tissues of a predator enables it to cope with uncertainties in the availability of prey. A modest excess of capacity in electric generating plants avoids the need for precise estimation of peak loads. Homeostatic mechanisms are especially useful for handling short-range fluctuations in the environment, hence for making short-range prediction unnecessary.
In whatever directions the environment changes, the feedback adjustment tracks it, with of course some delay. It is well known in control theory, however, that active, feedforward control, using predictions, can throw a system into undamped oscillation unless the control responses are carefully designed to maintain stability. Because of the possible destabilizing effects of taking inaccurate predictive data too seriously, it is sometimes advantageous to omit prediction entirely, relying wholly on feedback, unless the quality of the predictions is high.
This insight makes me say that Pull system definition is: A feedback loop controlling work released in the system. Pull systems release work into the system according to feedback loops: when inventory falls under a lower limit, when an order is complete… ex: kanban, drum buffer rope, conwip, reorder points, DDMRP.
So changes in a stock affect the flows into that same stock. Moreover, Because of feedback delays, by the time a problem becomes apparent it may be difficult to solve. Here comes the push systems. Push systems do not decide according to past events, but according to future events which are uncertain. This is what MRP does as far as I know. The problem with purely push system is that they release work in the system according to imperfect predictions, imperfect plans and imperfect models false demand, false lead times, false bills of material, false capacity.
Errors can be passed and amplified through the whole supply chain, excess inventory clogs the plant, management waste time and energy through expediting, lead times increase so you need further predictions, etc. Yet, if your anticipations and your models are reliable, it can help I guess. In the end, as Herbert Simon said, Pull is usually better because even though it works on reaction mode, with few inventories reaction is quick lead times are shorter.
Hi Chris, Great article. It seems to me that another embodiment of a pull production system is one where WIP is limited by production capacity. Somewhat like DBR, but also different because all operations limit production, not just an identified bottleneck. The signal to produce is sent upstream by a downstream operation when the downstream operation completes work and will hence be ready to produce more. Hi Dale, DBR als has a limit, but it is a workload limit.
