### FAQ

#### Is a PMP certification worth it?

A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations.

#### What are the best certifications for project managers?

The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation.

#### How does PMI support career growth for professionals?

PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers.

#### What is the PMBOK® Guide?

The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery.

#### How is AI changing project management?

AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment.  PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes.

#### What are the most important skills for a project manager?

Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates.


#### How can I get involved with the PMI community?

Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections.

#### What is the difference between PMP and CAPM?

The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification.

#### How does PMI support social impact?
PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world.

![Inc. logo](https://static.time.com/v3/assets/bltea6093859af6183b/blt8f6bd3ad283e7bb9/69875fd2a988ca9fc66a9b4e/inc-logo.png?branch=production&width=256&quality=75&auto=webp)

Where the mechanics of writing are concerned, I’m far from perfect. One example: I always struggle with _who_ and _whom._ (Sometimes I’ll even rewrite a sentence just so I won’t have to worry about which is correct.)

And that’s a real problem. The same way one misspelled word can get your résumé tossed onto the reject pile, one misused word can negatively impact your entire message.

Fair or unfair, it happens all the time–so let’s make sure it doesn’t happen to you.

My post [30 Incorrectly Used Words That Can Make You Look Bad](http://www.inc.com/jeff-haden/32-incorrectly-used-words-that-can-make-us-look-stupid.html) resulted in readers providing a number of other examples of misused words, and here are some of them. Once again I’ve picked words that are typically used in business settings, with special emphasis on words that spell checker won’t correct.

Here we go:

**_Advise_** **and** **_advice_**

Aside from the two words being pronounced differently (the _s_ in _advise_ sounds like a_z_), _advise_ is a verb while _advice_ is a noun. Advice is what you give (whether or not the recipient is interested in that gift is a different issue altogether) when you advise someone.

So, “Thank you for the advise” is incorrect, while “I advise you not to bore me with your advice in the future” is correct if pretentious.

If you run into trouble, just say each word out loud and you’ll instantly know which makes sense; there’s no way you’d ever say, “I advice you to…”

**_Ultimate_** **and** **_penultimate_**

Recently I received a pitch from a PR professional that read, “(Acme Industries) provides the penultimate value-added services for discerning professionals.”

As [Inigo would say](https://www.youtube.com/watch?v=YIP6EwqMEoE), “I do not think it means what you think it means.”

_Ultimate_ means the best, or final, or last. _Penultimate_ means the last but one, or second to last. (Or, as a Monty Python-inspired Michelangelo would say, [“the Penultimate Supper!”](https://www.youtube.com/watch?v=l9Aj7W3g1qo))

But _penultimate_ doesn’t mean second-best. Plus, I don’t think my PR friend meant to say her client offered second-class services. (I think she just thought the word sounded cool.)

Also, keep in mind that using _ultimate_ is fraught with hyperbolic peril. Are you–or is what you provide–really the absolute best imaginable? That’s a tough standard to meet.


**_Well_** **and** **_good_**

Anyone who has children uses _good_ more often than he or she should. Since kids pretty quickly learn what _good_ means, “You did good, honey” is much more convenient and meaningful than “You did well, honey.”

But that doesn’t mean _good_ is the correct word choice.

_Good_ is an adjective that describes something; if you did a good job, then you do good work. _Well_ is an adverb that describes how something was done; you can do your job well.

Where it gets tricky is when you describe, say, your health or emotional state. “I don’t feel well” is grammatically correct, even though many people (including me) often say, “I don’t feel too good.” On the other hand, “I don’t feel good about how he treated me” is correct; no one says, “I don’t feel well about how I’m treated.”

Confused? If you’re praising an employee and referring to the outcome say, “You did a good job.” If you’re referring to how the employee performed say, “You did incredibly well.”


And while you’re at it, stop saying _good_ to your kids and use _great_ instead, because no one–especially a kid–ever receives too much praise.

**_If_** **and** **_whether_**

_If_ and _whether_ are often interchangeable. If a yes/no condition is involved, then feel free to use either: “I wonder whether Jim will finish the project on time” or “I wonder if Jim will finish the project on time.” (_Whether_ sounds a little more formal in this case, so consider your audience and how you wish to be perceived.)

What’s trickier is when a condition is not involved. “Let me know whether Marcia needs a projector for the meeting” isn’t conditional, because you want to be informed either way. “Let me know if Marcia needs a projector for the meeting” is conditional, because you only want to be told if she needs one.

And always use _if_ when you introduce a condition. “If you hit your monthly target, I’ll increase your bonus” is correct; the condition is hitting the target and the bonus is the result. “Whether you are able to hit your monthly target is totally up to you” does not introduce a condition (unless you want the employee to infer that your thinly veiled threat is a condition of ongoing employment).


**_Stationary_** **and s** **_tationery_**

You write on stationery. You get business stationery, such as letterhead and envelopes, printed.

But that box of envelopes is not stationary unless it’s not moving–and even then it’s still stationery.

**_Award_** **and** **_reward_**

An award is a prize. Musicians win Grammy Awards. Car companies win J.D. Power awards. Employees win Employee of the Month awards. Think of an award as the result of a contest or competition.

A reward is something given in return for effort, achievement, hard work, merit, etc. A sales commission is a reward. A bonus is a reward. A free trip for landing the most new customers is a reward.

Be happy when your employees win industry or civic awards, and reward them for the hard work and sacrifices they make to help your business grow.

**_Sympathy_** **and** **_empathy_**

Sympathy is acknowledging another person’s feelings. “I am sorry for your loss” means you understand the other person is grieving and want to recognize that fact.


Empathy is having the ability to put yourself in the other person’s shoes and relate to how the person feels, at least in part because you’ve experienced those feelings yourself.

The difference is huge. Sympathy is passive; empathy is active. (Here’s a [short video by Brené Brown](https://www.youtube.com/watch?v=1Evwgu369Jw) that does a great job of describing the difference–and how empathy fuels connection while sympathy drives disconnection.)

Know the difference between sympathy and empathy, live the difference, and you’ll make a bigger difference in other people’s lives.

**_Criterion_** **and** **_criteria_**

A criterion is a principle or standard. If you have more than one criterion, those are referred to as criteria.

But if you want to be safe and you only have one issue to consider, just say _standard_or _rule_ or _benchmark._ Then use _criteria_ for all the times there are multiple specifications or multiple criterion (OK, standards) involved.

**_Mute_** **and** **_moot_**

Think of _mute_ like the button on your remote; it means unspoken or unable to speak. In the U.S., _moot_ refers to something that is of no practical importance; a moot point is one that could be hypothetical or even (gasp!) academic. In British English, _moot_can also mean debatable or open to debate.


So if you were planning an IPO, but your sales have plummeted, the idea of going public could be moot. And if you decide not to talk about it anymore, you will have gone mute on the subject.

**_Peak_** **and** **_peek_**

A peak is the highest point; climbers try to reach the peak of Mount Everest. _Peek_means quick glance, as in giving major customers a sneak peek at a new product before it’s officially unveiled, which hopefully helps sales peak at an unimaginable height.

Occasionally a marketer will try to “peak your interest” or “peek your interest,” but in that case the right word is _pique,_ which means “to excite.” (_Pique_ can also mean “to upset,” but hopefully that’s not what marketers intend.)

**_Aggressive_** **and** **_enthusiastic_**

_Aggressive_ is a very popular business adjective: aggressive sales force, aggressive revenue projections, aggressive product rollout. But unfortunately, _aggressive_ means ready to attack, or pursuing aims forcefully, possibly unduly so.


So do you really want an “aggressive” sales force?

Of course, most people have seen _aggressive_ used that way for so long they don’t think of it negatively; to them it just means hard-charging, results-oriented, driven, etc., none of which are bad things.

But some people may not see it that way. So consider using words like _enthusiastic_,_eager, committed, dedicated,_ or even (although it pains me to say it) _passionate._

**_Then_** **and** **_than_**

_Then_ refers in some way to time. “Let’s close this deal, and then we’ll celebrate!” Since the celebration comes after the sale, _then_ is correct.

_Then_ is also often used with _if._ Think in terms of if-then statements: “If we don’t get to the office on time, then we won’t be able to close the deal today.”

_Than_ involves a comparison. “Landing Customer A will result in higher revenue than landing Customer B,” or “Our sales team is more committed to building customer relationships than the competition is.”


**_Evoke_** **and** **_invoke_**

To evoke is to call to mind; an unusual smell might evoke a long-lost memory. To invoke is to call upon some thing: help, aid, or maybe a higher power.

So hopefully all your branding and messaging efforts evoke specific emotions in potential customers. But if they don’t, you might consider invoking the gods of commerce to aid you in your quest for profitability.

Or something like that.

**_Continuously_** **and** **_continually_**

Both words come from the root _continue,_ but they mean very different things._Continuously_ means never ending. Hopefully your efforts to develop your employees are continuous, because you never want to stop improving their skills and their future.

_Continual_ means whatever you’re referring to stops and starts. You might have frequent disagreements with your co-founder, but unless those discussions never end (which is unlikely, even though it might feel otherwise), then those disagreements are continual.


That’s why you should focus on continuous improvement but only plan to have continual meetings with your accountant: The former should never, ever stop, and the other (mercifully) should.

**_Systemic_** **and** **_systematic_**

If you’re in doubt, _systematic_ is almost always the right word to use. _Systematic_ means arranged or carried out according to a plan, method, or system. That’s why you can take a systematic approach to continuous improvement, or do a systematic evaluation of customer revenue or a systematic assessment of market conditions.

_Systemic_ means belonging to or affecting the system as a whole. Poor morale could be systemic to your organization. Or bias against employee diversity could be systemic.

So if your organization is facing a pervasive problem, take a systematic approach to dealing with it—that’s probably the only way you’ll overcome it.

**_Impact_** **and** **_affect_** **(and** **_effect_** **)**

Many people (including until recently me) use _impact_ when they should use _affect_. _Impact_ doesn’t mean to influence; _impact_ means to strike, collide, or pack firmly.


_Affect_ means to influence: “Impatient investors affected our rollout date.”

And to make it more confusing, _effect_ means to accomplish something: “The board effected a sweeping policy change.”

How you correctly use _effect_ or _affect_ can be tricky. For example, a board can affect changes by influencing them and can effect changes by directly implementing them. Bottom line, use _effect_ if you’re making it happen, and _affect_ if you’re having an impact on something that someone else is trying to make happen.

As for nouns, _effect_ is almost always correct: “Employee morale has had a negative effect on productivity.” _Affect_ refers to an emotional state, so unless you’re a psychologist, you probably have little reason to use it.

So stop saying you’ll “impact sales” or “impact the bottom line.” Use _affect._

(And feel free to remind me when I screw that up, because I feel sure I’ll backslide.)

**_Between_** **and** **_among_**

Use _between_ when you name separate and individual items. “The team will decide between Mary, Marcia, and Steve when we fill the open customer service position.” Mary, Marcia, and Steve are separate and distinct, so _between_ is correct.


Use _among_ when there are three or more items but they are not named separately. “The team will decide among a number of candidates when we fill the open customer service position.” Who are the candidates? You haven’t named them separately, s o_among_ is correct.

And we’re assuming there are more than two candidates; otherwise you’d say _between._ If there are two candidates you could say, “I just can’t decide between them.”

**_Everyday_** **and** **_every day_**

_Every day_ means, yep, every day—each and every day. If you ate a bagel for breakfast each day this week, you had a bagel every day.

_Everyday_ means commonplace or normal. Decide to wear your “everyday shoes” and that means you’ve chosen to wear the shoes you normally wear. That doesn’t mean you have to wear them every single day; it just means wearing them is a usual occurrence.

Another example is _along_ and _a long:_ _Along_ means moving in a constant direction or a line, or in the company of others, while _a long_ means of great distance or duration. You wouldn’t stand in “along line,” but you might stand in a long line for a long time, along with a number of other people.


A couple more examples: _a while_ and _awhile_, and _any way_ and _anyway_.

If you’re in doubt, read what you write out loud. It’s unlikely you’ll think “Is there anyway you can help me?” sounds right.
