What effective communication means: the right information, to the right person, in time

1. Effective communication has to pass three tests, because sending a message and communicating it are not the same thing.
   1. The right person: the information reaches whoever has to act on it, not everyone in the building and not only the manager who already knew.
   2. In time: it arrives while the receiver can still do something with it, since a change to an order sent after the delivery van has left changes nothing.
   3. Understood: the receiver takes the same meaning from it as the sender intended, which is what feedback tests, because a reply or a repeated-back instruction proves understanding where silence proves nothing.

What a business gains when communication works

1. Fewer mistakes: staff who know exactly what is expected do the job right first time, so less material is wasted and less labour is paid for twice.
2. Faster response: a decision reaches the people carrying it out in hours rather than days, so the business can cut a price or pull a faulty batch before customers or rivals react.
3. Better morale and lower staff turnover: staff who are kept informed about changes feel trusted and valued, so fewer of them leave and the business spends less on recruiting and training replacements.

Insufficient communication: what too little does to efficiency and motivation

1. Mistakes and duplicated work: two people process the same order because neither was told the other had it, so the labour is paid for twice and the customer still waits.
2. Wasted time: staff stop work to chase a manager for information that should have arrived with the task, so output per hour falls while the wages carry on being paid.
3. Low morale: staff who hear about a change from a customer rather than from their manager feel left out, so motivation drops and absence and turnover rise.
4. Poor customer service: staff who do not know that an offer has started or that a product has been withdrawn give the wrong answer, so the business looks disorganised and the sale goes elsewhere.
5. Slow decisions: a manager waiting on figures from another department cannot choose, so a supplier discount or a delivery slot is gone before anyone acts.

Excessive communication: what too much does to efficiency and motivation

1. Excessive communication is the opposite fault: staff are copied into every email, added to every group chat and booked into meetings that have nothing to do with their own work.
2. Efficiency falls because the working day goes on reading messages and sitting in meetings instead of doing the job, so a supervisor booked into three meetings has three fewer hours on the shop floor and the orders go out late.
   1. The message that mattered is lost among the ones that did not, so a price change or a safety notice is skimmed past with the rest and missed altogether.
3. Motivation falls because being copied into everything while having no say in any of it is draining, and staff soon learn that most of what arrives can be ignored.
   1. Messages arriving at any hour blur the line between work and home, since staff who feel expected to answer in the evening never properly switch off and come in tired.
   2. A manager who forwards everything signals that they do not trust staff to work out what matters, so experienced people feel watched rather than relied on.
4. Too little and too much end in the same place for the business, because output per hour falls either way and the staff with the most choice about where they work are the first to leave.

Barriers: why messages fail, and where structure comes in

1. Too many layers: a message sent down the long chain of command of a tall structure is reworded at every level it passes, so it arrives late and distorted, which is one of the main arguments for the flatter structures covered in the previous guide.
2. The wrong medium: a long email about an urgent shift change is read too late, and a quick verbal instruction for a complicated safety procedure leaves no record anyone can check.
3. Information overload: so much is sent that the one message that mattered is skimmed past with the rest, which is the barrier that excessive communication builds.
4. Language and jargon: the receiver does not know the technical words or does not read English fluently, so they act on a guess instead of the instruction.
5. No feedback: nobody replies or checks, so the sender never learns the message was misunderstood until the work comes back wrong.
6. Technology has flattened two of these barriers, because messaging apps, video calls and shared systems reach a home worker or a distant branch instantly, though the same tools are what make excessive communication so easy to fall into.
