Five Whys vs. Fishbone

Every once in a while a great article that explains an idea well appears that is worth sharing. This is one example, from HRDQ:

Five Whys vs. Fishbone Diagrams for Root Cause Analysis.

The article is worth reading but in brief, it describes two powerful and commonly used root cause analysis tools and how to use them. It makes a convincing case that it is not exactly one vs. the other -- start with the classic Fishbone diagram. If you uncover what appears to be one dominant cause path, drill down on that path using the 5 Whys. That's the order:

1. Fishbone

2. Five Whys

I use variations of each of these tools in our workshops on Creative Problem Solving. The common versions are still effective and will save you time in problem solving.

The root cause analysis is essential. Done properly and thoroughly it will prevent you from chasing solutions that do not actually solve the problem.

What problem are you working on today? Have you identified the root cause?

How's Your Reputation

How important do you think it is to sustain a positive leadership reputation? It matters to your team. It matters to any future team that you might be leading. Your reputation tells a story about how you operate, how you facilitate and how you achieve your results. Leading positive change builds credibility. Making a difference right now builds credibility. Keeping your promises and showing care for others establishes the kind of character that people want to work with and maybe even follow. What positive change are you currently working on? -- doug smith

Where to Start?

It's harder to solve a problem alone when you are at the center of the problem. Get another perspective. Stay open to your own part of the problem. Sometimes, deep into the search, we discover that we could be the cause. Start with reflection. It could provide direction. -- doug smith

Creatively Human

In a world where anything can be duplicated, create what cannot be duplicated. -- doug smith

Dig deeper

Obvious solutions are great, except that they seldom work. The chances are that the solution that first occurs to you has already been tried. Sticky, mysterious, subtle problems evade the obvious. They hide. They mask. They simmer. Mysterious problems seldom surrender to obvious solutions. Dig deeper. -- doug smith

More signal than noise

Criticism produces more noise than signal. The recipient will hear mostly noise. Find another way to share the relevant information and it will sound more like advice than insult. Here's one other way -- ask the person you want to give advice to what their advice is for improving performance. Listen. Find the tone. Catch the brilliance. Support the useful observations. When we coach positively with enthusiasm our advice lives longer. What do you think? -- doug smith

Extremes

Do you know what it is like to work for an unreasonable boss? When no matter what you do is ever good enough it can become demotivating, even crippling. We do need to challenge our teams, but not to esteem crushing extremes. Unreasonable expectations cause disappointment. High performance? Yes. Perfect performance? Not attainable. -- doug smith

Share the Load

Are you in charge? Is the team your responsibility? Every team needs more than one leader. The highest leverage strategy a leader can employ is to develop more leaders. Build that mighty team one person at a time. Share the load. -- doug smith

Relationships and the Mission

Team relationships get complicated. Sorting them out is one more tough leadership task. Recruiting the right people for your team is the first step, followed by keeping the communication on your team clear, open, honest, and respectful. A team of superstars who cannot get along will not make for a successful team. Interpersonal dynamics matter considerably. Team relationships make more sense when the mission matters. The best reason for a team to get along with each other is so that they can achieve their mission. Start there. Focus there. -- doug smith

Tough Choice

As a customer, you'd know what you want. That's worth keeping in mind. Sometimes things might seem good for business but be bad for customers. If money is the only bottom line we find ourselves at the bottom quickly. It takes courage to say no to something that is bad for your customer but profitable for your business. People with that kind of courage are people worth doing business with. -- doug smith

Solve It and Move On

If you work long enough you'll notice something that will give you a strong perspective. Every year there is a new problem that is capable of completely destroying you. Solve it and move on. No reason to surrender now. -- doug smith
