I’m reposting the email charter here to get more coverage for this intelligent idea. My contribution is that brevity is good, but rude is bad. Please and thank you are not optional. One can communicate succinctly without being rude if you think before you click SEND. Try to imagine how you would respond to your message and word it accordingly.

The Email Charter was created in response to widespread acknowledgement that email is getting out of hand for many people. It started life as a blog post by TED Curator Chris Anderson and TED Scribe Jane Wulf. The idea struck a chord. More than 45,000 people read the post and and it generated hundreds of tweets, comments and suggestions. That is how the final Charter was shaped. Some of the key contributors are listed here.

The Charter is a private, non-commercial initiative, a simple ‘idea worth spreading’.

If you have comments or suggestions, please join the conversation here.

Please consider sharing the Charter with others by tweeting, blogging, or adding it to your email signature.

Thank you!

 

The Problem

The relentless growth of in-box overload is being driven by a surprising fact:

The average time taken to respond to an email is greater, in aggregate, than the time it took to create.

This is counter-intuitive because it’s quicker to read than to write. So you might assume a typical email takes a few minutes to write, but only a few seconds to read. However, five other factors are outweighing this.

- The act of processing an email consists of much more than just reading. There is a) scanning an in-box, b) deciding which ones to open, c) opening them, d) reading them e) deciding how to respond f) responding — which may well involve writing an email of similar length back g) getting back into the flow of your other work. So the arrival of even a two-sentence email that is simply opened, read and deleted can take a full minute of your available cognitive time.

- Many emails contain open-ended questions that can’t rapidly be responded to. “What’s your opinion on all this?” “How should I move forward?” Easy to ask, hard to answer.

- Many emails are sent to multiple recipients. It takes no time to add another cc, but each additional recipient multiplies the total response time demanded.

- Many emails contain additional text that has been copied and pasted from other documents or a lengthy thread that is simply being re-forwarded.

- Many emails contain links to web pages or videos. Easy to add a link. But it may take minutes to view it.

Now consider that the amount of time people are spending on line is increasing. It is, after all, a seductive place to hang out. As social creatures, it’s the most natural thing in the world to want to use that time to reach out to others. What is more the range of ‘distractions’ online is growing every year. And it’s easy (and often wonderful) to share them with our friends and colleagues. Just copy a link, paste and send… and boom, the world’s cognitive capacity takes another hit!

The result of all this is a deadly upward spiral. Every hour you spend writing and sending email is probably consuming more than an hour of the combined attention of your various recipients. So without meaning to, we’re all creating an ever growing problem for each other.

An email inbox has been aptly described as the to-do list that anyone in the world can add an item to. If you’re not careful, it can gobble up most of your working week. Then you’ve become a reactive robot responding to other people’s requests, instead of a proactive agent addressing your own true priorities. This is not good.

This phenomenon can be thought of as a potent modern tragedy of the commons. The commons in question here is the world’s pool of attention. Email makes it just a little too easy to grab a piece of that attention. The unintended consequence of all those little acts of grabbing, is a giant rats nest of voracious demands on our time, energy and sanity.

How might the Charter solve this? See the solution.

The Solution

 
10 Rules to Reverse the Email Spiral

1. Respect Recipients’ Time

This is the fundamental rule. As the message sender, the onus is on YOU to minimize the time your email will take to process. Even if it means taking more time at your end before sending.

2. Short or Slow is not Rude

Let’s mutually agree to cut each other some slack. Given the email load we’re all facing, it’s OK if replies take a while coming and if they don’t give detailed responses to all your questions. No one wants to come over as brusque, so please don’t take it personally. We just want our lives back!

3. Celebrate Clarity

Start with a subject line that clearly labels the topic, and maybe includes a status category [Info], [Action], [Time Sens] [Low Priority]. Use crisp, muddle-free sentences. If the email has to be longer than five sentences, make sure the first provides the basic reason for writing. Avoid strange fonts and colors.

4. Quash Open-Ended Questions

It is asking a lot to send someone an email with four long paragraphs of turgid text followed by “Thoughts?”. Even well-intended-but-open questions like “How can I help?” may not be that helpful. Email generosity requires simplifying, easy-to-answer questions. “Can I help best by a) calling b) visiting or c) staying right out of it?!”

5. Slash Surplus cc’s

cc’s are like mating bunnies. For every recipient you add, you are dramatically multiplying total response time. Not to be done lightly! When there are multiple recipients, please don’t default to ‘Reply All’. Maybe you only need to cc a couple of people on the original thread. Or none.

6. Tighten the Thread

Some emails depend for their meaning on context. Which means it’s usually right to include the thread being responded to. But it’s rare that a thread should extend to more than 3 emails. Before sending, cut what’s not relevant. Or consider making a phone call instead.

7. Attack Attachments

Don’t use graphics files as logos or signatures that appear as attachments. Time is wasted trying to see if there’s something to open. Even worse is sending text as an attachment when it could have been included in the body of the email.

8. Give these Gifts: EOM NNTR

If your email message can be expressed in half a dozen words, just put it in the subject line, followed by EOM (= End of Message). This saves the recipient having to actually open the message. Ending a note with “No need to respond” or NNTR, is a wonderful act of generosity. Many acronyms confuse as much as help, but these two are golden and deserve wide adoption.

9. Cut Contentless Responses

You don’t need to reply to every email, especially not those that are themselves clear responses. An email saying “Thanks for your note. I’m in.” does not need you to reply “Great.” That just cost someone another 30 seconds.

10. Disconnect!

If we all agreed to spend less time doing email, we’d all get less email! Consider calendaring half-days at work where you can’t go online. Or a commitment to email-free weekends. Or an ‘auto-response’ that references this charter. And don’t forget to smell the roses.

Chillin’ with Old Man Winter…

Old-man winter is nipping here in the northern hemisphere. Snow is already falling in some areas and a natural question extends to winter and its effect on water softeners and filtration systems. Water temperature has a significant effect on the capacity and functionality of many water treatment processes. A smart dealer must be aware of the influence of ambient temperature and water temperature on the effectiveness and longevity of the water quality improvement systems that they sell, install and maintain. As a covalently bonded hydrogen compound, water behaves quite uniquely when temperatures drop. As it cools, water’s density tends to increase (like most other compounds) until it reaches the anomalous expansion rangeof 4-0°C (39.2-32°F) at which point its density decreases. This unique property gives ice its ability to float which prevents lakes from freezing solid, and of course allows for water to burst plumbing pipes and potentially wreak havoc on water treatment devices.

Membrane separators

Since water increases in density before reaching the anomalous expansion range, membrane flux in reverse osmosis, nanofiltration and ultrafiltration systems will decrease significantly as water temperatures drop. Smart dealers will make the appropriate adjustments and compensations as recommended by the equipment manufacturer to deliver the maximum amount of permeate without causing premature equipment failure.

Backwashing filters

Increasing water density means that less backwash flow rate is required to lift the media in a tank. Consult with your OEM about designing equipment with sufficient freeboard and appropriately sized backwash flow controls to ensure that no media is lost from the system.

Water softeners

While resin manufacturers are usually concerned with excessively high water temperatures on ion exchange resin, cold water temperatures also present their own share of issues. Cold water decreases resin kinetics and increases salt dissolution times. Slow kinetics cause a dramatic decrease in ‘effective’ system capacities, which usually causes customers to end up with hard water bleed-through unless the dealer makes appropriate programming compensations. Naturally, systems with resin status sensors will automatically compensate for this phenomenon. Most dealers will derate the system by as much as 30 percent if it will be exposed to cold influent water in the range of 1.6  to 7.2 °C (35 to 45°F).

Winterization procedure for water softeners

There are many opinions on how to winterize water softeners. Some dealers believe that since most softeners installed in cold climates are located in basements that they require no winterization. I believed that until I witnessed ambient temperatures in Montana basements hovering at -10F (-23°C) during January in unoccupied vacation homes. These low ambient temperatures cause fiberglass resin tank to split as if they were opened by a zipper. Not a healthy situation when things finally thaw out in spring! Winterization is normally only performed when the home/business will be unoccupied and marginally heated during winter.

A simple and generally safe and effective single tank water softener winterization procedure is as follows:

  1. Initiate a manual regeneration cycle.
  2. Advance manually to the brine/rinse ion exchange cycle.
  3. Induce a saturated brine solution into the softener along with resin cleaner and disinfectant into the mineral tank. (five gallons of brine per cubic foot of resin)
  4. Bypass the system and terminate the regeneration cycle.

If the building will be unheated and piping blown-out or drained down, the following additional steps should be performed instead of bypassing the system:

  1. Inject compressed air through the brine port at a maximum of 20 psi until all brine has been purged from the resin tank down the drain.
  2. Advance through each remaining regeneration step to allow water to drain from the control head.
  3. Leave the system in service (Do not bypass).
  4. Disconnect and remove the float from the brine tank; drain and store in a safe place.
  5. Drain down or blow down the home as per normal winterization procedures.

Some dealers perform winterization by inducing antifreeze into the mineral tank with a pump. When using antifreeze, be careful to use only propylene glycol (food-grade) antifreeze. Ethylene glycol antifreeze is highly toxic and should never be used for winterization. Concentrated polyethylene glycol is acts an effective anti-bacterial in most cases.

Springtime startup procedures should include a rigid disinfection and rinsing protocol to provide for the health and safety of the establishment and its occupants.  As with all things, be sensible, thoughtful and methodical in your approach to winter.  Consult with your OEM and dealer network to ensure that you are employing the best industry practices to give your customers the very best water year-round.
