Slow turnaround of work generates customer dissatisfaction and reduces cashflow.

Completing tasks quicker can be accomplished with AI by reducing these fundamental frictions;

1. Speed up intra-team and/or stakeholder communications turnaround times
2. Reduce lag time in starting tasks
3. Reduce the time it tasks to produce the work

AI is proving to have a dramatic impact on improving all three of these pressure points, thus improving the satisfaction levels of customers and other stakeholders.

Inspira’s Water platform can provide estimates as to how much ‘delivery time’ was saved when delegating work to Sidekicks. This estimate is generally conservative, and includes the assumption that tasks are being completed through team collaboration (not a one-man show).

Here is the short version of how we estimate delivery times….

Our formula calculates how much ‘human-equivalent’ time was saved when Sidekicks do the work, vs when humans do the work without Sidekicks. It only calculates the work performed by the Sidekick, and does not include work performed by the human handlers, which could be as much as 20% of the total.

Example of a task where:

• 4 messages are sent and responded to. This is an arbitrary number of messages and could be any number.
• 14.36 hours lag in responding to each message, including non-work hours (relying on the research and data below). In production, the Water platforms calculates a new average every month, using actual data.
• 0.5 days (12 hours) in start-lag time before the work begins (again relying on the research and data below)
• 6 hours of ‘human-equivalent’ labor required to perform the work. This is arbitrary and could be any number of hours.

Formula: messages*lag + start-time-lag + production-time

4*14.36 + 12 + 6 = 75.44 hours, or 3.11 days to complete the 6-hour task in the above example.

The actual numbers will be slightly different from company-to-company, but the principle holds true… by reducing communication lag time, start-time lag, and production time, overall delivery times can be sped up dramatically.

Here it is in more detail…

Speed up intra-team and/or customer communications turnaround times

Modern teams are exchanging more messages than ever, across both email and instant messaging platforms. Research indicates that the time spent on workplace communication and collaboration has surged by over 50% in the past two decades (blog.rescuetime.com). This flood of emails, chat messages, and notifications means employees dedicate a significant portion of their workday just to reading and responding to communications. Understanding how long it takes staff to clear or respond to messages – and how this varies by channel (email vs. tools like Slack or Microsoft Teams) – is crucial for optimizing productivity and setting realistic expectations. Below, we delve into data from studies and surveys that quantify response times, message loads, and their impact on workflow efficiency.  

Email Communication: Volume and Response Times  

Email remains a staple of inter-team communication, but it often involves substantial delays and effort to manage. Surveys and analytics studies have measured how much time workers put into email and how quickly they tend to respond:  

– Hours Spent on Email: Employees spend a remarkable amount of time drafting and reading emails. A Slack/OnePoll survey of small businesses found that workers write about 112 emails per week, averaging 5.5 minutes per email, which is roughly 10–11 hours per week spent on email composition alone (slack.com). A similar poll in the UK reported about 99 work emails written weekly (≈9 hours) per employee (www.salesforce.com). This is almost a quarter of a 40-hour workweek dedicated just to email writing.  

– Emails Received and Ignored: Many messages never even get fully read. Respondents said only 36–42% of the emails they send are actually fully read and understood by recipients (slack.com) (www.salesforce.com) – meaning the majority of email content goes unnoticed. At the same time, employees often ignore incoming emails: on average 6–8 emails per day are deleted or skipped based on the subject line alone (slack.com) (www.salesforce.com). This triaging isn’t without consequence – nearly 30–45% of workers admit that skipping emails in this way has caused them to miss important information, like a project deadline or new business lead (slack.com) (www.salesforce.com). Such data highlights how email overload can lead to critical messages being overlooked.

– Typical Response Latency: The time lag in email communication is significant. One analysis of hundreds of professional mailboxes found an average email response time of about 3 hours 38 minutes (during work hours) (www.prnewswire.com). Other reports suggest that many workplaces expect even faster turnaround – citing an average email reply time closer to 90 minutes (zipdo.co). In other words, employees often take on the order of 1.5 to 3.5 hours to respond to an email, though response times can vary widely by urgency and job role. This multi-hour delay contrasts with real-time communication channels and can slow down the resolution of time-sensitive issues.

– Unanswered Questions: Even when emails do get a response, they may not fully resolve the matter. In Slack’s survey, 62% of workers said it’s common that their email replies don’t address all the questions posed (slack.com). This suggests email threads often require multiple back-and-forth messages to reach clarity. Each extra exchange prolongs the total time to resolution – potentially spanning days if each reply takes hours – and contributes to email thread fatigue.

Overall, the data paints email as a time-consuming medium: employees devote many hours to it weekly, responses aren’t instantaneous, and a good portion of that effort fails to achieve prompt, clear communication. These findings prompt organizations to consider how reliance on email might be streamlined or supplemented with faster tools for certain needs.

Instant Messaging (Slack, Teams): Speed and Response Expectations  

Collaborative platforms like Slack, Microsoft Teams, and similar instant messengers have transformed inter-team communication by enabling near-instant exchanges. They promise faster coordination, but also come with their own challenges regarding responsiveness and information load. Key findings from studies and surveys include:  

– Rapid Back-and-Forth: Unlike emails, which may sit in an inbox for hours, messages on Slack/Teams pop up in real-time, prompting much quicker attention. Many employees keep these apps open throughout the workday, leading to responses often within minutes, not hours (especially when both parties are online). This immediacy helps teams clarify questions or make decisions faster. As one business leader noted after shifting from email to Slack, “We don’t waste time drafting up emails that may not be read… Instead, we bring everyone into one place… to align faster on goals”, highlighting how chat can compress communication cycles (slack.com). Issues that might have taken days of email exchanges can be resolved in a quick series of chat messages. 

– Time Saved vs. Email: Surveys suggest that replacing internal email threads with chat channels can save employees a significant amount of time. Slack’s research found that the hours previously spent writing formal emails could be reallocated to more productive work. For example, by using a real-time messaging approach, employees might save on the order of 9–11 hours per week that they would have otherwise spent composing emails (slack.com) (www.salesforce.com). Those hours are instead used for direct problem-solving in chat or other tasks. Essentially, quick one-line pings or an interactive discussion in a channel can accomplish what would require lengthy emails, drastically reducing the “clearance time” for a conversation. Indeed, some teams have reported cutting internal email volume by about 50% after adopting Slack (as in the case of Pet Circle, which halved its email use) (slack.com), replacing those communications with faster chat exchanges.

– Always-On Expectations: The flip side of instant messaging’s speed is the expectation of constant availability. Employees feel pressure to check and respond to messages rapidly to avoid blocking colleagues. This “always-on” culture extends beyond regular work hours. For instance, 94% of people say they check work communication (e.g. email or chats) outside of normal working hours (zipdo.co), illustrating that many do not disconnect after the workday, likely due to the ubiquity of mobile chat apps and the norm of immediate response. Microsoft’s data on Teams usage similarly observed that the volume of chats and off-hour messaging has risen significantly in recent years, blurring the line between work and personal time. The near real-time nature of Slack/Teams means employees often feel an obligation to clear notifications as soon as they come in.

– Information Overload in Chats: While each Slack or Teams message may be brief, the number of messages can be very high, contributing to notification overload. Group channels, @mentions, and rapid-fire discussions can produce a constant stream of updates. A workplace survey by RescueTime noted that this era of hyper-collaboration leaves most workers feeling perpetually behind – in fact, only 10% of people felt “in control” of their day amid the barrage of pings and meetings (blog.rescuetime.com). The majority reported that frequent interruptions and the sheer volume of communication make it difficult to keep up. This indicates that though instant messaging reduces per-message response time, it can increase context-switching and cognitive load as employees attempt to continuously monitor and clear new messages.

In summary, tools like Slack and Teams enable much faster response times than email. Employees can resolve questions in real-time and spend fewer minutes composing formal replies. However, the expectation of immediacy means workers are almost continuously tending to messages. The data underscores a trade-off: faster communication cycles versus a greater frequency of interruptions.

Implications for Productivity and Decision-Making  

Analyzing these findings on response times and communication habits provides actionable insights for managers and teams aiming to improve efficiency:  

– Productivity Trade-offs: Faster response channels (chat) can speed up problem resolution, but too many interruptions can hurt overall productivity. Studies have shown that after a notification disrupts focused work, it can take over 20 minutes to refocus (a figure often cited in productivity research). Thus, while an employee might answer a Slack message in 2 minutes, the unseen cost in lost concentration could be much higher. The prevalence of multi-channel communication today – with workers toggling between email, chat, and other apps – can lead to continual context switching. When 90% of workers feel they lack control of their day (blog.rescuetime.com), it signals that the benefits of instant communication might be undermined by attention fragmentation. Decision-makers should weigh these productivity costs when encouraging “always-available” communication. Setting guidelines (like intended response windows or “quiet hours”) can help balance responsiveness with focus time.

– Message Overload and Employee Well-being: The data on communication overload (hundreds of emails weekly, dozens of chat notifications daily) correlates with stress and burnout. Employees spending 11 hours a week just writing emails (slack.com) or feeling the need to check messages at night are at risk of exhaustion. Missed emails causing important information to slip through the cracks (affecting ~1 in 3 workers (www.salesforce.com)) show that simply increasing message volume doesn’t guarantee effective communication. Organizations may consider investing in better email management training, intelligent filtering tools, or integrating platforms (e.g., funneling important messages into a single dashboard) to help employees more efficiently clear their inboxes and queues. The fact that less than half of email content gets fully digested by recipients (slack.com) is a red flag – improving message clarity or choosing the right channel for the message (email vs. chat vs. a call) could improve uptake and reduce back-and-forth. 

– Choosing the Right Channel: Data-driven insights can guide teams on when to use email versus instant messaging. Email’s slower pace might be suitable for lengthy, complex discussions or when recipients might not be immediately available. However, if the average reply takes 3+ hours (www.prnewswire.com), urgent issues should be moved to a faster channel. Conversely, if chat interruptions are hindering deep work, non-urgent communications could be funneled back to email or a dedicated time slot. For example, a policy might be that emails can expect same-day response, whereas Slack messages imply a need for quicker acknowledgment (within minutes to an hour). By aligning expectations with the response-time data (e.g. knowing that most emails won’t get an instant reply, but Slack might, albeit at a cognitive cost), teams can set more reasonable service-level agreements for internal communication. This prevents frustration on both sides – senders know what to expect, and responders can organize their work without feeling incessantly on-call.

– Monitoring and Adjustment: Finally, organizations should continuously monitor communication load metrics – such as average email backlog, response times, or time spent in messaging apps – as key performance indicators for operational efficiency. An upward trend in time-to-respond or a growing portion of the day spent on messaging might indicate the need for intervention (hiring support staff, instituting “no chat” focus periods, adopting smarter collaboration tools, etc.). The fact that communication time has risen 50% in two decades (blog.rescuetime.com) suggests that old work processes need updating. Leveraging productivity reports from tools (for instance, Microsoft’s MyAnalytics or Teams analytics, which track response habits) could provide concrete data to inform decisions. The goal would be to reduce unnecessary messaging and expedite necessary messaging. Some companies have turned to features like priority markers, “Do Not Disturb” modes, or AI email triage in Outlook/Gmail to help employees manage the deluge more effectively. Indeed, Slack’s own study hints at AI assistance as a future remedy, given employees’ struggles with current volumes (www.salesforce.com).

Decision-Making Takeaway: The empirical evidence underscores that both extremes – slow email and hyper-reactive chat – have downsides. Effective inter-team communication is about finding the right balance. By examining the specific metrics (hours spent, average response times, unread rates, etc.), leaders can craft policies that improve information flow while guarding employees’ time. For instance, if employees are spending 11 hours a week on email that few people read, shifting some discussions to a more transparent, real-time medium (like Teams channels or Slack) could reclaim lost time (slack.com). Conversely, if instantaneous messaging is overwhelming staff, instituting norms around expected reply times (perhaps Slack messages can wait an hour unless truly urgent) might relieve pressure. Data-driven decisions – such as setting an “email response SLA” based on the 90-minute average (zipdo.co) or scheduling no-meeting blocks to allow catching up on messages – can lead to more efficient and healthier communication practices.

Inter-team communication dynamics are quantitatively shifting: employees juggle high volumes of email with multi-hour response lags, and high-frequency chat with minute-level response expectations. Surveys and studies provide concrete figures – from the 3+ hour average email turnaround (www.prnewswire.com), to the dozens of daily messages across platforms, to the 9–11 hours per week spent just handling written communications (slack.com) (www.salesforce.com). These numbers highlight pain points and opportunities. By understanding the current state (backed by data), organizations can make informed choices about which tools to use, how to train employees in communication skills, and how to set boundaries that maximize productivity. The key is to leverage the strengths of each medium (thoroughness of email, speed of Slack/Teams) while mitigating their weaknesses (email overload, notification fatigue). Ultimately, the goal is to reduce the time it takes to clear, resolve, or respond to messages so that teams can focus on deeper work – without sacrificing clarity or work-life balance in the process. The evidence gathered here serves as a benchmark for those decisions, ensuring they are rooted in how employees actually experience communication day-to-day.

Re-Calculating Communication Lag by including Non Business Hours

To calculate a reasonable average email response time including non-business hour delays and weekend delays, let’s consider some assumptions:

1. Average response time during work hours: 3 hours 38 minutes (or 3.63 hours)
2. Non-business hours: Assuming the average employee works an 8-hour day (e.g., 9 AM – 5 PM), non-business hours would be the remaining 16 hours of the day.
3. Weekends: Typically, there are 48 non-work-hours during weekends.

Calculation Steps:

• Daily Non-Business Hour Impact:
• Let’s assume that emails received during non-business hours on a weekday are responded to on the next business day.
• If an email arrives after work hours, the delay would average to roughly halfway through non-business hours: 16 hours/2 = 8 hours
• Weekend Impact:
• For emails received over the weekend, the delay at the start of the next workweek would average about halfway through the weekend: 48 hours/2 = 24 hours

Calculating Average Total Delays:

1. Emails received during work hours: 3.63 hours
2. Emails received during non-business hours: (3.63 hours + 8 hours) = 11.63 hours
3. Emails received during weekends: (3.63 hours + 24 hours) = 27.63 hours

Assuming emails are received uniformly over time with each category having equal likelihood:

[ \text{Average response time} = \frac{3.63 + 11.63 + 27.63}{3} = 14.30 \text{ hours} ]

The final tally

Including non-business and weekend delays, a reasonable average email response time could be approximately 14.30 hours.

The Influence of Communication Lag on Task Completion

1. Task Complexity:
• Simple tasks requiring one or two clarifications may have a linear relationship.
• Complex tasks needing multiple back-and-forth exchanges can have an exponential impact due to compounded delays.
2. Dependency:
• Tasks that are serially dependent on responses can see increased times if each sequential step faces communication lag.
• In parallel processes, some parts may progress while others wait, leading to a more variable influence.
3. Number of Communications:
• More communications could mean compounded delays, potentially making the effect non-linear.
4. Communication Modes:
• Different modes like email, chats, or meetings can have varying average lags associated. A mix of these can change the overall impact.

General Observations:

• Linear Impact: If each task step involves a standard, single communication, and tasks are independent, the additional time due to communication lag might average out to a linear addition correlated with response times.
• Non-linear Impact: In fields where:
• Tasks are interdependent
• Multiple iterations of communication are needed
• Delays are compounded due to bottlenecks
• The additional completion time could grow exponentially with more communications.

We conclude this analysis to generally observe that communication lag adds non-linearly to the time completion of complex tasks but may approximate linearity in simpler or independent task contexts.

Reducing Lag Time when Starting Tasks

In collaborative projects, the time from assignment to actual work (“task start lag”) can be significant. This lag arises whenever a task sits idle before anyone begins it. Contributing factors include assignment acceptance delay (waiting for the assignee to acknowledge or pick up the task), busy schedules (queuing behind higher-priority work), and non-working hours (nights or weekends where no work happens).  Although direct studies on “task start lag” in teams are rare, analogous data show that even short delays can have outsized effects. For example, Zendesk’s 2023 customer-experience report – cited via an industry blog – found that 64% of U.S. customers will defect after just two bad experiences (intl.delight.fit). Crucially, it notes that “weekend wait times of several hours—or even a few minutes—can be enough to trigger churn” (intl.delight.fit). In other words, even minute-level idle periods (like those caused by tasks waiting over a weekend) severely degrade outcomes. By analogy, team tasks suffer similar pain: each extra hour or day of waiting can dramatically stretch the project timeline. 

Major sources of task-start lag include:  

– Assignment Acknowledgment Delay:  A task often isn’t started until the assignee has seen and accepted it. If a task is assigned late in the day, it typically sits overnight.  For instance, a ticket created at 5:00 PM is unlikely to be addressed until the next morning. Empirical traces of Kanban or issue-tracking boards commonly show tasks staying in a “Ready” or “Assigned” column for many hours – often a half day to a full business day – before anyone begins work.

– Competing Workload Queues:  Team members usually juggle multiple tasks. Studies (e.g. Asana’s Anatomy of Work reports) indicate that 80–90% of knowledge workers feel they have more to do than time allows.  In practice, this means a newly assigned task often queues behind existing tasks. For example, if an engineer has 4 active tasks and one new task arrives, that new task might not start until one of the first 4 is done. In high-load environments this can add a full day or more of delay per task. (Some industry surveys show that employees spend only ~2–3 hours per day on any given task due to context-switching, implying substantial waiting times between task starts.)

– Non-Working Hours (Daily Off-Time):  Standard work schedules (e.g. 8:00–17:00 Monday–Friday) create built-in dead time. Any task assigned outside that window automatically waits until the next available work slot. For example, a task given at 10:00 PM cannot practically be addressed until 8:00 AM the next day – an immediate ~10-hour lag. Over a week, nightly off-hours accumulate (roughly 40 hours of idle time). Even tasks assigned at 4:00 PM often are not started until the following morning (~12–16 hours of delay).  In project scheduling terms, most software tools automatically shift such tasks forward; this “meeting calendar” effect alone typically adds 0.5–1 full day of lag per task when averaged over a team.

– Weekend Gaps:  The largest single jump occurs when tasks cross a weekend. A task assigned on Friday afternoon often sits untouched until Monday morning – roughly 48–60 hours of idle time.  In other words, a 5-day task can effectively become a 7-day span with weekends.  The sensitivity of outcomes to weekend delays is stark: as cited above, even minutes of extra wait on a Saturday or Sunday “can be enough to trigger churn” (intl.delight.fit). Translating this to project work, a Friday-evening assignment is roughly equivalent to adding 2 workdays of lead time.  Thus, any tasks scheduled around weekends routinely see their start dates slip by several tenths of their nominal duration.

These factors compound multiplicatively.  For example, consider a task assigned Thursday at 5 PM. It sits overnight (~12h), across Friday (assuming busy schedule adds another day of waiting), then sits all weekend (~48h), and is finally picked up Monday (plus possibly waiting for resources). What might have been a 24-hour task can easily stretch into a week. In practice, product development teams often observe that project timelines expand by 20–50% (or more) once these real-world lags are accounted for.  One way to see the impact is via an analogy: Zentdesk’s finding that 64% of customers churn after two bad experiences (intl.delight.fit) suggests that just two significant delays (e.g. assignment lag + weekend lag) can “lose” the project schedule just as decisively as a bad customer interaction. 

Key outcomes:  Quantitatively, if you bake in start lags, a project’s lead time balloons. For example, a linear chain of 10 tasks each estimated 1 day can swell to 15–20 days total once you add ~0.5–1 day lag per task (common rule-of-thumb).  Critical tasks slipping over a weekend effectively add 2 days each. These delays show up in measurable metrics: in kanban/CFD charts, the waiting time often dwarfs active time; in project tracking, completion dates consistently fall behind original plans unless buffers are added.  In turn, this affects deadlines, quality (more rushed execution), and even team morale.

To support decision-making, teams can quantify these effects. For instance, if the median assignment delay is 8 hours and nightly calendar cutoffs add 12 hours, that’s 20 hours idle per task on average (about 2.5 workdays per week). If two such delays occur, it’s 4+ days.  Software tools (like MS Project) formalize this: tasks crossing non-working windows are automatically deferred to the next slot.  The cited industry data reinforce the point: even “small” waiting times drastically change outcomes (intl.delight.fit). In practical terms, planners should factor in “lag buffers”: e.g. treat a 5-day task as 7 days if crossing a week boundary, or ensure Monday–Friday scheduling so minimal work spills into weekends. Techniques like rotating on-call duty or asynchronous handoffs can mitigate the weekend lag.  Overall, the analysis shows that start lags are non-negligible and should be quantified.  

Data Sources: Wherever possible, we rely on published figures and reports. In particular, the Zendesk Customer Experience Trends report (2023) is cited by an industry blog, noting “64% of U.S. customers are likely to defect after just two bad experiences,” and specifically that “weekend wait times of several hours— or even a few minutes—can be enough to trigger churn” (intl.delight.fit). While from a customer service context, this underscores how even minute-level delays have serious consequences.  Project-scheduling documentation (e.g. Microsoft’s Project guides) similarly confirms that tasks cannot occupy non-working periods. These insights provide the numeric grounding: short delays (hours) and typically-expected weekend gaps have been empirically linked to large impacts. The patterns above are consistent with both these findings and with common industry experience in Agile and waterfall project data (where delay factors of 1.2–1.5× or more are routinely observed when accounting for real-world interruptions). 

Statistical findings were drawn from industry reports. In particular, Zendesk’s 2023 “Customer Experience Trends” (as summarized by International Delight’s blog article) provides the key delay metrics (intl.delight.fit). Project management best practices (e.g. Microsoft Project official docs on calendars) are also consistent with the documented delays. Further data on knowledge-worker multitasking (e.g. Asana’s Anatomy of Work reports) reinforce the prevalence of queued tasks and uncompleted workloads in modern teams. These sources collectively show that task-start lags are real, measurable phenomena with clear impacts on completion times. 

The article emphasizes the importance of reducing communication and production cycle times to enhance customer satisfaction. It discusses how AI can expedite processes, and how Inspira’s Water platform quantifies saved delivery time. The document highlights the impacts of communication latency, especially through email and instant messaging, on productivity and stresses the need for a balance between communication modes to optimize efficiency and minimize project delays.

Summary

In conclusion, delayed work processes lead to customer dissatisfaction and hinder cashflow.

Utilizing AI can accelerate task completion by addressing key areas of friction:

1. Enhancing the speed of communication within teams and with stakeholders
2. Minimizing delays in initiating tasks
3. Reducing the time required to complete tasks

AI is significantly improving these areas, thereby elevating customer and stakeholder satisfaction. Water’s conservative estimates of ‘delivery time’ savings offer near real-time insight into proof of value… mere moments after tasks have been completed by Sidekicks.
