Show Me The Data

I was giving a potted history of my working life to an undergraduate Engineer yesterday. After a few minutes I noticed the haunting theme that was running through my stories, about the need for good data to make informed decisions.

Like many things that become second nature, the use of good data is vital in most cases to determine how to approach an improvement opportunity within a business. It's where I try to start, although in many cases it is a case of gathering the data in the first place, rather than just tapping into a rich vein currently sitting there.

I should also state, at this point, that some businesses do have data for data's sake. Time wasted on recording information that will never be used is just that - a waste that the business could most likely do without.

Reflecting further on the need for good data I thought about a number of recent projects where data was vital:
  • The new factory layout that needed throughput data in order to calculate floor space requirements.
  • The 'time lost' information that informed us on how to change the shop floor support approach.
  • The justification for a new piece of equipment that (initially) no-one thought needed to be purchased.
  • Production volumes, allowing focus to be created on which products to streamline first.
  • Sales information, helping us choose which parts MRPII could manage for us automatically.
I'm sure you get the point. Good data is central to solid decision making and a lack of data can certainly stall the decision making process. That seems pretty obvious to most of us, if we don't know what to review and compare how can we be expected to make rational and well informed decisions.

Be economical with your data gathering though, good data is usually just a few steps away. Be clear about what you need and don't end up making a whole new job for yourself (or your team!) as data gatherers.

The summary of my talk with my Engineering friend, and the point of this blog post, is that good data is vital to decision making. If you don't have it, and need to make a decision soon, then it is worth investing the time to go and find it.

Stop firefighting, start performing!

Another weeks passes and another example of unnecessary fire fighting demonstrated by a business I have been to help. If you have this taking place in your business, let me ask you a few questions: 1. What keeps on happening? Regain control with this practical book Can you pin down what it is that you keep having to do, to get out of trouble? If you can't, is there a pattern you can observe? 2. Do you want it to stop? Is it causing you enough of a problem that you want it to stop? If the answer is yes, keep reading, if not park it for another day. 3. Find out what is going on Do you know why you are having this issue? If you aren't sure where the issue is arising from, then take a few minutes to have a look around. When you have some idea, go to the next step. 4. Cause and effect Do you know what is truly causing the fire fighting situation? If you spend the time to get to the root cause of the situation , you have a good chance of permanently eliminating this situation. Most p

Kaizen improvements need to be specific

Do you find that your Kaizen improvements don't always go to plan? If you do, then you're with the majority! Whilst there is great deal of 'trial and error' there is a simple approach that can help. Available from Amazon Being specific about critical parts of your improvement can uplift your results. So, how do you go about doing this? The most direct route is to be clear about which parts of your improvement are critical. From here you can explain, in detail, what you want for those items. This might take some practice as many of us have become lazy in this regard. We take it for granted that our team 'get us' and will know what they need to do. If you ever feel that something basic is missing from an improvement ask this question: "What does good look like?" The answer should put you back on track.

Are your teams clear?

I have recently finished working with a team that were struggling. They were struggling to meet their production schedules. They were struggling to respond to customer enquiries on time. They were burnt out and frazzled. After some prodding and poking it became clear what their issues were. In particular, it became obvious that expectations of the team weren't clear or defined. Defining what you expect from teams is a standard management approach. The problem with most teams is that leadership describe the standards in vague terms . So, what happens if you get the standards crystal clear? You should expect to see the team produce the right outputs. They should produce the outputs at the right time. And, they should produce them in an agreed way. Be clear with your teams. Ask the question: What does good look like? If you want to get some more ideas on how to define effective standards and visions, get your copy of my book today . What does good look like? is a practical guide to h
