Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mihi quidem Antiochum, quem audis, satis belle videris attendere. Quid, si etiam iucunda memoria est praeteritorum malorum? At, illa, ut vobis placet, partem quandam tuetur, reliquam deserit.
Egone non intellego, quid sit don Graece, Latine voluptas? Et non ex maxima parte de tota iudicabis? Ergo opifex plus sibi proponet ad formarum quam civis excellens ad factorum pulchritudinem? Non enim, si omnia non sequebatur, idcirco non erat ortus illinc. Dolor ergo, id est summum malum, metuetur semper, etiamsi non aderit; Et non ex maxima parte de tota iudicabis?
Mihi quidem Antiochum, quem audis, satis belle videris attendere. At quanta conantur! Mundum hunc omnem oppidum esse nostrum! Incendi igitur eos, qui audiunt, vides. Certe, nisi voluptatem tanti aestimaretis. Duo Reges: constructio interrete. Bonum integritas corporis: misera debilitas. Si verbum sequimur, primum longius verbum praepositum quam bonum.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. An haec ab eo non dicuntur? Nam illud vehementer repugnat, eundem beatum esse et multis malis oppressum. Duo Reges: constructio interrete. Est enim effectrix multarum et magnarum voluptatum. Quid censes in Latino fore?
Maximas vero virtutes iacere omnis necesse est voluptate dominante. Ut placet, inquit, etsi enim illud erat aptius, aequum cuique concedere. Quid est igitur, inquit, quod requiras? Aeque enim contingit omnibus fidibus, ut incontentae sint. Inscite autem medicinae et gubernationis ultimum cum ultimo sapientiae comparatur. Tum Piso: Quoniam igitur aliquid omnes, quid Lucius noster? Non est igitur summum malum dolor. Illa enim, quae prosunt aut quae nocent, aut bona sunt aut mala, quae sint paria necesse est.
Qua ex cognitione facilior facta est investigatio rerum occultissimarum. Nunc agendum est subtilius. Ne in odium veniam, si amicum destitero tueri. Sed ne, dum huic obsequor, vobis molestus sim. Qui enim existimabit posse se miserum esse beatus non erit. Diodorus, eius auditor, adiungit ad honestatem vacuitatem doloris.
The main issues with the diagram are the differentiation between causes and sub causes. For example, some causes might be complex, with many elements below them, becoming impractical to capture in the diagram. By breaking it up into separate categories, the diagram also does not lend itself to a more connected view of challenges.
Finally, there is no clear prioritisation within the diagram — all causes seem equal, when in reality a sub cause, which is visually small, might be the key issue. Other causes and sub causes therefore might become a distraction.
Internal damages at IKEA.
This paper from Ikea in Portugal describes a process improvement process to address the level of internal damages in Ikea stores. The diagram below was part of a broader analysis process.
The fishbone or Ishikawa diagram, also known as the cause-and-effect diagram, is a core tool within quality management and is commonly used for improvements in products, manufacturing and other fields.
Use the following examples of connected and complementary models to weave the fishbone diagram into your broader latticework of mental models. Alternatively, discover your own connections by exploring the category list above.
Connected models:
- 5 Whys: in digging to root cause, use this as part of the fishbone process.
- Second order thinking: to go beyond the initial cause to sub causes.
- 4Ps of marketing: as possible categories.
Complementary models:
- Risk matrix: to consider potential issues with consequences versus likelihood.
- Chain reaction/ domino effect: to consider the flow on effects of potential issues.
- First principle thinking: to identify and go below assumptions.
- Occam’s razor: to cut to the core of the issue.
- Divide and conquer: separating out and addressing potential causes.
The Fishbone Diagram was created by quality management pioneer Professor Kaoru Ishikawa in 1968. Ishikawa, an engineer, was a leader of quality management at Kawasaki at the time. In his 1986 book, Guide to Quality Control, Ishikawa argued that there were six other key quality tools in addition to what he called the ‘cause-and-effect diagram’, which were: control chart, histogram, flow chart, run chart, scatter diagram and Pareto chart.
